Glycerin for skin hydration

Glycerin, also known as glycerol, is a sweet, colourless and odourless liquid commonly used in skincare, soap and pharmaceutical products.

It can dissolve easily and hold onto moisture, which makes it very effective in formulas designed to hydrate and protect the skin (1).

Why glycerin is used in skincare

Glycerin is best known as a humectant, meaning it attracts moisture.

This quality makes it particularly useful for dry, flaky or uncomfortable skin, including skin affected by drying acne treatments and retinol product usage.

It is also hygroscopic, meaning it absorbs water from the surrounding environment and supports long-lasting hydration (2).

Key benefits

Skin dryness: Glycerin works as a hydrating agent by drawing moisture into the skin and helping prevent dryness, whilst helping to soften rough areas and smooth texture.

Scarring and fine lines: It also supports skin renewal, which may help reduce the appearance of marks left behind by blemishes over time.

Adaptable to many skin types: Because it is gentle and well tolerated, glycerin suits all skin types, including sensitive, acne-prone and mature skin (3).

How it works

Glycerin works by attracting water from the air and helping draw moisture towards the skin’s outer layer. This keeps the surface of the skin comfortably hydrated, improving softness, suppleness and overall appearance (4).

Skin compatibility

Glycerin is widely used in skincare and is generally considered gentle enough for regular use. It is commonly found in products formulated for sensitive or damaged skin and is known for being non-comedogenic (5).

How to use it

Glycerin is commonly found in many everyday products such as moisturisers, cleansers, serums and toners.

It’s usually combined with other ingredients that also help seal in moisture, allowing the hydration it attracts to remain in the skin for longer. It also makes a useful addition in products such as make-up setting mists.
