What is Panthenol?

Panthenol, also known as provitamin B5, is a humectant and emollient that has become a staple ingredient in Korean skincare formulations. When applied topically, panthenol converts to pantothenic acid (vitamin B5) in the skin, delivering deep hydration and supporting the skin's natural barrier function.

Key Benefits of Panthenol

Deep Hydration: Panthenol is a powerful humectant that attracts and binds water to the skin, providing long-lasting moisture. It penetrates deep into the skin layers, hydrating from within rather than just sitting on the surface.

Barrier Repair: This ingredient strengthens the skin's protective barrier by promoting lipid synthesis and improving barrier function. A healthy barrier means better moisture retention and protection against environmental stressors.

Soothing & Calming: Panthenol has anti-inflammatory properties that help calm irritated, red, or sensitive skin. It's particularly beneficial for compromised skin conditions and post-procedure recovery.

Wound Healing: Studies show panthenol accelerates skin regeneration and wound healing, making it valuable for treating minor skin damage, irritation, and inflammation.

How Panthenol Works in Skincare

Once absorbed, panthenol converts to pantothenic acid, which plays a crucial role in cellular metabolism and skin regeneration. It works by:

• Binding water molecules to increase skin hydration levels
• Stimulating fibroblast proliferation for improved healing
• Reducing transepidermal water loss (TEWL)
• Supporting the synthesis of lipids in the stratum corneum

Who Should Use Panthenol?

Panthenol is suitable for all skin types, including:

• Dry skin: Provides intense hydration and prevents moisture loss
• Sensitive skin: Gentle, non-irritating, and soothing
• Oily/Acne-prone skin: Lightweight, non-comedogenic hydration
• Mature skin: Supports barrier function and skin regeneration
• Compromised skin: Aids in healing and barrier repair

Cautions & Side Effects

Panthenol is generally very safe and well-tolerated across all skin types. Rare cases of mild irritation may occur in extremely sensitive skin. It's safe for use during pregnancy and can be combined with virtually all other skincare ingredients, including actives like retinoids, acids, and vitamin C.

How to Incorporate Panthenol into Your Routine

Look for panthenol in:

• Serums and essences (typically 2-5% concentration)
• Moisturizers and creams
• Sheet masks and sleeping masks
• Toners and mists
• Soothing and barrier repair products

Panthenol works well in both morning and evening routines and can be layered with other hydrating ingredients like hyaluronic acid, glycerin, and ceramides for enhanced benefits.

The Bottom Line

Panthenol is a versatile, evidence-based ingredient that delivers real results for hydration, barrier repair, and skin soothing. Its excellent safety profile and compatibility with all skin types make it a cornerstone ingredient in K-beauty formulations. Whether you're dealing with dryness, sensitivity, or simply want to maintain healthy, hydrated skin, panthenol is an ingredient worth incorporating into your skincare routine.
