These after acne “war signs “ can be divided into 2 types:
The flat pink reddish spots that are caused by enlargement of microscopic capillaries, These will usually fade by themselves even without treatment in a few weeks to months.
Flat brown spots: Some of them will fade by them selves and some will need further treatment. Treatment for these spots is usually quite easy and will include whitening creams prescribed to you by your Dermatologist or superficial chemical peels.
The more persistent pink and brown spots can be also treated with light sources, called Intense Pulse light (IPL). These IPL’s produce intense pulses of light very similar to camera flash. The light is absorbed in small capillaries and the melanin globules in the spots causing them to fade.
