Why A Healthy Skin Barrier Is Important? 

Your skin barrier or the Natural Moisture Factor Barrier (NMF) is a defense layer or shield against outside irritants, such as environment pollutants, UV damage,  infection and toxic chemicals. Skin Barrier When your skin barrier is working correctly and balanced, it has the ability to maintain good hydration, elasticity and  antimicrobial defense.

When the skin's barrier system is disturbed, a dysfunctional barrier can lead to breakouts, it leads to (dehydration) transepidermal water loss (TEWL), sensitivity.

What is a Natural Moisture Factor Barrier?  

The outermost layer of the epidermis, the stratum corneum.  Has two function:

  1. Physical Barrier -  A defense layer  Prevent invading allergens and bacteria .  A shield against outside irritants, such  as environment pollutants, UV damage, infection and toxic
  2. Chemical Barrier -  Prevent evaporation of water, know as Trans Epidermal Water Loss.  It's very fragile. Easy to be disrupted

What Is Transepidermal Water Loss (TEWL)?

Transepidermal Water Loss (TEWL), is the passive flow of water from the hydrated layers of the dermis and epidermis toward upper layers with a decrease water content and evaporates of moisture from the skin’s surface.

Sensitive Skin

Having a strong surface layer is important to reducing skin sensitivity.  A thin, weak or damaged skin barrier allows irritates to penetrate easily.  

Dry Skin

 A skin healthy skin barrier controls epidermal water content and the degree of water loss moisture. Skin permeability barrier function is a self-regulatory system, predetermined to stay hydrated.   

According to a  study conducted on dermatitis,  skin dryness is often associated to an inferior barrier function and an antimicrobial function of skin. Several skin diseases shows evidents of a disturbed skin barrier function, such as psoriasis and atopic dermatitis 

Plant oil application acts as a protective barrier to the skin by an occlusive effect, allowing the skin to retain moisture.

Almond, jojoba, soybean, and avocado oils, when applied topically, mostly remain at the surface of skin, without deep penetration into the first upper layers of the skin.

FFAs such as oleic acid

Free fatty acids, specifically monounsaturated FFAs such as oleic acid act as permeability enhancers
