A quick primer on light therapy: red light is known to promote circulation and reduce inflammation while blue light targets acne-causing bacteria and makes oil glads produce less sebum. What this mask helped me most with was preventing new breakouts from forming on top of the cluster already invading my chin. It stopped what was previously a never-ending cycle of acne.
Best used for treating hyperpigmentation, these products — packed with glycolic acid — promote cellular turnover to remove the top layers of the skin revealing a brighter, fresh complexion, says New York City-based dermatologist Dendy Engelman. "Glycolic acid is the smallest acid in size," she says. (This means it can get deep into the skin.) "It is very effective in breaking down skin cells and removing dead particles," says Engleman. "It boosts collagen production and elastin production with the removal of waste and dead skin cells." Bottom line: By removing these dead cells, healthy, glow-y skin is revealed.
Your body is capable of taking care of your scars and they will get lighter with time. However, if you expose them to the sun, their healing process will slow down and the scars will get darker. So, avoid the sun. If it’s essential to go out in sun, use sunscreen to guard your skin and also cover yourself with hat, umbrella, clothes- whatever you can lay hands on.

Have good hygiene. There is a balance between under-washing and over-washing skin. Under-washing leaves excess skin cells, oil, bacteria, and other debris on the skin, potentially clogging pores and creating blemishes. Over-washing irritates and dries the skin, contributing to excess oil production and more breakouts. Refrain from washing problem areas more than twice a day. When washing, use gentle cleansers with smooth grains and light scrubbing to exfoliate. Avoid products containing large grains, such as almond or apricot shell fragments, that will potentially damage or irritate the skin.
Moderation and regularity are good things, but not everyone can sleep eight hours, eat three healthy meals per day, and drink plenty of water a day. Probably the most useful lifestyle changes one can make is to never to pick or squeeze pimples. Playing with or popping pimples, no matter how careful and clean one is, nearly always makes bumps stay redder and bumpier longer. People often refer to redness as "scarring," but fortunately, it usually isn't permanent. It's just a mark that takes months to fade if left entirely alone.
