Trans epidermal Water Loss – What is it and How to Stop It

If you are struggling with dehydrated or dry skin, one of the causes may be trans epidermal water loss (TEWL). You're losing water and moisture from your skin. TEWL can lead to a variety of dry skin conditions — including severe dehydration — but there are ways that you can keep your skin hydrated or prevent dryness from occurring in the first place. What Is Trans epidermal Water Loss? To understand TEWL, let's revisit the layers of our skin. Our skin is made up of three primary layers, the outermost being the epidermis (aka what you look at in the mirror). The dermis is the middle layer, and the hypodermis is the innermost layer. TEWL occurs when water passes from the dermis through the epidermis and evaporates through the skin barrier.

How does skin change over the years?

Skin is a living organ and undergoes significant changes during a person’s lifetime: from the delicate skin of a new-born baby, through the teenage years when some are acne-prone, to the wrinkles of later life. Each stage has its own demands and skin care should reflect these changing needs. Choosing appropriate products to cleanse, protect, nourish and repair skin at each of these stages will help to keep it healthy and ensure that your skin looks and feels its natural best, whatever your age. How is skin different at each age and stage?

Pigmentation

Hyperpigmentation is defined as darkening patches of skin. This occurs when the skin produces more melanin, the pigment that gives skin its colour. Sun damage is the main cause of pigmentation. The initial melanin production from sun exposure acts as a natural sun screen to protect from harmful rays. However excess UVA/UVB exposure disrupts the melanin production, which leads to increased pigmentation.
