Skin changes
Skin changes such as knots on the face and skin flaps on the neck and armpits can be effectively treated with laser. Usually a treatment session is sufficient.
After the skin change is cleared away, the underlying skin will be slightly rosy for a few months. Then the skin fades as it goes. It may take a few months up to two years for the skin to regain its normal pigmentation.
Avoid direct strong sun in the area as long as it is pink. Cover with colored pins, sun protection factor or patches if you are going to sunbathe.
