Hyaluronic acid is a natural moisturizing factor (NMF) that can bind up to 1000 times its own weight in water. This formula focuses on ultra-moisturizing high-molecular-weight versions for ample surface hydration as well as on medium-molecular weight versions, whose strong point is to strengthen the skin barrier and to reinforce the skin’s natural defense & healing mechanisms.

Ingredients & Research

key ingredients:

Sodium Hyaluronate Crosspolymer A new generation, cross-linked hyaluronic acid, whose water binding ability is several times greater than the already amazing water-binding ability of hyaluronic acid. Also offers longer-term moisturizing benefits.

Sodium Hyaluronate - The most common, salt-form of hyaluronic acid that can be found in large and medium molecular weight in the formula.

Tremella Fuciformis (Mushroom) Extract – The extract of silver ear mushroom known for its amazing water-binding abilities. It contains sugar constituents, including Glucuronic acid, one of the building blocks of Hyaluronic Acid. It is cosmetically very elegant, non-sticky, and has additional antioxidant benefits.

Hydrolyzed Hyaluronic Acid – A smaller molecular weight version of Hyaluronic Acid that is known for its ability to reinforce the skin’s natural defense & healing mechanisms.

Panthenol – A classic skincare ingredient that is a reliable soothing, moisturizing and skin-protecting agent.

Customer Reviews

I love using this serum on both my neck and my face both AM and PM. It still allows me to wear layers over the top and my moisturiser and sunscreen don't slip even when I'm in Singapore in humidity. I love it but this winter while I'm in the cold I'll be trying the rich version.

Great for everyday

The light formula is amazing for me, I tried to mix in with creams, but I find it works better for me used alone. I usually apply it before my spf, and skip the day cream, or I use it at night on sensitive areas when I am applying retinoids. It also last quite a long time a small amount is enough for my entire face/neck area :)

HA Light serum

I’ve tried so many HA serums from well-recognised brands and can confirm that this is the best by very far!! I am in my late twenties and starting to feel changes in my skin elasticity yet still suffering from acne, and this is the only serum that works perfectly for my skin, gives it an amazing healthy glow and yet doesn’t feel too greasy nor clogs my pores. It is also extremely good price for value, and the customer service is amazing! I would highly recommend trying it.

Love it

Very light and non sticky serum


My face feels hydrated and smooth after using it. I have been only using it for a month and not every day since after buying it I heard a dermatologist on youtube saying hyaluronic acid is actually bad because it holds on to water and not let the skin absorbs it. Nevertheless, its size dictates its function and this product here has a balanced structure and has Glycerin (which is also good for hydration) before hyaluronic acid in the ingreditents list which makes me feel a bit safer using it in case that info is correct.
Thank you.
