DL-Panthenol (Vitamin B5)
Panthenol, or Pro-Vitamin B5, is present in all living cells and is a versatile ingredient in skin care because of its ability to improve skin barrier function and promote the production of collagen. It is a non-irritating vitamin and usually plant-based. It has numerous benefits for the skin. Topically applied Panthenol penetrates deep into the skin and is absorbed by the cells and turned into pantothenic acid (Pro-Vitamin B5). Once this happens, the ingredient begins to add essential moisture and create a plumping effect that makes skin look younger and smoother. Panthenol infuses moisture into the deeper layers of the skin, enabling it to diminish the appearance of wrinkles and fine lines. Research indicates that Panthenol could contribute to acne treatment because of its antibacterial components. The ingredient is completely safe for application to all skin types including acne-prone. One double blind research study surmised that consistent application of a facial moisturizer containing Niacinamide, Panthenol, and Tocopheryl Acetate improved skin tone and texture and was well tolerated among Indian women with aging facial skin. Another study concluded that the addition of 1% Panthenol to a formulation helped moisturize and maintain the integrity of skin.
