Darker skin types complications

In contrast to photodamage, when treating conditions such as melasma and PIH, retinoids should either be discontinued 1 or 2 weeks before peeling or completely eliminated from the peeling preparation to avoid postpeel complications such as excessive erythema, desquamation, and PIH. These conditions are more common in darker racial/ethnic groups, populations at greater risk for postpeel complications. Similar precautions should be taken in acne patients with darker skin types (V and VI).
