Subtle redness and tingling are normal after use (don’t worry, it will subside pretty quickly) but, that being said, every skin’s tolerance level is different. If you’re uber-sensitive—especially to acids or vitamin C—Doctor’s Visit may not be the right choice for you.
If you’re unsure, start with a patch test; apply a small amount of product to your neck and leave it on for one minute. If you notice any intense burning or itching, discontinue use and try our Overnight Facial instead, which delivers similar results but is gentle enough for sensitive skin.
