Highest-evidence picks

Glycerin

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.

Colloidal Oatmeal

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.

Urea

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.

Niacinamide

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

Panthenol (Provitamin B5)

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

Ceramide NG

A bioidentical ceramide from the non-hydroxylated class. One of the main lipids of the stratum corneum – restores the barrier and lowers TEWL. Pregnancy-safe.

What to know

The skin barrier is the stratum corneum plus the intercellular lipids between corneocytes: ceramides (50%), cholesterol (25%), free fatty acids (25%). When this balance is disrupted – by aggressive cleansing, frequent peels, atopic dermatitis, xerosis, or post-laser recovery – skin loses water, reacts with stinging and redness, and becomes «sensitive» to routine cosmetics.

Barrier repair works through three mechanisms. First, external lipid replacement: ceramides NP, AP, EOP + cholesterol + fatty acids in a 3:1:1 ratio. Such formulas produce clinical improvement in atopic dermatitis within 2–4 weeks. Examples include CeraVe Healing Ointment, Avene Cicalfate+, La Roche-Posay Lipikar.

The second mechanism is stimulation of endogenous lipid synthesis. Niacinamide at 4–5% increases ceramide production in situ. Panthenol (provitamin B5) drives keratinocyte differentiation and accelerates fibroblast migration. Madecassoside from Centella asiatica accelerates regeneration and reduces inflammation.

The third is occlusion: stop water loss and give the barrier time to recover. Petrolatum reduces TEWL by 99% and is considered the dermatology gold standard. Squalane, dimethicone, and mineral oil are lighter occlusives that suit oily and combination skin.

Colloidal oatmeal (Avena Sativa Kernel Flour) is the only OTC ingredient FDA-approved as a skin protectant. It works in atopic dermatitis and sensitised skin, calming itch and redness. Common in post-procedure formulas.

When the barrier is compromised, pull all actives from the routine: retinoids, AHA/BHA, high-strength vitamin C, essential oils, fragrance. Actives can return 2–3 weeks after skin stops reacting to a plain moisturiser.

Frequently asked

How many barrier repair ingredients are in the Evigrade database?

Evigrade currently tracks 152 ingredients in the «barrier repair» category. Of those, 117 carry evidence tier A or B.

Which barrier repair ingredients are safe during pregnancy?

136 ingredients in this category are flagged as safe during pregnancy at typical cosmetic concentrations. Always confirm the choice with an OB-GYN.

Which ingredients suit sensitive skin?

146 ingredients in this category show both low irritation potential and low allergen risk, making them safe even for reactive and sensitised skin. A patch test is still advisable before first use.

How should I start using ingredients from this category?

Start with a single high-evidence ingredient (tier A or B) at a low concentration, 2–3 times per week. After 2–3 weeks without reaction, frequency can be increased. Do not introduce two new actives at once – if skin reacts, you won't know which one caused it.
