Severe hyperpigmentation and scarring following glycolic acid peel treatment in combination with low-dose isotretinoin

摘要

BackgroundThe application of systemic isotretinoin in the treatment of cutaneous photoaging has been well investigated. In addition, well-recognized topical antiaging therapies such as superficial chemical peeling (CP) with α-hydroxy acids have been shown to be more helpful when combined with low-dose oral isotretinoin. Even though the combination of systemic isotretinoin and medium to deep CP has been associated with serious side effects such as delayed wound healing and enlarged incidence of scarring, to date superficial CP and concomitant systemic isotretinoin have been considered safe.Case presentationIn this report, we present the case of a patient receiving low-dose oral isotretinoin therapy who developed severe painful erythema and erosions that led to permanent hyperpigmentation and scarring of her face and neck after undergoing superficial CP with glycolic acid.ConclusionsThere is a potential risk of hyperpigmentation and scarring with the use of a combination of low-dose oral isotretinoin and glycolic acid peeling.
