Which products are known to increase sensitivity to sunlight?

Retinol is known to increase sensitivity to sunlight due to its potency as a derivative of vitamin A. It works by promoting cell turnover and exfoliation, which can lead to increased vulnerability of the skin, especially to UV radiation. When using retinol, the outer layer of the skin is often thinner and more delicate, making it more susceptible to sun damage. Consequently, it is generally recommended that individuals using retinol should take extra precautions to protect their skin from the sun, such as applying broad-spectrum sunscreen and wearing protective clothing.

Moisturizers, sunscreens, and antioxidants typically do not increase sunlight sensitivity; instead, they serve to hydrate the skin, protect against sun exposure, and neutralize free radicals respectively. Therefore, when considering products that may heighten sensitivity, retinol stands out as the clear choice. This is crucial knowledge for skincare specialists, as they must guide clients effectively on product usage, especially concerning sun protection.
