Phytosterols

Plant analogs of cholesterol are structural components of plant cell membranes. In cosmetics, they restore the skin's lipid barrier, soothe irritation, and have an anti-aging effect. A natural alternative to animal-derived cholesterol in barrier products.

What is it?

Phytosterols are a mixture of natural plant-derived sterols: β-sitosterol (main, ~50–60%), stigmasterol (~15–25%), campesterol (~15–20%), brassicasterol, and others. They are obtained from plant oils (sunflower, soy, corn, pumpkin seeds). Molecular structure: very similar to cholesterol but with an additional carbon substituent in the side chain. Fat-soluble. They are part of plant cell membranes. In the skin: functionally similar to cholesterol — they regulate membrane fluidity and support barrier function.

Barrier and restorative creams, anti-aging products for mature skin, products for sensitive and atopic skin, post-aggressive procedure products (laser, peels).

Key Benefits

✦

Skin barrier restoration — a plant alternative to cholesterol

Cholesterol is a critical component of intercellular lipids in the stratum corneum. When the barrier is damaged (atopy, aggressive cleansing, age-related changes), cholesterol decreases. Phytosterols are structurally similar and partially compensate for this deficiency. Studies show: topical application of phytosterols accelerates barrier restoration and reduces TEWL. Plant origin makes them a vegan alternative to cholesterol (animal).

◈

Anti-inflammatory and soothing action

β-sitosterol and other phytosterols demonstrate anti-inflammatory properties: they inhibit the synthesis of pro-inflammatory cytokines (IL-1, TNF-α) and prostaglandins. Clinically confirmed: they reduce redness and irritation in atopic dermatitis and rosacea. Effective as anti-inflammatory components in soothing creams for reactive skin. The mechanism is similar to that of steroid creams, but without their side effects.

✧

Anti-aging action — support for cell membranes

With age, the level of cholesterol in the stratum corneum decreases → barrier function deteriorates → moisture loss and aging accelerate. Phytosterols replenish this deficiency, supporting the fluidity and integrity of cell membranes. Studies show improved skin elasticity and hydration with regular use of products containing phytosterols. Synergy with ceramides and fatty acids: comprehensive restoration of the lipid barrier.

Phytosterols vs Cholesterol in cosmetics

Cholesterol (animal, usually from wool — lanolin derivative): more effective for barrier restoration (identical to skin), but of animal origin. Phytosterols: plant-based/vegan, somewhat less effective in barrier restoration, but with additional anti-inflammatory action (which cholesterol does not provide). For vegan formulas: phytosterols + ceramides + fatty acids = a powerful plant barrier complex.
