A healthy, hydrated skin with internal moisture control doesn’t need moisturisers, but for those who suffer from dry or oily skin, it is vitally important to address the rate at which water escapes from our skin, otherwise known as Trans-Epidermal Water Loss or TEWL.
Water loss is normal, but can be excessive in people with skin conditions such as eczema, psoriasis, and ichthyosis. Losing the ability to control moisture levels in the skin is often an underpinning cause for a myriad of other skin conditions, including acne and rosacea, as well as contributing to the signs of skin ageing by leaving the skin dull and lifeless. That’s why skin hydration and water control management are vital to maintaining a healthy skin environment, and should play an integral role in every skin treatment protocol.
Essentially, most skin troubles have more moisture control as a common denominator.
The skin is made up of two key layers, the Dermis and the Epidermis. The top layer of the skin is the Epidermis, and the top layer of the Epidermis is the Stratum Corneum. Despite being incredibly thin, the Stratum Corneum acts as the skin’s main barrier, stopping chemicals we come into contact with from getting inside the body, and controlling the rate at which moisture is able to leak out.
Skin lipid structure is critical in the moisture retaining functionality of the skin. The Stratum Corneum contains three types of lipids that have different chemical compositions and functions throughout the body; cholesterol, free fatty acids, and key nine ceramides, numbered 1 to 9, which account for 40-50% of the lipids in this outermost layer.
Ceramides are important to maintaining a healthy skin environment because they assist in controlling both cellular and skin water loss. This helps to prevent dehydration, impaired cellular function and hastened cell death. Skin that can’t increase skin lipid structure usually reacts in one of two ways; in some the skin will become dry and will crack, whereas in others, oil and skin cell production increase in an attempt to slow the rate at which moisture is leaving the skin. This results in thickened, oily skin that can lead to acne, or an exacerbation of acne symptoms – yes, believe it or not, oily skin is often a consequence of a lack of skin moisture.
Controlling TEWL is therefore vital to any skin routine that want to encourage a healthy environment; if the skin can control the rate of moisture loss, it won’t end up drying out, or over-compensating with oil and skin production. In short, it’s important to address your skin issues at the root.
The good news is that recent studies have shown that lipids can be replaced with topical preparations. Interestingly, all three lipids (ceramides, cholesterol, fatty acids) have to be replaced at a certain ratio to restore the barrier function of the skin; if the incorrect balance of lipids is applied, it actually takes longer for the skin to heal.
This is what we have created in our creams.
Hydratime® and Nutritime® contain a balanced blend of all 9 key Ceramindes, improving skin barrier functions to slow TEWL and restore a healthy environment. Unlike most moisturisers, we don’t simply smear a water-blocking layer on the surface, ignoring deficient water levels deeper in the skin. Instead we improve skin structures from within, controlling moisture in all layers of the skin, so that you can achieve the best possible results from your treatments this winter.
