Glycerin, also known as glycerol, is a versatile and widely used humectant in skincare formulations. This colorless, odorless, viscous liquid is derived from both natural and synthetic sources, including vegetable oils and petrochemicals. As a hygroscopic substance, glycerin attracts and retains moisture, making it highly effective in hydrating and moisturizing the skin.

In skincare products, glycerin typically comprises 0.5% to 5% of the formulation. It functions by drawing water from the environment and deeper skin layers to the surface, enhancing skin hydration and improving barrier function. This moisture-binding property helps to reduce transepidermal water loss, leading to smoother, more supple skin.

Glycerin's low molecular weight allows it to penetrate the stratum corneum, providing hydration to deeper skin layers. It also exhibits emollient properties, helping to soften and smooth the skin's surface. Additionally, glycerin has been shown to enhance the penetration of other active ingredients in skincare formulations.

While generally well-tolerated, high concentrations of glycerin can potentially cause a tacky feel on the skin or draw out too much moisture in low-humidity environments. Therefore, it is often combined with other moisturizing agents for optimal efficacy and skin feel.

Panthenol, also known as pro-vitamin B5, is a versatile and widely used ingredient in skincare and cosmetic formulations. This alcohol form of pantothenic acid readily converts to vitamin B5 when absorbed by the skin, offering numerous benefits for skin health and appearance.

As a humectant, panthenol attracts and retains moisture, helping to hydrate the skin and improve its barrier function. This property makes it particularly effective in treating dry, flaky, or irritated skin conditions. Panthenol also exhibits anti-inflammatory properties, soothing redness and promoting skin healing.

In hair care products, panthenol can penetrate the hair shaft, improving moisture retention and enhancing shine and manageability. Its ability to form a protective film on the skin and hair makes it valuable in leave-on and rinse-off formulations alike.

Panthenol is generally well-tolerated by most skin types and is often used in concentrations ranging from 0.5% to 5%. Its stability in various pH environments and compatibility with other common skincare ingredients make it a versatile choice for formulators. Regular use of panthenol-containing products can contribute to improved skin texture, reduced signs of irritation, and enhanced overall skin health.
