Hi JL. Retin A is designed to remove the outer layers of dead skin (stratum corneum). From the perspective of skin health, Retin A is great because it makes your skin appear softer, healthier and fresher. It gives the skin a workout because the epidermis reproduces more quickly when using Retin A.With that said, removing this protective outer layer of dead skin cells makes you much more vulnerable to sunlight and the light that's found in IPL treatments. For this reason, we recommend that our patients take at least 7 days off Retin A before undergoing any laser treatments. You can have the treatments, but the risk of side effects is higher while using Retin A and most practitioners will ask that you stay off it for some period of time before laser treatments.
