Skin barrier repair ingredients

Triterpenic saponin from Centella asiatica. Stimulates type I collagen synthesis and accelerates healing. Part of TECA (Titrated Extract of Centella Asiatica) used in scar gels.

Naturally derived uric acid derivative. Accelerates cell proliferation, reduces irritation, and softens the stratum corneum.

Prebiotic oligosaccharide that supports the skin microbiome balance. Boosts beneficial flora growth and suppresses pathogens.

Branched polysaccharide from larch with prebiotic action. Feeds beneficial skin microbiota, forms a soft protective film and reinforces the barrier.

Oil from argania fruit kernels. Contains oleic and linoleic acids, tocopherols, and sterols. Moisturizes, softens, and supports the lipid barrier.

Polysaccharide from yeast, fungal, or oat cell walls. An immunomodulator and humectant that stimulates macrophages and accelerates wound healing.

Plant phytosterol structurally close to cholesterol. Softens skin and supports the lipid barrier, especially in dryness and flaking.

Polysaccharide from sorbitol fermentation by Sphingomonas elodea. Forms a thin smooth film on skin, boosts surface smoothness, holds moisture and acts as a mild prebiotic.

Occlusive emollient made of purified hydrocarbons. Reduces transepidermal water loss by nearly 99% and restores the skin barrier after damage.

Phospholipid from soy or sunflower raw materials, hydrogenated for greater stability. Works as an emulsifier and integrates into the skin lipid barrier.

The simplest trihydric alcohol and one of the most common humectants in cosmetics. Draws water from the environment and retains it in the stratum corneum.

Finely ground oat flour with anti-inflammatory, moisturizing, and barrier properties. FDA-approved as an OTC skin protectant. Avenanthramides are the active anti-inflammatory compounds.

Lactobacillus probiotic lysate with soothing and barrier-supporting action. Appears in sensitive-skin lines such as La Roche-Posay Toleriane.

Bifidobacteria probiotic lysate, the key active in Estee Lauder Advanced Night Repair serum. Works on skin barrier recovery.

The primary triterpenic glycoside from Centella asiatica. Suppresses inflammation and stimulates type I collagen synthesis. More standardized than raw centella extract.

Fatty oil rich in oleic acid and unsaponifiable lipids. Softens dry skin and supports the lipid barrier.

Liquid wax compositionally similar to human sebum. Absorbs quickly without leaving a greasy sheen. Suitable even for oily skin.

Rich orange oil with carotenoids, vitamin E and omega-7. Restores dry skin and at higher doses can tint skin and fabrics.

Oil with an optimal omega-6/omega-3 ratio (3:1). Contains no THC. Absorbs well, does not clog pores, and strengthens the lipid barrier.

Plant butter from shea tree nuts. Rich in fatty acids and unsaponifiables with anti-inflammatory properties. Intensely softens skin and restores the barrier.

A natural moisturizing factor (NMF) present in the stratum corneum. Low concentrations moisturize; high concentrations act as a keratolytic. The gold standard for hyperkeratosis and xerosis.

Vitamin B3 form with a wide action spectrum: brightens pigmentation, strengthens the barrier, minimizes pores, and reduces sebum production.

Alcohol analogue of pantothenic acid. Penetrates skin and converts to pantothenic acid, required for coenzyme A synthesis. Accelerates healing and reduces irritation.

Plant oil high in linoleic acid. Restores the lipid barrier in xerosis. Recommended as a base oil for newborns instead of olive oil.

Lipophilic salicylic acid derivative linked to phytosphingosine (a ceramide precursor). Combines exfoliating and barrier-restoring properties.

Hydrogenated form of squalene, a natural component of sebum. A lightweight emollient that does not clog pores and restores the lipid barrier.

Sphingolipid and precursor of ceramides. Supports barrier function and regulates the skin microbiome through mild antimicrobial activity.

One of the three key stratum corneum lipids alongside ceramides and fatty acids. Helps restore the barrier in dryness and atopic dermatitis.

Tropical plant whose extract contains asiaticoside, madecassoside, and brahmoside. Stimulates collagen synthesis and reduces inflammation.

Lipids constituting approximately 50% of the stratum corneum. Ceramide deficiency is a key factor in the pathogenesis of atopic dermatitis and xerosis.
