Product Description

Wake up to a visibly glowing, plump and intensely hydrated complexion with this two-step overnight treatment mask from Medik8.

Taking an innovative and scientific approach to optimum skin moisturisation, H.E.O Mask delivers clinically proven skin hydration, barrier support and moisture retention (both instantly and overtime).

Expertly formulated with the three key pillars of moisturisation - humectants, emollients and occlusives (which make up H, E and O), are combined in an expertly optimised ratio to significantly improve the look of dullness, dryness, fine lines and wrinkles while you sleep.

With H.E.O Mask, you can expect to wake up to your most supple-looking, deeply hydrated skin.

Multi-Weight Hyaluronic Acid
H.E.O Mask features multiple molecular weights of hyaluronic acid (small, medium and large), to evenly distribute deep hydration throughout the many layers of the skin - leaving it visibly supple and nourished.

Natural Moisturising Factors (NMFs)
A combination of natural components within your skin (including urea, proteins, 15 different amino acids and lactic acid) that bind together and lock-in moisture for deeply hydrated, moisturised skin.

Ceramides
Naturally found in the skin, ceramides work by mimicking the natural lipid barrier to deeply nourish and replenish the complexion.

Squalane
A near skin-identical lipid that helps to support the skin’s natural barrier for a nourished complexion.

Glycerin
A natural humectant which traps moisture within the skin to leave it comfortable and hydrated.

Rated 5 out of 5 by from Plumps up my skin without breaking me out [This review was collected as part of a promotion.] I was hesitant to try this mask as I find oily and thick layers cause break outs for my skin. However, both parts of the mask feel light, and absorb super quickly. They aren’t at all greasy. Its a great hydration boost for my skin and has made a great difference in my routine twice a week

Rated 5 out of 5 by from Hydrated Glowing Skin [This review was collected as part of a promotion.] I work 12 hour day & night shifts, I used to look in the mirror & think my skin was tired, full & dehydrated. I wanted a product to add the hydration back but everything I tried only gave me short term results. . I started using Medik8 in February this year & all I can say is wow! After only a month my skin was glowing & this is everyday not just temporary results. My skin no longer feels tight & I've never had so many complaints. I had a facial recently & the therapist said my skin was like glass. . I use mostly Medik8 products including cleanser, liquid peptides advanced, Eco PDRN, C tetra luxe, total moisture cream & crystal retinal. I have just added this mask to my routine, I use it 2-3 times a week on non retinal nights, it's amazing, I wake up looking well rested & deeply hydrated. This is going to be a staple part of my routine from now on.

Rated 5 out of 5 by from I love this product, I [This review was collected as part of a promotion.] I love this product, I wake up with soft skin and use it almost every night now, a tiny amount goes a long way covering my face and neck. I will be purchasing again.

Rated 5 out of 5 by from My Skin Loves This [This review was collected as part of a promotion.] I've been using the H. E. O. Mask a few times a week for a while now, and I've genuinely noticed a difference when I wake up the next morning. My skin feels deeply hydrated, looks healthier, and my make-up always seems to sit so much better the following day with a lovely glow. It genuinely feels like a mask that *does* something, rather than one that just looks nice or feels luxurious to apply. I use retinal regularly, and I think this is the perfect complement—it helps keep my skin feeling nourished, hydrated + balanced without feeling heavy.

Rated 5 out of 5 by from Definitely One to Keep [This review was collected as part of a promotion.] Thought I would give this product ago and after only one use I know it's going to become part of my weekly skincare regime, my skin felt and looked great afterwards

Rated 5 out of 5 by from Face like silk [This review was collected as part of a promotion.] This is so lovely and skin feels so silky immediately. So great after using retinal the night before.
