As we age, we can get fine pigmented blemishes and fine lines both around the eyelids and areas such as the décolleté, shoulders and neck.
A Trichloroacetic acid chemical peel (TCA peel) is a medium depth peel that does cause noticeable redness and exfoliation. We use TCA peel in different concentrations to be either a superficial (20 –30%) or medium depth peel (30 –50%). The exact percentage we use depends on the patient’s age, the amount of skin rejuvenation required and their skin colour or Fitzpatrick skin number. We most commonly use TCA 35% concentration.
Phenol based peels are the deepest. In strong concentrations, phenol preparations are potentially cardio and renal toxic and so we rarely use them.
A Trichloroacetic acid chemical peel helps reverse solar lentigines, actinic keratosis and improving skin texture but has only a marginal effect on fine wrinkles. It tightens the skin. It helps correct epidermal atrophy and atypia and helps lay down new sub-epidermal collagen.
