How It Works
Skin dehydration and dryness can be caused by many different things: ageing, cold weather, travelling, hormonal changes, air conditioning, central heating: the list goes on. These changes can result in an increase of TEWL (transepidermal water loss), a process in which water rises to the skin surface and escapes, resulting in low moisture levels within the skin. H.E.O. Mask is designed to tackle the visible signs of dryness and dehydration, whilst supporting the natural skin barrier for improved long-term moisturisation.
1. Humectants act as moisture magnets, drawing water in to rehydrate, smooth and plump the skin. H.E.O. Mask features humectant heroes multi-weight hyaluronic acid, glycerin and Natural Moisturising Factors (NMF) that replenish the skin with lost water by creating a reservoir of hydration in the upper layers of the skin.
2. Glyceryl glucoside helps to stimulate moisture channels to increase water flow throughout the layers of the skin, while blue sea kale supports the natural production of hyaluronic acid in the skin, to help recharge the skin's hydration levels long term.
3. Emollients squalane, ceramides and linoleic acid (vitamin F) use their skin-identical, oil-loving properties to effortlessly slip into the natural skin barrier, to fill any gaps where moisture can escape whilst deeply nourishing the skin.
4. Occlusive dimethicone is made up of larger molecules than the other key ingredients, which means it works to form a breathable barrier over the skin surface to lock in the benefits of the humectants and emollients, while physically preventing TEWL.
How To Use
1. After cleansing, apply as the last step of your evening skincare routine.
2. Smooth an almond-sized amount of Step 1 of H.E.O. Mask over face, neck and décolletage, avoiding the eye area.
3. Allow to absorb for a few minutes then gently massage another almond-sized amount of Step 2 of H.E.O. Mask into the same areas. Leave on overnight.
4. Apply 2-3 times a week or as required.
5. Patch testing prior to use is advised. Refer to medik8.co/patch for an in-depth guide to patch testing.
Ingredients
Multi-Weight Hyaluronic Acid
With a unique ability to attract and retain more than 1,000x its own weight in water, hyaluronic acid draws moisture from the surrounding atmosphere into the skin, leaving the complexion both nourished and supple.

Natural Moisturising Factors
Found naturally in the upper layers of the skin, Natural Moisturising Factors (NMF) work to attract and retain water. NMF levels in the skin decline as we age, therefore NMF components, including urea, amino acids and sodium PCA work to restore hydration within the complexion.

Ceramides
Naturally found in the skin barrier, ceramides help to replenish the skin, working to mimic the natural lipid barrier to intensely restore and nourish.

Squalane
An almost skin-identical lipid, squalane helps to restore the skin’s natural moisture barrier and deeply moisturises the complexion.

Dimethicone
Made up of large molecules, dimethicone forms a breathable barrier over the skin’s surface which helps to lock in hydration and nourishment for prolonged results.

The Science Behind

Skin dryness is one of the most common skin concerns. It is made worse by seasonal weather changes and modern lifestyles. Not only is dry skin uncomfortable, it's a visible problem, causing flakiness, fine lines and peeling makeup. Add to that a weakened skin barrier making you more sensitive, itchy and vulnerable to the environment - this is definitely something that’s important to address. Unfortunately, it’s not that easy and many usual day and night creams just don’t have the power to maintain skin moisture for a drier skin type or skin exposed to a dry environment.

To solve the problem the Medik8 research team took a step back and asked some fundamental questions on how to moisturise the skin. It soon became clear it came down to three approaches with three different types of ingredients: increasing water content (humectants), preventing the rise of water to the upper skin surface (emollients), and minimising evaporation (occlusives).

H.E.O. Mask contains all three fundamentals, in an optimised ratio for synergistic hydration power.
