Phytosterols are plant-derived lipids capable of strengthening the skin barrier, or stratum corneum. The skin is thus protected from dehydration, soothed and made more supple. Its regeneration is promoted, whilst redness and irritation are reduced.

Skin Tolerance

A Note from Adeline Nalin, Head Pharmacist and Toxicologist at Aroma-Zone

“Phytosterols have a chemical structure similar to the skin’s natural lipids, which helps them integrate well into the hydrolipidic film. They are therefore very well tolerated by the skin and suitable for all skin types.”

A Safe Ingredient for your Health

A Note from Our Aroma-Zone Toxicologist

“The use of phytosterols is considered safe for health. However, people who are allergic to plant sterols or to the botanical species from which they are derived should exercise caution when using them.”

A Note from the Dermatologist

“Phytosterols strengthen the skin barrier, help retain moisture and soothe redness or feelings of discomfort. They are particularly recommended if you have irritated, dry or dehydrated skin, or if your skin feels tight. 

Often combined with other lipids such as ceramides, they help to protect the skin and make it more supple. Be careful, however, if you have oily or blemish-prone skin, as oily textures can cause or worsen acne.”

Dr Dima Haidar – Dermatologist

Formulation Focus with the Aroma-Zone R&D Laboratory

In cosmetic formulations, phytosterols are fat-soluble active ingredients that are incorporated into the oil phase. Derived from pine, they have a high affinity for skin lipids and act as cholesterol analogues naturally present in the stratum corneum lipid cement. By mimicking the cholesterol in the lipid cement (alongside ceramides and fatty acids, which also make up this lipid cement), they help to strengthen the cohesion of the skin barrier. The skin can therefore better withstand external aggressors, with reduced discomfort, dryness, and irritation.

For Which Skin Types?

Dehydrated skin, dry skin, sensitive skin.

Which Concerns Does This Address?
