Skincare Spotlight: Glycerin

While the benefits of hyaluronic acid in skincare are well known, there’s an equally effective hydrator that also should be on your radar – glycerin. A colourless liquid naturally occurring in the skin, glycerin (or glycerol) is predominantly prized in skincare for its moisturising properties.

Derived from plant or synthetic sources, cosmetic glycerin may hold the key to restoring your skin to glowing good health, while alleviating the discomfort of dry skin conditions. Here’s everything you need to know about this marvellous moisturiser

Glycerin Attracts Moisture

Glycerin’s hydrating properties make it a gold-star ingredient for combating dryness. First and foremost, glycerin acts as a powerful humectant. This means it’s able to attract and bind moisture from the air into the skin’s upper layer for increased hydration. As an added bonus, this also enhances the absorption of other ingredients into the skin.

And Retains It

The benefits don’t end with short-term moisture gains, as glycerin is also an emollient. Emollients work by creating a protective film on the skin to lock in moisture, leaving the skin soft and supple. Particularly beneficial for dry and sensitive skin, emollients help to alleviate itching and discomfort, and prevent cracks in atopic skin.

However, it’s not only dry skins that can benefit from added hydration. Glycerin promotes a healthy healing environment in acne-prone skin, and can counteract the drying effects of active ingredients such as beta hydroxy acids.

Glycerin in La Roche-Posay Skincare

Glycerin’s hydrating properties make it an effective ingredient for a diverse range of face, body and cosmetic products. La Roche-Posay products use naturally derived plant based Glycerin.


Enriched with glycerin to nourish dry, sensitive and reactive skin, Toleriane Dermo Cleanser is a high-tolerance, minimalist facial milk that gently cleanses the skin while preserving its moisture barrier. Free from fragrances and preservatives, it thoroughly removes dirt, oil and impurities without causing irritation.


Glycerin is a key ingredient in the Toleriane range of facial moisturisers for sensitive skin – all of which are non-comedogenic and free from common irritants including fragrance and preservatives.

For dry and sensitive, reactive or allergic skins, Toleriane Ultra is an ultra-pure formula that combines hydrating glycerin with Neurosensine™ and La Roche-Posay thermal spring water for intensive soothing. Meanwhile, Toleriane Sensitive helps to relieve the tight, burning and pulling sensations often experienced by normal to combination intolerant skin types. Dry and intolerant skins are best suited to Toleriane Sensitive Riche – a creamy formula combining glycerin with lipid-replenishing shea butter.

Acne Management

It is important to keep acne-prone skin hydrated, as products that ‘dry out’ the skin will only cause it to compensate by producing more oil. Ideal for cleansing oily skin with acne, Effaclar Micellar Water Ultra gently removes all traces of makeup, dirt, excess sebum and impurities, without stripping the skin of moisture. Free from potentially irritating soap, colourants and alcohol, it is formulated with hydrating glycerin as well as purifying zinc.  

Effaclar Duo (+) helps to soothe acne, unclog pores and reduce breakouts by addressing the root causes of acne. With LHA and salicylic acid for gentle microexfoliation, soothing niacinamide, and procerad™ to minimise post-inflammatory pigmentation, Effaclar Duo (+) is also enriched with glycerin to ensure the skin stays hydrated and irritation-free.

Anti-Itching for Dry, Atopic Skin

By increasing the skin’s moisture levels, glycerin can also help break the vicious cycle of itching and aid in the repair of extremely dry, atopic skin. Enriched with lipid-replenishing shea butter and niacinamide in addition to glycerin, Lipikar Baume AP+ is a minimalist body balm that provides relief even for newborns through to adults. Providing 24-hour anti-scratching efficacy, it directly targets the triggers of inflammation to reduce tightness and discomfort.
