Pantothenic Acid is vitamin B5, a water-soluble vitamin used in skincare formulas, often as its more stable derivative panthenol. In topical products it functions as a humectant and skin-conditioning agent, helping the skin surface feel soft and hydrated. It is a common, well-tolerated ingredient in moisturizers and after-sun or sunscreen lotions.
