Protective eye wear has to be worn during the treatment. A layer of cooled gel is applied to the treatment area. The hand piece of the AFT applicator is applied to this area of cooled skin and a short pulse of light of the appropriate wavelength is released.
Tanned and dark skinned people cannot be treated with AFT. Also large dark moles or lumpy pigmentation cannot be treated with AFT. Superficial sun spots and freckles respond best to AFT.
The treatment sensation may feel like the flick of an elastic band on the skin.
Sight soreness and redness like mild sunburn may be felt soon after the treatment, which disappears after a few hours. Blisters and darkening/lightening of the skin are rarely seen.
The pigmented areas treated may darken and then fade away. Some are seen to flake before disappearing either partially or completely. Between one and four treatments may be necessary 4 weeks apart.
