Methylene blue is a synthetic dye with a rich history in medicine, but it’s recently gained attention in the skincare world due to its potential antioxidant and anti-inflammatory properties. Often found in products aimed at targeting skin aging, it helps protect against oxidative stress and can improve the skin’s barrier function. It has been incorporated into some serums and creams, primarily for its ability to promote healing and rejuvenation. Additionally, methylene blue’s antibacterial effects may make it useful in treating acne and other inflammatory skin conditions. However, while it’s gaining traction, more research is needed to fully understand its long-term effects and safety in cosmetic formulations.
