Stock-Based Compensation	'
	Note 2 — Stock-Based Compensation
	Cynosure recorded stock-based compensation expense of $1.5 million and $0.8 million for the three months ended March 31, 2014 and 2013, respectively. As of March 31, 2014 and 2013, respectively, Cynosure had $25,000 and $19,000 of stock-based compensation expense capitalized as a part of inventory.
	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 share-based payments, as follows:
		Three Months
		Ended March 31,
		2014			2013
		(In thousands)
	Cost of revenues	$	65		$	36
	Sales and marketing		443			240
	Research and development		228			141
	General and administrative		730			422
	Total stock-based compensation expense	$	1,466		$	839
	Cash received from option exercises was $7.3 million and $0.5 million during the three months ended March 31, 2014 and 2013, respectively.
	Cynosure granted 657,240 and 284,200 stock options during the three months ended March 31, 2014 and 2013, respectively. Cynosure utilizes the Black-Scholes model to determine the weighted average fair value of options. The weighted average fair value of the options granted during the three months ended March 31, 2014 and 2013 was $11.23 and $13.47, respectively, using the following assumptions:
		Three Months Ended
		March 31,
		2014		2013
	Risk-free interest rate	1.44% - 1.76%		0.79% - 0.92%
	Expected dividend yield	—		—
	Expected term	4.6 years		4.8 years
	Expected volatility	43% - 44%		56%
	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 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. 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.
	Cynosure granted 44,840 restricted stock units during the three months ended March 31, 2014 to employees at a fair market value of its common stock on the date of grant and which vest quarterly over a three-year period. Cynosure is recognizing related compensation expense on a straight-line basis over the three-year period.

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 March 31, 2014 (in thousands):
			Level 1		Level 2		Level 3		Total

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 first quarter of 2014, Cynosure revised its estimates of the assets acquired and liabilities assumed in regards to the acquisition of Palomar, and as a result, increased goodwill $115,000 from December 31, 2013 to March 31, 2014, due primarily to a reclassification of certain tax reserves, adjustments to the inventory reserve and write downs of accruals related to the opening balance sheet.
	The allocation of the acquisition purchase price is subject to adjustment upon finalization of the fair value procedures, and therefore the current measurements of inventory, intangible assets acquired, goodwill, accrued warranty and deferred tax assets and liabilities (including uncertain tax positions) are subject to change.
	The following table summarizes the 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	)

Net Income Per Common Share	'
	Note 10 — Net Income Per Common Share
	Basic net income per share is determined by dividing net income by the weighted average common shares outstanding during the period. Diluted net income per share is determined by dividing net 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 and restricted stock units based on the treasury stock method. For the three months ended March 31, 2014 and 2013, there are no outstanding Class B shares, and Cynosure may not issue Class B shares in the future.
	A reconciliation of basic and diluted shares is as follows (in thousands, except per share data):
		Three Months Ended

	For the three months ended March 31, 2014 and 2013, approximately 1.1 million and 0.4 million, respectively, weighted average stock options and restricted stock units to purchase shares of the Company’s Class A common stock were excluded from the calculation of diluted weighted average common shares outstanding as their effect was antidilutive.

Income Taxes	'
	Note 13 — Income Taxes
	During each of the three months ended March 31, 2014 and 2013, Cynosure recorded an income tax provision of $0.4 million. The income tax provision for the three months ended March 31, 2014 is primarily attributable to the tax provision on the earnings of its foreign and domestic operations.
	At December 31, 2013, Cynosure had gross tax-effected unrecognized tax benefits of $1.7 million, of which $0.1 million, if recognized, would favorably impact the effective tax rate. During the three months ended March 31, 2014, Cynosure recorded an immaterial amount of interest and penalties on the previously recorded unrecognized tax benefits. Cynosure classifies interest and penalties related to income taxes as a component of its provision for income taxes. Cynosure does not expect any material changes in the amounts of unrecognized tax benefits over the next 12 months.
	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 2009.

	Lease Commitments
	On November 18, 2013, Cynosure entered into the Lease Amendment related to its headquarters located at 5 Carlisle Road, Westford, MA. Pursuant to the Lease Amendment, the term of the Lease has been extended to May 2027 (with two five-year extension options) and the leased premises have been expanded to include additional space at the current location as well as space in the adjacent building, 3 Carlisle Road, Westford, MA. Under the terms of the Lease Amendment, the base rent under the Lease will be abated for a 21-month period beginning in May 2014, and Cynosure will have rights to lease additional space at 3 Carlisle Road.
	ASC 840, Leases, establishes the framework for accounting for the Amendment. In accordance with ASC 840, Cynosure is accounting for the land portion of the leased premises as an operating lease. The buildings at 5 Carlisle Road and 3 Carlisle Road have met the criteria for capital lease accounting under ASC 840-10-25-1, and thus Cynosure is accounting for the buildings portion of the leased premises as capital leases and incurring interest charges accordingly. The interest rates used for the 5 Carlisle Road and 3 Carlisle Road capital leases are 10.8% and 8.8%, respectively. The expansion of the leased premises, and the improvements to the leased premises, are recorded on the balance sheet as leasehold improvements within property, plant and equipment. Assets under capital leases and leasehold improvements related to the Amendment are amortized using the straight-line method over the respective lease term.
	Cynosure leases the land portion of its U.S. operating facility and certain foreign facilities under non-cancelable operating lease agreements expiring through May 2027. These leases are non-cancellable and typically contain renewal options. Certain leases contain rent escalation clauses for which Cynosure recognizes the expense on a straight-line basis. Rent expense for the three months ended March 31, 2014 was approximately $1.0 million.
	Cynosure leases the buildings portion of its U.S. operating facility and certain equipment and vehicles under capital lease agreements with payments due through May 2027. Commitments under Cynosure’s lease arrangements are as follows, in thousands:
