Panthenol, also known as provitamin B5, is a highly effective skincare ingredient renowned for its moisturising, soothing, and skin-repairing properties. Once absorbed into the skin, it is converted into vitamin B5, where it helps attract and retain moisture while supporting the skin's natural barrier. Panthenol is particularly beneficial for dry, sensitive, or irritated skin, as it helps reduce redness, calm inflammation, and improve overall skin softness. Its ability to strengthen the skin barrier also helps protect against moisture loss and environmental stressors.
In K-Beauty, panthenol is commonly found in toners, essences, serums, moisturisers, and barrier repair creams that focus on maintaining healthy, resilient skin. Korean skincare values panthenol for its ability to provide long-lasting hydration while soothing stressed or compromised skin without feeling heavy. It is often paired with ingredients such as hyaluronic acid, centella asiatica, ceramides and niacinamide to enhance hydration, reinforce the skin barrier, and support skin recovery. With regular use, panthenol-infused products can help leave the skin feeling smoother, calmer, and better protected against daily environmental damage.
