  Why Your Skin Needs Extra Care After Laser Hair Removal

  Laser hair removal works by the principle of photothermolysis. It is a process in which hair follicles are treated with intense light causing damage to the hair follicles thus limiting growth of more hair. This is not just limited to the hair follicle being targetted but also on the skin surrounding it and, as a result, it becomes sensitive for a while. After the treatment is completed, your skin is likely to look warm, slightly red or even tender at times.

  In this state, your skin becomes delicate and sensitive to external stimuli – most specifically the sun. Also, the UV rays in the sun will try to exacerbate any post-laser sensitivity and cause side effects such as darkening of the sensitive area, inflammation, and even burns. This is where sunscreen comes in handy as one of the best lines of protection.

Applying sunscreen regularly will help to lower this risk hence enabling your skin to regain its normal color and texture.

Over a certain period, this may contribute to premature aging signs, such as fine lines, wrinkles, and skin laxity.
