Panthenol, or vitamin B5, is known for its moisturizing and repairing properties. This provitamin is essential for the intermediate metabolism of the human body, and its deficiency can lead to various dermatological disorders. DL-panthenol is used in a wide range of cosmetic products due to its benefits for the skin, hair, and nails. On the skin, it acts as a conditioning agent, providing deep hydration and stimulating epithelialization to aid in healing and offer anti-inflammatory effects.
