What is one potential effect of using products containing retinol?

Using products containing retinol can lead to higher sun sensitivity. Retinol, a derivative of vitamin A, works by promoting cell turnover and encouraging the production of new skin cells. This process can thin the outer layer of the skin temporarily, making it more susceptible to UV radiation. Therefore, individuals using retinol products are often advised to apply sunscreen regularly and take additional precautions when exposed to sunlight to minimize the risk of sunburn and other sun-related skin issues.

Other potential effects of retinol, such as improvements in acne control, can occur, but they do not necessarily contribute to an increased risk of sensitivity to the sun. The mechanism of retinol makes sun sensitivity a significant consideration for users.
