In addition to anti-diabetic activity, berberine has hydrating properties used for their anti-wrinkle, skin-lightening and anti-inflammatory activity. This function has made berberine an ingredient included in many cosmeceutical products. Berberine may be useful for vitiligo and malignant melanoma based on preliminary studies highlighting its effect on melanin synthesis in animal models. Berberine can increase glucagon-like peptide-1 (GLP-1) insulin secretion in the intestine. Insulin is a hormone that helps regulate blood glucose levels by signaling cells to absorb glucose from blood. Elevated insulin can promote androgen synthesis, resulting in excess sebum production, a known correlates of acne severity.
Berberine is a derivative of the plant Berberis vulgaris, a shrub with purported medicinal properties. Berberine is an isoquinoline alkaloid with anti-inflammatory, antioxidant, antibacterial and antimicrobial properties.
Berberine is considered safe for short-term application on the skin for all skin types and tones based on available evidence.
The available evidence does not suggest any contraindications for berberine, but individuals with an adverse reaction to it should avoid products containing berberine.
