What is Glycerin & What Does Glycerin Do for Your Skin?

Glycerol, also commonly referred to as glycerin, is a natural substance produced by the body and can also be extracted from vegetable oils. Glycerin is a transparent, colorless, fragrance-free substance that acts as a humectant and belongs to the skin’s natural moisturizing factors (NMFs). A humectant draws water into the skin’s stratum corneum (the outermost layer) from the air and also from within the skin. This property makes glycerin an excellent moisturizing agent, particularly in colder environments where skin dries more easily.


As well as attracting moisture, glycerin helps skin become healthier by retaining internal moisture content. This can leave skin smoother and softer. Glycerin also has the ability to easily diffuse into the surface layer of the skin, which allows it to easily exert its beneficial effects.


Due to these amazing properties, glycerin is in many skincare products.

What is glycerin used for?

Glycerin has multiple uses as it is a versatile ingredient that can be used in a wide range of products, especially in skincare and hair products. It can be used in body moisturizers and exfoliators for both oily and dry skin types.

What Are The Skin Benefits of Glycerin for Skin?

Moisturizing

Through its humectant properties, glycerin is able to draw water from both the environment and the skin into the stratum corneum. This helps retain moisture in this layer of skin that is most vulnerable to drying. Glycerin is easily absorbed into the skin, which also aids its effectiveness as a moisturizing agent.


Helps strengthen the skin barrier

One of the most important functions of the skin is to act as a protective barrier. This barrier function of the skin helps prevent moisture loss from the skin into the air. It also protects the skin from environmental stressors, pollutants, and irritants. Studies have shown that glycerin can boost the skin’s barrier function. Since glycerin boosts this essential function, it can also help prevent the skin from drying.


Makes skin exfoliation easier

Through glycerin’s moisturizing effect, it helps the outermost skin layer stay hydrated, which makes it easier to exfoliate – this can ultimately lead to skin feeling smooth and soft.

What Skin Types Can Use Glycerin?

Glycerin has a gentle effect on the skin, and this makes it suitable for a wide range of skin types. It is such a versatile ingredient that can be used in multiple product types.


Dry skin

Glycerin can benefit dry skin due to its humectant properties: the ability to draw in moisture from within the skin layers and from the air. It also helps the skin barrier keep moisture locked within the skin. In particular, if glycerin combines with occlusives such as dimethicone, this can tackle skin dryness synergistically.

Oily skin

Glycerin has a non-greasy texture, which makes it suitable for those with oily skin types. It is also non-comedogenic which means it does not clog the pores.


Combination skin

As glycerin is suitable for both dry and oily skin types, it can benefit combination skin as well.

Glycerin & Skin Sensitivity

If you have sensitive skin, this can occur from damage to the skin barrier function or because you naturally have a thinner skin barrier. This makes the skin more vulnerable to irritants, as they can penetrate the skin more easily. A thin or damaged skin barrier can also allow moisture to be lost from the skin more easily. 


Since glycerin can help to boost the skin barrier, this ingredient can help sensitive skin. The humectant nature of glycerin also means it draws moisture in from the air and deeper skin, this can help tackle dryness in sensitive skin.
