(HealthDay News) — Botanical extracts may be helpful in the treatment of hyperpigmentation, although identification of hyperpigmentation subtype may be important for treatment prognosis, according to a review published in the February issue of the Journal of the American Academy of Dermatology.

Whitney A. Fisk, from the University of California at Davis, and colleagues conducted a systematic literature review to assess clinical evidence for the use of botanical agents in the treatment of hyperpigmentation.

The researchers found that, of the 26 articles meeting inclusion criteria, several showed botanical agents as promising treatment options, but few studies were methodologically rigorous. For epidermal melasma and hyperpigmentation induced by ultraviolet radiation exposure, several plant extracts and phytochemicals effectively lightened signs of the conditions. However, for treatment of solar lentigines or dermal hyperpigmentation, the results were mixed.

“Botanical extracts may play an integrative role in the treatment of hyperpigmentation and further studies that integrate them with standard therapies are needed,” the authors write.
