Skin Barrier Support

Healthy skin relies on a delicate balance of lipids, moisture and protective layers that function by working with the skin’s own composition, using plant derived ingredients that mimic its structure, and replenish what’s been lost.

Oils rich in fatty acids can be applied to nourish and soften, and humectants such as glycerin or hyaluronic acid can be used to help draw in moisture.

It is thought that consistent use of such soothing botanicals and lipid replenishing ingredients will help maintain skin that is both soothed and comfortable and can help to improve the skin’s resilience over time.

The outermost layer of the skin (called the stratum corneum) is often described as a brick and mortar system. Lipids act as the binding material that keeps skin cells held together, helping to prevent moisture loss and maintain resilience (1).

Healthy skin contains roughly 50% ceramides, 25% cholesterol and 15% fatty acids (2). Natural skincare focuses on replenishing these lipids using plant derived alternatives such as phytoceramides, squalane and essential fatty acids to help fill gaps and reinforce the barrier.

Particularly in sensitive individuals, or after an intense skin treatment like a chemical peel, a gentle routine that avoids stripping the skin helps maintain the acid mantle (that’s the skin’s protective acidic film). This way, you can reduce the feeling of skin sensitivity and support skin healing (3).

Replenishing lipids such as ceramides and fatty acids helps strengthen the skin’s structure and reduce moisture loss. In this regard, ingredients like squalane closely resemble the skin’s own sebum. So, they allow for effective hydration without clogging pores (4).

Botanical extracts including colloidal oatmeal, aloe vera and marshmallow root provide a soothing layer across the skin. They are thought to be great at helping to reduce inflammation, lock in moisture and support natural repair processes (5).

Apricot kernel oil contributes to this process by softening and smoothing the skin while delivering vitamins A, C and E (6). That’s because its lightweight texture allows it to absorb easily, supporting long lasting moisturisation and helping improve skin tone and radiance.

When the skin barrier is compromised, it can get quite uncomfortable. It may present as dryness, redness, stinging or increased sensitivity. Therefore, during this time, it is important to avoid harsh actives (active ingredients) such as retinol or strong exfoliating acids that may further weaken the barrier. You may choose to stick to a very gentle cleanser and moisturiser, and only use these products until symptoms improve (7).

Use plant derived “skin identical” ingredients such as squalane and phytoceramides

Support moisture with humectants like glycerin and hyaluronic acid

Soothe and protect with botanicals such as colloidal oatmeal, aloe vera and marshmallow root

Avoid harsh actives like retinol and strong exfoliating acids when the barrier is compromised

Maintain the acid mantle with gentle, non stripping products

Focus on consistent hydration and nourishment to restore resilience
