Maca is believed to have antioxidant, anticancer, antimicrobial and anti-inflammatory effects on the skin. In mice, maca provides protection from ultraviolet radiation and has been shown to promote wound healing at low and high altitudes. Maca has been shown to support the endocrine system and help maintain hormone balance, which can impact hair and skin health.
Maca is a product of Lepidium meyenii, a plant native to the Peruvian Andes mountains. The plant is related to mustard plants and has been traditionally used for its purported health benefits, which are presumed to be due to the plant’s ability to survive the harsh climate in the mountains.
Maca is likely safe for all skin types and tones. Studies report that the local individuals recommend boiling the product prior to consumption to prevent adverse effects.
Available evidence does not suggest any contraindications for the use of products containing maca for the skin. Much of the evidence has been based on consumption or testing in mice, so individuals with a reaction to maca should avoid products containing it.
