MERME's Hyaluronic Acid Solution is formulated in its purest and highest concentration at 1%. This lightweight serum contains high and low molecular weights that deeply penetrate your skin for intense hydration and retention of moisture. Hyaluronic Acid is extremely hydrating and will instantly plump and firm your skin. It promotes smoothness, elasticity and supports your skin’s natural protective barrier. Once applied, it forms a lightweight film that holds moisture on your skin’s surface to promote smoothness, elasticity and supports your skin’s natural protective barrier.

Suitable for all skin types - extremely dry to oily skins will all highly benefit from hydration. Gentle enough for daily AM and PM use.

INCI: Aqua, Pentylene Glycol, Hydrolyzed Hyaluronic Acid, Sodium Hyaluronate

Quantity: 30ml

Odour: Scentless


Made with Pure Hyaluronic Acid.   Why a 1% solution? This mixing ratio is considered "pure" as it is the highest possible level of hyaluronic acid on the market and extremely effective. Products containing, for example, "75% hyaluronic acid" all have a 1% solution as an HA ingredient and are then further formulated.

Non-comedogenic, no: phthalates, surfactants, petrolatums, BHT, BHA, silicones, parabens, PEGs, sulfates (SLS/SLES), GMOs, mineral oils, petrolatum, synthetic colours, or animal testing.

What Makes it So Amazing? 

Hyaluronic Acid (HA) is the most hydrated biopolymer known and works as a connective tissue organiser with skin. For the outer layers of skin, a certain hydration level is essential for elasticity, smoothness and renewal. The lightweight film that HA forms on the topical layers of the skin also reduces irritating and negative environmental factors.

Its hydrating abilities are thanks to HA’s molecule structure that allows it to hold up to 1000 times its weight in water. HA is found naturally in all bones and cartilage structures of the body, however, this along with collagen and elastin, decreases with age resulting in drying and ageing skin.

For a hyaluronic serum to deliver both instant and long-lasting effects, you need a combination of molecular weights. Low weight hyaluronic molecules penetrate deeper into the skin’s structure, providing maximum below-the-surface hydration and in turn rehydrating skin cells over time (which helps to reduce fine lines and wrinkles). Whereas, high-weight hyaluronic molecules deliver immediate intensive hydration to the surface layers of the skin for an instant smoothing and firming effect.

You may remember that our skin naturally contains hyaluronic acid. Well, this combination of molecules of different sizes imitates the natural multi layers of the skin. Our intensive skin care offers an immediate plumping and smoothing effect, while also delivering long-lasting results and reducing fine lines and wrinkles in the long term.
