                                 RE: PHOTOMEDEX, INC.

Gentlemen:

      We have acted as counsel for PhotoMedex, Inc., a Delaware corporation (the
"Company"), in connection with the preparation and filing with the Securities
and Exchange Commission, under the Securities Act of 1933, as amended (the
"Securities Act"), of a Registration Statement on Form S-3 (the "Registration
Statement"). The Registration Statement relates to the offer and sale by the
selling stockholders named in the Registration Statement (the "Selling
Stockholders"), of up to 6,300,893 shares (the "Shares") of common stock, par
value $0.01, of the Company.

      In acting as counsel to the Company, we have examined originals or copies,
certified to our satisfaction, of such documents, corporate records and other
instruments, as we have deemed necessary. In addition, we have examined such
books and records of the Company, as in our judgment, is necessary or
appropriate to enable us to render the opinions expressed below.

      We assume for purposes of this opinion that the Shares, which are issuable
upon exercise of the warrants (as such terms are described in the Registration
Statement) of the Company will be issued in compliance with the Company's
Certificate of Incorporation and the terms and conditions of the warrants.

      We are opining herein only as to the effect of the federal laws of the
United States, the internal laws of the State of California and the General
Corporation Law of the State of Delaware, and we express no opinion with respect
to the applicability thereto, or the effect thereon, of the laws of any other
jurisdiction, or in the case of the State of Delaware, any other laws, including
without limitation, any matters of municipal law or the laws of any other local
agencies within the State of Delaware.

      Based upon the foregoing, it is our opinion that the Shares, when issued
to and sold by the Selling Stockholders in the manner contemplated by the
Prospectus, which forms a part of the Registration Statement, and in conformity
with the Certificate of Incorporation of the Company, as amended and restated
and in effect as of the date hereof, will be legally and validly issued, fully
paid and non-assessable.

      We consent to the use of this opinion as an exhibit to the Registration
Statement and the use of our name in the Registration Statement and the
Prospectus. By giving you this opinion and consent, we do not admit that we are
experts with respect to any part of the Registration Statement or the
Prospectus, within the meaning of the term "expert," as used in Section 11 of
the Securities Act, or the rules and regulations promulgated thereunder, nor do
we admit that we are in the category of persons whose consent is required under
Section 7 of the Securities Act, or the rules and regulations promulgated
thereunder.



                                    Very truly yours,



                                    LUCE, FORWARD, HAMILTON & SCRIPPS LLP
