                     MEDICIS ANNOUNCES FISCAL 2005 GUIDANCE

SCOTTSDALE,  Arizona--June 21, 2004--Medicis  (NYSE:MRX) today announced revenue
and earnings  guidance for Fiscal 2005. The Company's 2005 fiscal year begins on
July 1,  2004.  The  Company  will not be hosting a  conference  call to discuss
Fiscal 2005 guidance.

In assessing the Company's financial guidance, many factors and assumptions were
taken into consideration,  including,  but not limited to, current and projected
prescription  information;  sales  trend  data  of  the  Company's  RESTYLANE(R)
product;  the  generic  or  potential  generic  availability  of  the  Company's
products;  competitive threats to the Company's  products;  size, reach and call
frequency of the Company's selling organization;  status, timing and progression
of the Company's development projects;  current and projected spending levels to
support   sales,   marketing,    development,    administrative   and   customer
responsiveness  activities  and other risk factors  discussed  in the  Company's
publicly filed documents.  Based upon information  available at the time of this
release and the assumptions derived from that information,  the Company's Fiscal
2005 guidance is as follows:


                                                     Fiscal Year 2005
                                                    ending June 30, 2005



                                    First Quarter       Second Quarter     Third Quarter       Fourth Quarter       Fiscal Year
                                     (9/30/04)           (12/31/04)         (3/31/05)           (6/30/05)               2005
                                     ---------           ----------         ---------           ---------               ----
                                                                                                      
Estimated revenue objectives         $85 million         $89 million        $93 million         $98 million          $365 million
Estimated diluted EPS
 objectives                            $0.29               $0.35              $0.36               $0.42                 $1.42


"We are pleased with the launch of  RESTYLANE(R)  to date and  encouraged by the
positive response by physicians and patients," said Jonah Shacknai, Chairman and
Chief  Executive  Officer  of  Medicis.  "Mirroring  the  market  experience  in
countries  where it has been used since 1996,  RESTYLANE(R)  quickly is becoming
the  preferred  dermal  filler  among  physicians  and  patients  in the U.S. We
continue to be encouraged  by the growth of several of the  Company's  important
products and the progression of our research pipeline through the various stages
of  development.  We look  forward to  launching  several new products in coming
years to  enhance  our  already  broad  range of  dermatological  and  aesthetic
products."

The  Company  will  continue  to focus  its  efforts  largely  on  opportunities
associated  with   RESTYLANE(R).   The  Company  expects  revenues  to  grow  at
approximately  21% to $365  million  with  RESTYLANE(R)  as its  primary  growth
driver.  Included  in the  revenue  guidance  is  approximately  $50  million of
contract revenue associated with

                                     (more)


the out licensing of ORAPRED(R)  recognized  evenly  throughout the fiscal year.
The Company has made certain  assumptions  regarding generic  competition to its
DYNACIN(R)  Tablets  and  LOPROX(R)  Cream  products.  The  timing  of a generic
approval,  its launch and its generic  erosion  rates could affect the Company's
revenue estimates.

Medicis  anticipates  Fiscal 2005 gross profit margins of  approximately  85% of
total revenues,  operating income margins to increase to approximately  40%, and
net income margins to increase to  approximately  25%,  resulting in anticipated
net income growth of  approximately  35%. Diluted earnings per share is expected
to increase by approximately 26% in Fiscal 2005. The Fiscal 2005 and Fiscal 2004
diluted  earnings  per share  figures are  calculated  using the  "if-converted"
method of accounting in accordance with Generally Accepted Accounting Principles
due to the  Company's  outstanding  2.5%  Convertible  Senior Notes  meeting the
criteria for conversion.

Selling,  general and  administrative  expenses are expected to be approximately
35% as a  percentage  of sales,  representing  as a  percentage  of  revenues an
approximately  3-percentage  point  decline for Fiscal 2005.  Included in Fiscal
2005  selling,   general  and  administrative   expenses  are  the  addition  of
approximately  15  sales  representatives  primarily  to  promote  RESTYLANE(R),
enhanced  promotion  of  RESTYLANE(R),  and  continued  investment  in physician
training.  Research and development  expenses for Fiscal 2005 are expected to be
approximately 4% of total revenues,  and depreciation and amortization  expenses
are expected to be  approximately  $21 million for the fiscal year primarily due
to  the   amortization  of  payments  to  Q-Med  relating  to  the  RESTYLANE(R)
acquisition.  The Company's  effective tax rate is expected to be  approximately
36%. Weighted average diluted shares  outstanding for Fiscal 2005 is expected to
be  approximately  68 to 69 million shares,  but is dependent upon the Company's
stock price in any given quarter.

The Company is planning on launching several new marketing  campaigns as well as
training  and hiring new sales  representatives  as early in the fiscal  year as
practicable.  As a result,  operating income and net income margins are expected
to be lowest in the first  quarter  of Fiscal  2005 and  highest  in the  fourth
quarter  of  Fiscal  2005,  as the  Company  will  derive  the  benefit  of such
investments in the later part of the fiscal year.

The above guidance does not include  conversion of the Company's 1.5% Contingent
Convertible  Senior Notes due 2033, the effect of expensing  stock options,  and
the  potential  impact of other  components of the  Company's  growth  strategy,
including   possible  future   acquisitions  of  products,   businesses   and/or
technologies  and the  launch of new  products  from the  Company's  development
pipeline.

At the time of this disclosure, Medicis believes these objectives are attainable
based  upon  information  currently  available  to the  Company.  The  Company's
business is subject to all risk factors  outlined in the  Company's  most recent
annual report on Form 10-K, its Form S-3 registration  statement and other filed
documents  with the  Securities  and  Exchange  Commission.  At the time of this
release,  the  Company  cannot,  among  other  things,  assess the impact of any
pending or future litigation  matters,  the forthcoming results of the Company's
research and development projects and the risks associated with the FDA approval
process,  risks  associated with  significant  competition  within the Company's
industry,  risks  associated with changes in laws, the risks associated with the
credit risk of BioMarin to derive the Company's contract revenue,  risks related
to general economic  conditions,  including interest rate fluctuations,  nor can
the Company  validate its  assumptions of the full impact on its business of the
approval of competitive  generic  versions of the Company's core brands,  or any
future  competitive  product  approvals  that may affect the  Company's  brands.
Additionally,  Medicis may acquire and/or license products or technologies  from
third  parties to enter into new  strategic  markets.  The Company  periodically
makes  up-front,  non-refundable  payments  to third  parties for  research  and
development  work which has been  completed and  periodically  makes  additional
non-refundable payments for the achievement of various milestones.  There can be
no certainty  which periods these  potential  payments  could be made, or if any
payments such as these will be made at all. The stated estimated future guidance
does not include the potential payments associated with any such transactions.

United  States  focusing  primarily  on  the  treatment  of  dermatological  and

statements"  within the meaning of the  Securities  Litigation  Reform Act.  All
statements  included in this press  release that address  activities,  events or
developments that Medicis expects,  believes or anticipates will or may occur in
the future are  forward-looking  statements.  This includes earnings  estimates,
future  financial  performance and other matters.  These statements are based on
certain  assumptions  made by Medicis based on its  experience and perception of

current   views  of  Medicis  with  respect  to  future   events  and  financial
performance.  No assurances can be given,  however, that these events will occur

of the full  impact on its  business  of the  approval  of  competitive  generic
versions of its core brands,  including DYNACIN(R) Tablets and/or LOPROX(R),  or
any future competitive product approvals that may affect its brands. Also, there
are a number of additional  important factors that could cause actual results to
differ  materially from those  projected,  including the anticipated size of the
markets,  the availability of product supply, the receipt of required regulatory
approvals,  the ability to realize  anticipated  synergies  and  benefits of the
Q-Med  transaction,  the  risks  and  uncertainties  normally  incident  to  the
pharmaceutical industry, dependence on sales of key products, the uncertainty of
future financial  results and fluctuations in operating  results,  dependence on
Medicis'  strategy  including the  uncertainty of license  payments and/or other
payments  due  from  third  parties,  the  timing  and  success  of new  product
development by Medicis or third parties,  product  introductions and other risks
described from time to time in Medicis' SEC filings  including its Annual Report
on Form 10-K for the year ended June 30,  2003.  There can be no assurance as to
when or if any of the  holders of the Notes will have the right to convert or if
the Notes  will be  converted,  and what  impact the  increase  in the number of
shares  outstanding  will have on its  results  of  operations.  Forward-looking
statements  represent the judgment of Medicis' management as of the date of this
release,   and  Medicis  disclaims  any  intent  or  obligation  to  update  any
