	Note 2 — Stock-Based Compensation
	Cynosure recorded stock-based compensation expense of $0.9 million and $0.7 million for the three months ended September 30, 2013 and 2012, respectively. Cynosure recorded stock-based compensation expense of $2.6 million and $2.1 million for the nine months ended September 30, 2013 and 2012, respectively. Cynosure capitalized $20,000 and $17,000 of stock-based compensation expense as part of inventory during the nine months ended September 30, 2013 and 2012, respectively.
	Total stock-based compensation expense was recorded to cost of revenues and operating expenses based upon the functional responsibilities of the individual holding the respective options, as follows:

	Cash received from option exercises was $2.6 million and $6.8 million during the nine months ended September 30, 2013 and 2012, respectively.
	Cynosure granted 386,010 and 374,290 stock options during the nine months ended September 30, 2013 and 2012, respectively. Cynosure has elected to use the Black-Scholes model to determine the weighted average fair value of options. The weighted average fair value of the options granted during the nine months ended September 30, 2013 and 2012 was $13.10 and $8.94, respectively, using the following assumptions:
		Nine Months Ended
		September 30,
		2013		2012
	Risk-free interest rate	0.79% - 1.49%		0.63% - 0.86%
	Expected dividend yield	—		—
	Expected term	4.8 years		5.8 years
	Expected volatility	54% - 56%		56% - 57%
	Estimated forfeiture rate	5%		5%
	Option-pricing models require the input of various subjective assumptions, including the option’s expected life and the price volatility of the underlying stock. Cynosure’s estimated expected stock price volatility is based on its own historical volatility. Cynosure’s expected term of options granted during the nine months ended September 30, 2013 represents the weighted average period of time that options granted are expected to be outstanding giving consideration to vesting schedules and Cynosure’s historical exercise patterns. Cynosure’s expected term of options granted in the nine months ended September 30, 2012 was derived from the short-cut method. The risk-free rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The dividend yield of zero is based on the fact that Cynosure has never paid cash dividends and has no present intention to pay cash dividends.

Fair Value Disclosures [Abstract]	'
Fair Value	'
	Note 4 — Fair Value
	U.S. GAAP establishes a framework for measuring fair value under generally accepted accounting principles and enhances disclosures about fair value measurements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes the following fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:
		•		Level 1 — Quoted prices in active markets for identical assets or liabilities.
		•		Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable markets data for substantially the full term of the assets or liabilities.
		•		Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The following table represents Cynosure’s fair value hierarchy for its financial assets (cash equivalents and marketable securities) measured at fair value as of September 30, 2013 (in thousands):
			Level 1		Level 2		Level 3		Total

	During the nine months ended September 30, 2013, there were no significant transfers in and out of Level 1 and Level 2. Cynosure did not have any Level 3 financial assets at September 30, 2013 or December 31, 2012.

Business Combinations [Abstract]	'
Acquisition	'
	Note 6 — Acquisition
	Palomar Medical Technologies, Inc.
	On June 24, 2013, Cynosure acquired Palomar Medical Technologies, Inc. (Palomar). The acquisition has complemented and broadened Cynosure’s product lineup with the addition of Palomar’s intense pulsed light, fractional laser and diode aesthetic systems, doubled the number of patents in Cynosure’s portfolio and enhanced Cynosure’s global distribution network. As a result of the transaction, former Palomar stockholders, in the aggregate, received for their shares of Palomar common stock $145.8 million in cash and 6.0 million shares of Cynosure Class A common stock. The total consideration was valued at $287.2 million, based upon the closing price of Cynosure Class A common stock on June 24, 2013. This acquisition was considered a business acquisition for accounting purposes. The goodwill recognized is attributable to synergies associated with the Palomar technology which has been integrated with Cynosure’s product portfolio and distributed throughout the U.S. and international distribution channels.
	Cynosure has retained an independent valuation firm to assess the fair value of the identifiable intangible assets and certain tangible assets acquired, and is also currently assessing the fair value of other assets acquired and liabilities assumed. Pro forma financial information was filed with the SEC within the applicable time period. Cynosure has preliminarily allocated the purchase price to the net tangible and intangible assets based on their estimated fair values as of June 24, 2013. As such, the fair value of the assets acquired and liabilities assumed presented in the table below are provisional and will be finalized in a later period once the fair value procedures are completed. During the third quarter of 2013, Cynosure revised its estimates (in thousands) of the assets acquired and liabilities assumed in regards to the acquisition of Palomar, and as a result, reduced goodwill from $91,037 at June 30, 2013 to $90,856 at September 30, 2013. Accounts receivable increased by $341, due primarily to a reduction in bad debt reserves. Inventory decreased by $4,218, due to a revised calculation of fair value, as well as transferring demo equipment to fixed assets, per Cynosure policy. Fixed assets increased by $2,724 due to the transfer of demo equipment from inventory, as well as an increase in estimated value of the building acquired. Accrued expenses increased by $179 due to additional miscellaneous expenses. Other long-term liabilities decreased by $1,513 due to changes in certain tax reserves.
	The allocation of the acquisition purchase price is subject to adjustment upon finalization of the fair value procedures, and therefore the current measurements of accounts receivable, inventory, property and equipment, intangible assets acquired, goodwill and assumed liabilities are subject to change.
	The following table summarizes the preliminary purchase price allocation, net of $117.9 million in cash, cash equivalents and marketable securities acquired (in thousands):
	Purchase price:
	Cash and stock paid	$	287,204
	Cash, cash equivalents and marketable securities acquired		(117,929	)
	Purchase price, net	$	169,275
	Assets (liabilities) acquired:
	Accounts receivable		9,948

	Deferred revenue		(3,010	)
	Deferred tax liability		(5,451	)
	Other long-term liabilities		(1,593	)
	Total	$	169,275
	The amounts included in revenue within the consolidated statement of operations, relating to the acquisition of Palomar, for the three and nine months ended September 30, 2013 were $21.1 million and $26.2 million, respectively.
	As a result of the integration of the operations of Palomar into Cynosure’s operations, disclosures of earnings included in the accompanying consolidated statement of operations since the acquisition date is not practicable.
	The following unaudited pro forma condensed consolidated operating results for the three and nine months ended September 30, 2013 and 2012 summarize the combined results of operations for Cynosure and Palomar. The unaudited pro forma condensed consolidated operating results includes the business combination accounting effects as if the acquisition had been completed as of January 1, 2012 (for both the 2013 and 2012 period results) after giving effect to certain adjustments. These pro forma financial statements are for informational purposes only and are not necessarily indicative of the operating results that would have occurred if the transaction had occurred on such date. No effect has been given for synergies, if any, that may be realized through the acquisition.

	The unaudited consolidated pro forma financial information above includes significant, non-recurring adjustments made to account for certain costs which would have been incurred if the acquisition had been completed on January 1, 2012, including $21.7 million in change of control severance payments and $2.4 million associated with the step up in fair value of finished goods inventory acquired through the acquisition.
	During the three and nine months ended September 30, 2013, Cynosure incurred $7.1 million and $28.7 million, respectively, in selling, general and administrative costs associated with the acquisition of Palomar. In connection with the acquisition of Palomar, certain terminated Palomar employees were, and certain continuing Palomar employees are, entitled to severance benefits in specified circumstances associated with the change of control of Palomar. In connection with the acquisition and these change of control severance arrangements, Cynosure incurred $3.1 million and $21.7 million, respectively, of compensation expense during the three and nine months ended September 30, 2013. Cynosure expects to incur an additional $1.6 million of compensation expense in the fourth quarter and approximately $0.7 million during each of the first two quarters of 2014 in connection with these change in control severance payments. Costs associated with the acquisition of Palomar are primarily recorded in the general and administrative expenses within the consolidated statement of operations.
	During the three and nine months ended September 30, 2013, respectively, Cynosure incurred $0.1 million and $0.6 million in equity issuance costs associated with the acquisition of Palomar. These amounts were recorded to additional paid-in capital.

	Cynosure acquired $40.3 million of identifiable intangible assets in the Palomar acquisition, of which $18.4 million was assigned to technology patents, $11.6 million was assigned to customer relationships and $10.3 million was assigned to trademarks. These identifiable intangible assets are being amortized on an accelerated basis up to a 20-year period and are included in the table above.
	Cynosure is currently evaluating the fair value of assets acquired and liabilities assumed from the Palomar acquisition, including identifiable intangible assets and their related amortization periods. As such, the $40.3 million in intangible assets presented in the table above are provisional and will be finalized in a later period once the fair value procedures are completed.

Long-Lived Assets Held for Sale	'
	Note 9 — Long-Lived Assets Held for Sale
	In accordance with ASC 360, Cynosure considers properties to be assets held for sale when all of the following criteria are met:
		•	management commits to a plan to sell a property;
		•	the property is available for immediate sale in its present condition;
		•	an active program to locate a buyer and other actions required to complete the plan to sell the asset have been initiated;
		•	sale of the property is probable and Cynosure expects the completed sale will occur within one year;
		•	the property is actively being marketed for sale at a price that is reasonable given its current market value; and
		•	it is unlikely that the disposal plan will be significantly modified or discontinued.
	Upon designation as an asset held for sale, Cynosure records the carrying value of each property at the lower of its carrying value or its estimated fair value, less estimated costs to sell, and Cynosure ceases depreciation as of the date the asset is classified as held for sale.
	Effective June 24, 2013, as part of the acquisition of Palomar, Cynosure acquired the land and building at 15 Network Drive in Burlington, MA. In early September 2013, Cynosure began to market the land and building. Cynosure received a letter of intent from a potential buyer dated October 7, 2013. Given these facts and circumstances, Cynosure has concluded that it had met the requirements to classify the land and building in Burlington, MA as held for sale as of September 1, 2013.
	As of September 30, 2013, Cynosure has classified $26.4 million in long-lived assets held for sale, exclusively related to the land and building in Burlington, MA. During the three months ended September, 30, 2013, Cynosure incurred an impairment loss of $0.5 million resulting from the subsequent measurement of the assets held for sale at fair value less costs to sell. This loss is recorded in the general and administrative expenses within the consolidated statement of operations.

Earnings Per Share [Abstract]	'
Net (Loss) Income Per Common Share	'
	Note 12 — Net (Loss) Income Per Common Share
	Basic net (loss) income per share is determined by dividing net (loss) income by the weighted average common shares outstanding during the period. Diluted net (loss) income per share is determined by dividing net (loss) income by the diluted weighted average shares outstanding during the period. Diluted weighted average shares reflect the dilutive effect, if any, of common stock options based on the treasury stock method. For the three and nine months ended September 30, 2013, there are no outstanding Class B shares, and Cynosure may not issue Class B shares in the future. For the three and nine months ended September 30, 2012, common shares outstanding include both Class A and Class B as each share participated equally in earnings. Class B shares were convertible at any time into shares of Class A on a one-for-one basis at the option of the holder.
	A reconciliation of basic and diluted shares is as follows:
		Three Months Ended					Nine Months Ended
		September 30,					September 30,
		2013			2012		2013			2012
	Net (loss) income	$	(1,281	)	$	3,423	$	(8,996	)	$	6,922

	Diluted net (loss) income per share	$	(0.06	)	$	0.25	$	(0.49	)	$	0.52
	For the three and nine months ended September 30, 2013, the number of basic and diluted weighted average shares outstanding was the same, as any increase in the number of shares of common stock equivalents for the three and nine months ended September 30, 2013 would be antidilutive based on the net loss for the period. For the three and nine months ended September 30, 2013, respectively, outstanding options to purchase 1.0 million and 1.1 million shares were excluded from the computation of diluted earnings per share because their inclusion would have been antidilutive.
	For the three and nine months ended September 30, 2012, respectively, options to purchase 0.2 million and 0.7 million shares of Cynosure’s Class A common stock were excluded from the calculation of diluted weighted average common shares outstanding as their effect was antidilutive.

	Note 15 — Income Taxes
	During the three months ended September 30, 2013 and 2012, Cynosure recorded an income tax expense of $0.6 million and $0.3 million, respectively, representing an effective tax rate of (88%) and 9%, respectively. The income tax provision for the three months ended September 30, 2013 is primarily attributable to the tax provision on the earnings of our foreign and domestic operations.
	At September 30, 2013, Cynosure had unrecognized tax benefits, inclusive of accrued interest, of $3.5 million, of which $1.8 million, if recognized, would favorably impact the effective tax rate. Unrecognized tax benefits, inclusive of accrued interest, increased by $3.1 million as a result of the acquisition of Palomar, of which $1.6 million, if recognized, would favorably impact the effective tax rate. The $3.1 million increase in unrecognized tax benefits was recorded in purchase accounting against goodwill in the second quarter upon the acquisition of Palomar and includes $0.3 million in interest and penalties. Cynosure classifies interest and penalties related to income taxes as a component of its provision for income taxes.
	Cynosure files income tax returns in the U.S. federal jurisdiction, and in various state and foreign jurisdictions. Cynosure is no longer subject to U.S. federal income tax examinations by tax authorities for years before 2010. With few exceptions, Cynosure is no longer subject to U.S. state tax examinations for years before 2008. Additionally, certain non-U.S. jurisdictions are no longer subject to income tax examinations by tax authorities for years before 2008. Palomar’s pre-acquisition income tax filings for the years 2006 through 2012 remain open to examination by the taxation jurisdictions in which they were filed.

Commitments And Contingencies Disclosure [Abstract]	'
Contingencies	'
	Note 16 — Contingencies
	The medical device market in which Cynosure participates is largely technology-driven. As a result, intellectual property rights, particularly patents, play a significant role in product development and differentiation. However, intellectual property litigation is inherently complex and unpredictable. Furthermore, appellate courts can overturn lower court patent decisions.
	In addition, competing parties may file suits to balance risk and exposure between the parties. Adverse outcomes in proceedings against Cynosure could limit its ability to sell certain products in certain jurisdictions, or reduce operating margin on the sale of these products and could have a material adverse effect on Cynosure’s financial position, results of operations or liquidity.
	In addition, although monetary and injunctive relief is typically sought, remedies and restitution are generally not determined until the conclusion of the trial court proceedings and can be modified on appeal. Accordingly, the outcomes of individual cases are difficult to time, predict or quantify.
	Cynosure is not insured with respect to intellectual property infringement and maintains an insurance policy providing limited coverage against securities claims and product liability claims. The absence of significant third-party insurance coverage increases potential exposure to unanticipated claims or adverse decisions.
	Cynosure continually assesses litigation to determine if an unfavorable outcome would lead to a probable loss or reasonably possible loss, which could be estimated. In accordance with the FASB’s guidance on accounting for contingencies, Cynosure accrues for all direct costs associated with the estimated resolution of contingencies at the earliest date at which it is deemed probable that a liability has been incurred and the amount of such liability can be reasonably estimated. If the estimate of a probable loss is a range and no amount within the range is more likely, Cynosure accrues the minimum amount of the range. In the cases where Cynosure believes that a reasonably possible loss exists, the facts and circumstances of the litigation are disclosed, including an estimable range, if possible. In management’s opinion, Cynosure is not currently involved in any legal proceedings, which, individually or in the aggregate, could have a material effect on its financial statements. Cynosure believes that contingent losses associated with any of its current litigation were remote at the time of the filing and as such, Cynosure has not recorded or disclosed any material loss contingencies, or provided any disclosures, related to such litigation.
	Cynosure expenses patent defense costs, costs for pursuing patent infringements, and external legal costs related to intangible assets in the period in which they are incurred.

Stock-Based Compensation	'
	Option-pricing models require the input of various subjective assumptions, including the option’s expected life and the price volatility of the underlying stock. Cynosure’s estimated expected stock price volatility is based on its own historical volatility. Cynosure’s expected term of options granted during the nine months ended September 30, 2013 represents the weighted average period of time that options granted are expected to be outstanding giving consideration to vesting schedules and Cynosure’s historical exercise patterns. Cynosure’s expected term of options granted in the nine months ended September 30, 2012 was derived from the short-cut method. The risk-free rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The dividend yield of zero is based on the fact that Cynosure has never paid cash dividends and has no present intention to pay cash dividends.
Long-Lived Assets Held for Sale	'
	In accordance with ASC 360, Cynosure considers properties to be assets held for sale when all of the following criteria are met:

		•	an active program to locate a buyer and other actions required to complete the plan to sell the asset have been initiated;
		•	sale of the property is probable and Cynosure expects the completed sale will occur within one year;
