The popularity and efficacy of retinoids, particularly compounds like retinol and tretinoin, in the aesthetics industry can be attributed to their remarkable ability to influence various cellular processes in skin. Vitamin A, the parent compound of these retinoids, has maintained its prominence for decades due to its multifaceted benefits.

THE YIN & YANG OF RETINOL

Retinoids play a crucial role in skin care by increasing cellular turnover, regulating sebum production, reducing bacteria in follicles, and stimulating fibroblast activity to promote neocollagenesis. These actions make retinoids highly effective in addressing aging, hyperpigmentation, and acne, leading to their widespread adoption among both skin care professionals and consumers.

However, despite their numerous benefits, retinoids can also cause significant side effects if not used properly. Their stimulatory effects may trigger the body’s inflammatory response, resulting in erythema, dryness, and sensitivity, which, if left uncontrolled, can progress to hyperpigmentation and post-inflammatory pigmentation. Moreover, inadequate sun protection can exacerbate these issues.
