Medik8 H.E.O Mask


Optimal Ratio Moisturisation Two-Step Overnight Mask

2 x 50ml

H.E.O. Mask is clinically proven to seal in hydration for up to 72 hours.* Additionally, 94% of people agree their skin looks radiant after using the mask.* Featuring hyaluronic acid, squalane, ceramides, Natural Moisturising Factors & more, the combination of humectants, emollients, and occlusives makes H.E.O. Mask an ideal barrier boost for skin adjusting to new levels of vitamin A. Enhance your routine by layering the mask with Hydr8 B5 Intense; this liquid hydration booster serum adds a further infusion of hydration to the skin, while the mask locks it in for sustained results.

How H.E.O Mask Works

Ageing, climate, hormones and more can trigger TEWL (transepidermal water loss) and dryness. Medik8 H.E.O Mask targets the symptoms of dehydration and dryness, whilst aiding the skin's natural barrier for better hydration over the long-term. Features of this mask include multi-weight hyaluronic acid, glycerin, NMF, glyceryl glucoside, blue sea kale, squalane, ceramides, linoleic acid and a breathable dimethicone barrier that locks in hydration.

The Science Behind Medik8 H.E.O Mask

Dry skin is a common complaint; exacerbated by extreme weather and busy lifestyles, it can be uncomfortable and take a toll on one's appearance. A weakened barrier leaves skin feeling sensitive, itchy, and vulnerable to the elements. Solving the problem is not an easy feat, with traditional creams often not potent enough to maintain proper levels of moisture. To tackle this issue, the Medik8 team took a step back and re-evaluated the three approaches to skin hydration: increasing water content (humectants), trapping moisture in the upper layers of skin (emollients), and reducing water loss (occlusives). Utilising all three means in a balanced ratio, H.E.O. Mask offers powerful, synergistic hydration.

Mask*. The perfect skin barrier boost for skins who are adjusting to new levels of vitamin A in their skincare regime.


Perfect Pair: Supercharge your results with Hydr8 B5 Intense. This liquid hydration booster serum can be layered with H.E.O. Mask, to add an extra infusion of humectants into the skin, while Step 2 of H.E.O. Mask locks in moisture for prolonged results.

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.

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.

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.

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.

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.

*Proven via independent clinical study on H.E.O. Mask. Tested on 35 participants over 4 weeks.

How To Use
After cleansing, apply as the last step of your evening skincare routine.

Smooth an almond-sized amount of Step 1 of H.E.O. Mask over face, neck and décolletage, avoiding the eye area.

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.

Apply 2-3 times a week or as required.
Patch testing prior to use is advised.

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.

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

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

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.
