Vitamin A, also known as retinol or retinoids, has been the go-to compound for many dermatologists and skincare specialists when clients want smoother, clearer skin-and for good reason. There is increasing evidence of its effectiveness.

A recent study involved the application of a 0.4% retinol lotion on the upper, inner arm skin of about 30 elderly people. Before the initial application and then several times over the course of 24 weeks, researchers evaluated the wrinkles and roughness of the participants’ skin, ranking the aged appearance on a severity scale of zero to nine.

At the end of the study, it was apparent that skin texture was markedly improved. Furthermore, biopsies showed that the retinol had increased collagen and glycosaminoglycan.

“Topical retinol improves fine wrinkles associated with natural aging,” the study authors deduced. “Significant induction of glycosaminoglycan, which is known to retain substantial water, and increased collagen production are most likely responsible for wrinkle effacement.”
