The new Genetico-Racial Skin Classification: How to maximize the safety of any peel or laser treatment on any Asian, Caucasian or Black patient.

The popular skin classifications, notably the 'Fitzpatrick' and 'Obaji' classifications, are primarily based on skin colour. Other criteria are occasionally considered, such as the degree of skin oiliness, thickness, sensibility, etc. Although these classifications are easy to understand and apply, their simplicity limits their precision, sophistication and applicability.The new genetico-racial skin classification proposed herein suggests that skin response to any peel or laser treatment is genetically programmed and is, therefore, linked to the genetic and racial origin of the patient. In other words, in addition to skin colour, the patient's facial features and ancestry should be taken into account when classifying any skin.The new genetico-racial skin classification enables the physician to determine with great precision, and before any peel or laser treatment, the level of the patient's suitability and the expected postoperative outcomes; therefore, reducing the likelihood of complications.
