  • Step 2 is a nourishing cream which is infused with squalane, ceramides and dimethicone to help enhance the natural skin barrier function; locking moisture into the skin for long-lasting hydration.

Wake up to visibly supple and youthful skin, with a complexion that feels intensely moisturised and thoroughly nourished.

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.


Key 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.


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.
