Lovely texture but easy to use lots

This serum has a lovely texture, it’s thick and feels nice on the skin. My skin felt moisturised but I wouldn’t say it was the best hydrating serum considering the price. Also, a warning that if you use the recommended amount listed, it’s easy to use up the bottle very quickly. I found the pipette was hard to measure a few drops, and often more comes out than needed.

Did absolutely nothing

I bought a whole range of Medik 8 products, including this serum, but it did absolutely nothing for my skin. I did not feel any hydration after applying the serum. Finished a whole bottle. Not worth the price, The Ordinary which cost 5 times less does a better job. Not impressed with this product.

Love this

Wonderful hydrating serum. Expensive but seems to work much faster and better than cheaper equivalents. A little goes a long way if you use over a damp face (misted with a hydrating mist first). Absorbs well without stickiness. Instantly hydrated skin that lasts a long time.

Best Use: Hydrating, Minimise Fine Lines & Wrinkles

Once of the best hyaluronic acids

Have really been loving this serum. It’s super hydrating and great for sensitive skin. The formula feels really nice on the skin and is fast absorbing. I use it day and night and it hydrates my skin wonderfully without breaking me out or making me oily during the day

Good HA serum

I've been shopping around for a good HA serum for a while now and this is the latest one I've tried. I like the slightly viscous texture of this one. I find it absorbs nicely after I wash and dry my face and don't have to wait long before I am able to layer my Vit C serum and moisturiser on top.
