         MEDICIS REPORTS SECOND QUARTER FISCAL 2005 FINANCIAL RESULTS;

        31% Increase in Revenues and 50% Increase in Earnings Per Share,
                             Absent Special Charges

SCOTTSDALE, Arizona--January 20, 2005--Medicis (NYSE:MRX) today announced second
quarter  fiscal 2005 net revenue  growth of  approximately  31% to $92.3 million
with  "if-converted"  net income of $25.4  million,  or $0.36 per diluted share,
absent a $3.5 million tax-effected special charge associated with a research and
development  collaboration,  compared to second quarter fiscal 2004 net revenues
of $70.6 million with  "if-converted" net income of $16.9 million,  or $0.24 per
diluted share, absent a $1.6 million tax-effected special charge associated with
a research and development  collaboration.  Including the  tax-effected  special
charge of $3.5  million,  the Company  reported  Generally  Accepted  Accounting
Principles  ("GAAP") net income of $20.2 million, or $0.31 per diluted share for
the second quarter of fiscal 2005.  Including the tax-effected special charge of
$1.6 million,  the Company  reported GAAP net income of $13.6 million,  or $0.21
per  diluted  share for the second  quarter of fiscal  2004.  Diluted  per share
amounts  are  calculated  using  the  "if-converted"  method  of  accounting  in
accordance with GAAP.

Second quarter fiscal 2005 net revenues increased  primarily due to RESTYLANE(R)
and  PLEXION(R).  At the end of the second  quarter,  the Company's  core brands
included  RESTYLANE(R),   DYNACIN(R),   LOPROX(R),  OMNICEF(R),  PLEXION(R)  and
TRIAZ(R).  For the second  quarter of fiscal  2005,  the  Company's  core brands
represented  approximately  78% of total  revenue.  Additionally,  the Company's
gross profit margin for second quarter  fiscal 2005  increased to  approximately
85% from approximately 84% over the prior year.

For the first six months of fiscal 2005,  Medicis reported net revenue growth of
approximately  35% to $181.2  million  with  "if-converted"  net income of $47.4
million, or $0.66 per diluted share, absent a $19.4 million tax-effected special
charge associated with the SubQ(TM) transaction reported in the first quarter of
fiscal 2005 and absent a $3.5 million  tax-effected  special  charge  associated
with a research and development  collaboration with Ansata Therapeutics reported
in second quarter fiscal 2005.  Including the  tax-effected  special  charges of
$22.9 million  reported in the first half of fiscal 2005,  Medicis  reported net
income of $21.2 million,  or $0.34 per diluted share for the first six months of
fiscal 2005.

For the first six months of fiscal 2004, Medicis reported net revenues of $133.9
million with  "if-converted"  net income of $29.0 million,  or $0.41 per diluted
share,  absent a $37.5  million  tax-effected  loss  associated  with the  early
extinguishment of debt reported in the first quarter of fiscal 2004 and absent a
$1.6  million  tax-effected  special  charge  associated  with  a  research  and
development  collaboration reported in second quarter fiscal 2004. Including the
tax-effected  special charges of $37.5 million and $1.6 million  reported in the
first half of fiscal  2004,  Medicis  reported a net loss of $13.5  million,  or
$(0.25) per diluted share for the first six months of fiscal 2004.

The 35%  increase  in net  revenues  for the first six months of fiscal 2005 was
primarily attributable to growth in the RESTYLANE(R),  DYNACIN(R) and PLEXION(R)
brands. In the first half of fiscal 2005, the Company's core brands  represented
approximately 77% of total revenue. Additionally, the Company's gross profit

                                     (more)



margin for the first half of fiscal 2005 increased to approximately 85% from 84%
over the prior year.

Selling,  general and administrative expenses in second quarter fiscal 2005 were
$32.3 million,  or approximately 35% of revenues  compared to $29.1 million,  or
approximately 41% of revenues in the second quarter fiscal 2004, a decrease as a
percentage of revenues of  approximately 6 percentage  points.  The $3.2 million
increase in selling,  general and  administrative  expenses primarily was due to
incremental  costs associated with  RESTYLANE(R).  The decrease in percentage of
revenues  primarily was due to second quarter fiscal 2005 revenues outpacing the
increase in selling, general and administrative spending.

Research  and  development  expenses  for the  second  quarter  of  fiscal  2005
increased  approximately  31% to $4.4 million,  or approximately 5% of revenues,
absent  special  charges,  compared  to $3.3  million,  or  approximately  5% of
revenues, in second quarter fiscal 2004.

"We are  pleased  to  announce a solid  second  quarter,"  said Jonah  Shacknai,
Chairman  and  Chief  Executive   Officer  of  Medicis.   "Continued  growth  of
RESTYLANE(R),  LOPROX(R) Shampoo and DYNACIN(R) Tablets highlighted the quarter,
along with the introduction of our innovative  PLEXION(R)  Cleansing  Cloths. We
were  delighted  to enter into a research  and  development  collaboration  with
Ansata Therapeutics for a unique peptide technology. As we enter the second half
of fiscal 2005, we anticipate  continuation  of our  `emergence'  theme with the
goal of  introducing  at least one new product  from our  vigorous  research and
development  pipeline.  Our  commitment to  shareholder  value,  physicians  and
patients remains resolute."

In second quarter fiscal 2005,  approximately  $84 million of common shares were
repurchased  under the stock repurchase  program approved by the Company's Board
of  Directors  in August 2004  (2,177,286  shares at an average  market price of
$38.65). As of December 31, 2004, the repurchase  authorization  amount of up to
$150 million in common stock under the new program has been met.

Medicis   previously   released   updated   fiscal  2005  revenue   guidance  of
approximately $375 million and earnings per share guidance of $1.42. The Company
is  raising  its  previous  fiscal  2005  revenue  guidance  by  $1  million  to
approximately  $376 million,  and earnings per share guidance by $0.01 to $1.43,
excluding  special charges.  Based upon information  available  currently to the
Company and as a result of the second quarter fiscal 2005 results, the Company's

At its June 30-July 1, 2004  meeting,  the Emerging  Issues Task Force  ("EITF")
began discussing Issue 04-8,  "Accounting  Issues Related to Certain Features of
Contingently Convertible Debt and the Effect on Diluted Earnings per Share," and
the accounting for contingently convertible debt instruments,  commonly referred
to as "CoCos." At its subsequent September 29-30, 2004 meeting, the EITF reached
a  conclusion  that  CoCos  should be  included  in diluted  earnings  per share
computations  (if  dilutive)  regardless of whether the market price trigger has
been met, effective for periods ending after December 15, 2004.

As a result of the EITF's  conclusion,  second  quarter  fiscal  2005 and second
quarter fiscal 2004 diluted per share amounts and year-to-date diluted per share
amounts  are  calculated  using  the  "if-converted"  method  of  accounting  in
accordance  with GAAP  regardless of whether the  outstanding  2.5%  Convertible
Senior Notes and 1.5% Convertible  Senior Notes meet the criteria for conversion
and  regardless  of whether the  bondholders  actually  convert their bonds into
shares.  For second  quarter fiscal 2004,  the dilutive  shares  relative to the
convertible   notes  do  not  impact  GAAP  earnings  per  share,  as  they  are
anti-dilutive.

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 and other filed  documents  with the  Securities  and
Exchange  Commission.  At the time of this release,  the Company  cannot,  among
other  things,  assess 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, 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,  in
particular,  the recent approval of a generic LOPROX(R) Cream or a substitutable
DYNACIN(R) Tablet form, 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,  nor if any payments such as these will be made at all. The above
estimated  future  guidance does not include the potential  payments  associated
with any such transactions.

in the  circumstances.  Such  statements are subject to a number of assumptions,
risks and  uncertainties,  many of which are beyond the control of Medicis.  Any

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 transactions,  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,  the risks of  pending or future  litigation,  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, 2004.  There can be no assurance
