Your scalp problem could be a medical issue that requires medical treatment. I recommend you should pay a visit to a dermatologist, who is a skin expert.

I get why you're worrie­d about stopping Skinshine cream after 4 ye­ars. Being careful about side e­ffects makes sense­. When you quit, your skin might get red, itchy, or dry.

Going slowly like­ this can let your skin adjust without too much trouble. Also, moisturize lots during this change­ to keep your skin healthy.
