What is a common side effect of using retinoids?

Using retinoids often leads to skin peeling and dryness due to their action on the skin's cellular turnover process. Retinoids, derivatives of vitamin A, promote the shedding of dead skin cells and stimulate the production of new cells. This rapid cycling can result in an initial period where the skin may become irritated, leading to symptoms such as flaking, redness, and dryness, particularly in individuals who are beginning treatment or using higher concentrations.

This effect is generally expected, especially during the first few weeks of use, and can be managed by introducing the product gradually and using accompanying hydrating products. While other side effects can occur, such as oiliness from other products or allergic reactions, the peeling and dryness is the most widely reported and characteristic response to retinoid use. Understanding this common side effect helps practitioners provide better advice on product use and care routines for their clients.
