D-Panthenol (also called dexpanthenol or provitamin B5) is a stable, skin-friendly alcohol form of pantothenic acid — a B vitamin your body needs for cellular repair and energy production. When applied to the skin, it's quickly absorbed and converted into pantothenic acid, the biologically active form that gets to work right away. It's one of the most widely used ingredients in dermatology and cosmetics precisely because it's effective, stable, and almost universally tolerated.
Once absorbed, panthenol is converted into pantothenic acid, which serves as a building block for coenzyme A — a molecule involved in fatty acid synthesis and cell membrane repair. This supports the skin's ability to rebuild its protective barrier, retain water, and reduce inflammation. Panthenol also stimulates the activity of fibroblasts, the cells responsible for producing collagen and closing wounds.
Topical concentrations typically range from 0.5% to 5% in skincare products, with 1–2% common in leave-on formulas and up to 5% in wound care and medicated creams. It appears in shampoos and conditioners (for hair moisture and scalp support), sprays for burns, gels for post-tattoo care, and ointments for diaper rash and wound healing. It's also used in eye drops for dry eye relief.
Panthenol has been used in clinical wound care since the 1940s and became a cosmetic staple by the 1980s. Bepanthen (Bayer), one of the most recognized wound-care brands globally, has used dexpanthenol as its active ingredient for decades. Its dual identity — both a pharmaceutical wound treatment and a mainstream cosmetic ingredient — is unusual and reflects its genuinely strong safety and efficacy record.
