Retinol is a derivative of Vitamin A (retinoic acid) that is widely recommended by dermatologists. In La Roche-Posay formulas, retinol helps promote surface cell turnover and improve the appearance of fine lines and wrinkles. La Roche-Posay's Retinol B3 Serum combines pure retinol with vitamin B3 to reduce the appearance of fine lines and wrinkles and reduce premature sun damage.

We do not have a minimum age requirement for our La Roche Posay Retinol B3 Serum. However, we recommend consulting with your dermatologist prior to make sure it will work for you.

No, it's not recommended to use retinol during the daytime. Retinol can increase skin sensitivity to sunlight, so it's best used at night. Always use sunscreen in the morning to protect your skin, especially if you are using retinol regularly in your nightly routine.
