The classic combination medium depth peels for the face and scalp include solid CO2 plus TCA 35%, JS plus TCA 35%, and GA 70% plus TCA 35%.Baker-Gordon’s formula (2.1% croton oil) was the standard phenol-croton oil peel from 1962 to 2000, but since 2000 Hetter’s formulas (less than or equal to 1.6% croton oil) have been the standard.Segmental phenol/croton oil peels limited to one or two cosmetic units, over 10–15 minutes per unit, do not require cardiac monitoring.What’s New?Medium and deep chemical peels: updated safety and patient selection information, histology, techniques, healing stages and endpoints.Chemical peels for acne scars.What’s Coming?More publications on deep chemical peels (segmental and full face) showing safety protocols, procedures, and technique.
