All skin types, tones and ages, especially sensitized, sensitive and stressed. Ideal post treatment, menopausal or young skin.

Skin barrier importance

The skin’s barrier comprises of numbers ‘parts’, each of which need to remain intact and healthy. These include the Natural Moisturising Factor (NMF), the Microbiome and the Acid Mantel.

NATURAL MOISTURISING FACTOR
is an expansive group of chemicals and substances including amino acids, lactates, sugars, salts, PCA, urea and peptides that work together to keep the skin’s surface intact, supple and hydrated. As we age, the NMF naturally weakens, and external, environmental factors, such as harsh exfoliation and pollutants, can damage and alter it, leading to dryness, accelerated ageing, sensitivity, skin damage and the ability of pathogens to enter the skin and moisture to escape.

THE ACID MANTLE (also called the hydro-lipid film)
is a fine layer on the outer surface of our epidermis that is made of a mixture of dead skin cells, oils (sebum), amino acids and other skin secretions and sweat* – it is the fine protective layer that sits between us and the world. This helps keep one’s skin at an optimal, slightly acidic pH between 4.5- 6.2 which is a protective barrier and the body’s first defence against viruses, bacteria and other pathogens. It is also our main protector against Trans Epidermal Water Loss (TEWL) which simply means water or hydration escaping from the deeper layers of the skin, in other words, dehydration.
*Acid Mantle composition – water (from sweat), lactic acid, urocanic acid, fatty acids, pyrrolidine carboxylic acid, eccrine glands which secrete amino acids.

SKIN MICROBIOME
Is the ecosystem of millions of micro-organisms that live on the surface of our skin that includes bacteria, viruses and fungi. It is our body’s first line of defence and a vital part of our immune system.
