Recent studies have demonstrated the potency of topical tretinoin in the treatment of photoaging. The cosmetic regimen was significantly better tolerated than tretinoin through 8 weeks by all measures.Īn appropriately designed cosmetic regimen can improve facial wrinkle appearance comparably with the benchmark prescription treatment, with improved tolerability.Īging, an inevitable and continuous process in one's lifetime, has all along been a focus of interest, especially for women, yet photoaging treatment to slow the process remains challenging.

The cosmetic regimen significantly improved wrinkle appearance after 8 weeks relative to tretinoin, with comparable benefits after 24 weeks.

Product tolerance was assessed via clinical erythema and dryness grading, subject self-assessment, and determinations of skin barrier integrity (transepidermal water loss) and stratum corneum protein changes. Changes in facial wrinkling were assessed by both expert grading and image analysis of digital images of subjects' faces and by self-assessment questionnaire. Subject cohorts (n = 25) continued treatment for an additional 16 weeks.

Subjects on the prescription regimen (n = 97) used 0.02% tretinoin plus moisturizing SPF 30 sunscreen. Following 2 weeks washout, subjects on the cosmetic regimen (n = 99) used a sun protection factor (SPF) 30 moisturizing lotion containing 5% niacinamide, peptides and antioxidants, a moisturizing cream containing niacinamide and peptides, and a targeted wrinkle product containing niacinamide, peptides and 0.3% retinyl propionate. a prescription regimen with 0.02% tretinoin for improving the appearance of facial wrinkles.Īn 8-week, randomized, parallel-group study was conducted in 196 women with moderate to moderately severe periorbital wrinkles. To compare the efficacy of a cosmetic moisturizer regimen vs. In contrast, cosmetic antiwrinkle products are well tolerated but are generally presumed to be less efficacious than tretinoin. Tretinoin is considered the benchmark prescription topical therapy for improving fine facial wrinkles, but skin tolerance issues can affect patient compliance. In addition only isotretinoin treatment enhanced horny layer thickness when compared to the gel cream treatment. However isomerism influenced skin effects since isotretinoin had more pronounced effects than tretinoin in viable epidermis. Our results showed that tretinoin and isotretinoin were effective in the enhancement of viable epidermis thickness and number of epidermal cell layers, suggesting that they could be used for stimulation of cellular renewal. Histopathological evaluation, viable epidermal and horny layer thicknesses as well as the number of epidermal cell layers were determined. For this, gel cream formulations containing or not 0.05% tretinoin or 0.05% isotretinoin were applied in the dorsum of hairless mice, once a day for seven days. Thus, the aim of this study was to compare the effects of topical use of tretinoin or isotretinoin on hairless mice epidermis, using appropriate histopathological and histometric techniques, in order to evaluate the influence of isomerism on skin effects. Since isotretinoin topical treatment usually shows much lower incidence and intensity of adverse effects than tretinoin topical treatment, histological studies are needed to scientifically evaluate the effects of isotretinoin application on epidermis and also to assess if it can be used in anti-aging products as an alternative to tretinoin. The efficacy of tretinoin is well established in the treatment of acne and photoaged skin, however as a typical side effect of tretinoin treatment most patients develop a low-grade irritant dermatitis.

Both studies demonstrated that tretinoin cream 0.02% is safe and effective for the treatment of moderate-to-severe photodamaged facial skin. Therapy with tretinoin cream 0.02% was well tolerated overall and demonstrated a favorable safety profile. Results indicate statistically significant improvement in fine wrinkling, coarse wrinkling, and yellowing with the use of tretinoin cream 0.02% at week-24 end point, compared with placebo. Two multicenter, randomized, double-blind, vehicle-controlled clinical., studies were conducted to evaluate the safety and efficacy of the lower concentration tretinoin formulation in the treatment of moderate-to-severe facial photodamage. To provide additional prescribing flexibility for various patient needs, a new lower concentration formulation, tretinoin cream 0.02% was chosen for further development. In extensive clinical studies and practical use since its US Food and Drug Administration approval in 1995, tretinoin emollient cream 0.05% has been shown to be safe and effective in the treatment of fine facial wrinkles, mottled hyperpigmentation, and skin roughness.
