Poly (lactic-co-glycolic acid) (PLGA) is a kind of medical polymer material with good biodegradability and histocompatibility, which widely used in postoperative anti-adhesion materials. In this paper, PLGA microfiber membrane was successfully prepared poly(lactic-co-glycolic as the main by electrospinning technology. The surface morphology, wettability, dimensional stability mechanical propert...

α-Hydroxy acid (AHA) formulations are commonly used for skin chemical peelings. The primary target is the stratum corneum (SC). The aim of this study was to assess the effects of various glycolic acid concentrations and commercial phenolic acid formulations on the SC. Quantitative colorimetry of a corneoxenometry bioassay was used. The test procedure involved glycolic acid concentrations rangin...

Topically applied tretinoin (a retinoid) has been used for over 25 years to treat acne and disorders of keratinization. Now, tretinoin emollient cream, 0.05% (Renova®), may be prescribed for the treatment of photodamaged and chronologically aged skin, in conjunction with appropriate skin care and sun protection routines. Mild to moderate cutaneous side effects to topical tretinoin, such as xero...

This article summarizes the antiaging properties of retinoids, glycolic acid, ascorbic acid, and peptide topicals. The supporting evidence is taken from the literature and the primary author's research, consisting of previously published data and new results from ongoing projects.
