The Potential Uses of N-acetylcysteine in Dermatology: A Review.

Background

In recent studies, N-acetylcysteine has been shown to be efficacious in several dermatologic conditions.

Objective

The aim was to review clinical trials that assess the efficacy of N-acetylcysteine in cutaneous disorders.

Design

The PubMed database was searched and a manual search of clinical trials in the references was performed. Studies included randomized, controlled studies, uncontrolled studies, meta-analyses, and systemic reviews published between years 1966 and 2017.

Results

Efficacy of N-acetylcysteine was shown in excoriation disorder, onychophagia disorder, trichotillomania, acne vulgaris, Type I lamellar ichthyosis, bullous morphea, systemic sclerosis, toxic epidermal necrolysis, atopic dermatitis, xeroderma pigmentosum, and pseudoporphyria. Studies also show benefits in wound healing and photoprotection.

Conclusion

The review of available literature suggests that N-acetylcysteine could potentially serve as a safe, tolerable, and effective therapeutic option for a variety of dermatologic conditions.
