here you have 2 questions
Ans 1.Scar revision are based on types of scar. if it is superficial than go for topical treatmnets (like retinoic acids) with minor OT procedures like dermaroller
, dermabration or chemical peelings.
if scar is deep with pigmentation thn the best technique is scar revision surgeries which is done by dermatosurgeon or plastic surgeon.
scar can ne minimized or revisied, can not be removed. so now the term scar removal is replaced by revision.
Ans 2 , well the glow of skin comes from the skin colour, surface (dry, oily) and conture. a combined effort like exercise, use cleansers insteed of soaps, apply proper moisturizers and regular inspection of skin can make a healthy and young skin.
hope it will help u
