Key Ingredients
Multi-Weight Hyaluronic Acid

H.E.O. Mask uses multiple molecular weights of hyaluronic acid (small, medium and large), to distribute deep hydration evenly throughout the skin's many layers. This leaves the complexion visibly nourished and supple.

Natural Moisturising Factors (NMFs)

A unique combination of natural components in your skin (sodium PCA, glycerin, urea, proteins, sugars, 15 different amino acids, lactic acid, and creatine) which bind and hold moisture for optimal skin hydration.

Ceramides

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

Squalane

An almost skin-identical lipid which helps to support the natural skin barrier by nourishing the complexion.

Frequently Asked Questions

When and how should I apply H.E.O. Mask?
You should apply H.E.O. Mask as the final step of your evening skincare routine. After cleansing, smooth an almond-sized amount of Step 1 of H.E.O. Mask over the 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. We recommend applying H.E.O. Mask 2-3 times a week, or as required.
Is H.E.O. Mask non-comedogenic?
Yes it is. H.E.O. Mask is non-comedogenic and therefore won't clog your pores.
Can I use H.E.O. Mask alongside Crystal Retinal?
Yes you can. Think of H.E.O. Mask as your nighttime moisturiser, so apply Crystal Retinal first (after cleansing and toning), followed by H.E.O. Mask.
