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.

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.

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

Rated 5 out of 5 by from Glow-Up Essential for Smooth, Plump, Youthful Skin [This review was collected as part of a promotion.] I absolutely love the Medik8 HEO Mask—it’s become a staple in my routine. It leaves my skin feeling incredibly smooth, visibly volumised, and gives such a beautiful, youthful glow by the morning. My complexion just looks fresher and more hydrated every time I use it. I also love combining it with Crystal Retinal—it really feels like a complete glow-up duo. The mask locks everything in overnight and enhances the results, so I wake up with brighter, plumper, more radiant skin. Honestly, I can’t recommend it enough. Love it!

Rated 5 out of 5 by from This is the nicest mask I have ever had [This review was collected as part of a promotion.] I got this free due to moving into the Crystal Deluxe on my points system, I am not sure I would of bought it otherwise, but this has been the best Mask I have ever used, using the gel and leaving for a few minutes and then putting the moisturiser on which locks in the gel, my face feels so nice after and have seen results of my hyperpigmentation fading, I will be replacing this once I have used this product up, I have only been using Medik8 since January this year and are loving these products and the results and just ordered some for my daughter.

Rated 5 out of 5 by from Fantastic duo [This review was collected as part of a promotion.] I love how this duo deeply hydrates my skin without feeling heavy. I tend to get oily skin and breakouts with rich moisturizer, but I have used this once a week for a month a the day after my skin is smooth and not oily
