Hmm, I don't know if HRT would have any effects in the reduction of wrinkles.
Wrinkles apear when you stop producing collagen.
http://www.ncbi.nlm.nih.gov/pubmed/18794456"Two-week topical estradiol treatment stimulates collagen production in sun-protected hip skin, but not in photoaged forearm or face skin, in postmenopausal women and aged-matched men. These findings suggest that menopause-associated estrogen decline is involved in reduced collagen production in sun-protected skin. Interestingly, alterations induced by long-term sun exposure hinder the ability of topical 2-week estradiol to stimulate collagen production in aged skin."
http://www.ncbi.nlm.nih.gov/pubmed/17653955"Estrogens have a profound influence on skin. The relative hypoestrogenism that accompanies menopause exacerbates the deleterious effects of both intrinsic and environmental aging. Estrogens prevent skin aging. They increase skin thickness and improve skin moisture. Beneficial effects of hormone replacement therapy (HRT) on skin aging have been well documented"
http://www.ncbi.nlm.nih.gov/pubmed/17194967"Estrogen treatment in post menopausal women has been shown to increase collagen content, dermal thickness and elasticity. Biophysical properties are also significantly improved for the parameters reflecting hydration and sebum secretion."
http://www.ncbi.nlm.nih.gov/pubmed/16797821"Our data suggested that topical estrogen associated to systemic estrogen therapy seems to increase the expression of skin collagen amount, which may prove to be beneficial for the postmenopausal facial skin."
http://www.ncbi.nlm.nih.gov/pubmed/10656502"Our data suggest that the decrease of skin collagen is an estrogen-related phenomenon."
http://www.ncbi.nlm.nih.gov/pubmed/15507111"The skin is a target organ for various hormones, and sex steroids have a profound influence on the aging process. A decrease in sex steroids thus induces a reduction of those skin functions that are under hormonal control. Keratinocytes, Langerhans' cells, melanocytes, sebaceous glands, collagen content and the synthesis of hyaluronic acid, for example, are under hormonal influence. Topical application of estrogens has a positive effect on skin aging parameters, whilst numerous studies have also shown the positive influence of systemic hormone replacement therapy on skin aging."
http://www.ncbi.nlm.nih.gov/pubmed/6416400"The implication of this finding is that oestrogen or testosterone, or both, prevents the decrease in skin collagen content that occurs with aging and protects skin in the same way as it protects bone in postmenopausal women."
And on and on...I have full studies explaining it in more detail. I think it's pretty unequivocal. But, sun damaged skin is less likely to recuperate.

p.s.: risks mentioned in studies, associated with estrogen are those found with
non bio-identical estrogen, not bio-identical.
