Blue light therapy is perhaps a more advanced form of light therapy and works great in alleviating acne scarring. The skin is exposed to a blue light and destroys the bacteria that build up to form acne. The procedure doesn't really hurt, and only leaves a little temporary redness.
A oral retinoid taken on a daily basis can improve acne, but it usually takes four to six months for desirable results to be noticeable. They work by reducing the production of sebum, which is the material produced by the sebaceous gland to keep the skin moist. Overproduction can cause the pores to become clogged and pimples to develop, so oral Retinoids help to keep the production at a necessary level.
