This form of treatment is occasionally used on small broken veins on the skin of the face and legs, but it can also treat warts that stand proud above the skin surface.
It is particularly valuable in dealing with small, protuberant skin tags.
Excision and Punch Biopsy
Certain skin condition can be treated only by complete surgical excision or removal of a piece of thick skin (including epidermis, dermis and subcutaneous fat). Only a dermatologist or plastic surgeon can decide when this technique is necessary.
Punch Biopsy can be used to treat stable patches of Vitiligo. The depigmented skin is removed using different punches and the normal skin is used to fill the defects.
