A pivotal study by researchers at the University of Maryland explored methylene blue's anti-aging effects using 3D human skin models derived from middle-aged human skin cells. These models closely replicate actual human skin structure and function. Key findings include: * Improved Hydration and Thickness: Methylene blue-treated skin retained more water and increased in thickness, leading to plumper and smoother skin with reduced fine lines and wrinkles. * Enhanced Collagen and Elastin Levels: Treated skin showed higher levels of collagen and elastin, essential components for maintaining skin firmness and elasticity. Methylene blue stimulates fibroblasts, the cells responsible for collagen production, enhancing their ability to repair and regenerate the skin, thereby reducing fine lines and wrinkles
