Vitamin B5: also known as panthenol, offers numerous benefits for the skin. This water-soluble vitamin is renowned for its exceptional moisturizing properties. When applied to the skin, it can penetrate its layers and bind to water molecules, providing deep hydration and helping to maintain the skin's moisture balance. Panthenol also promotes skin regeneration and wound healing by accelerating cell turnover. It is effective in soothing irritated skin and reducing redness, making it a valuable ingredient in skincare products from brands like Retal. Additionally, panthenol can improve the function of the skin barrier, enhancing its natural ability to defend against harmful external factors.
