A bit disappointed

3 stars out of a maximum of 5

Order this after seeing the reviews but hasn’t met my expectations. Having dry sensitive skin, it doesn’t sit well on my skin. On the positive side it never broke me out or create dry patches,...I just need to find another way to use this product for it to work well for me

Great final step or primer

5 stars out of a maximum of 5

I mix this with NIOD photography fluid opacity serum as the last step in my routine and it leaves my skin looking smooth and glowy, and definitely helps to lock in moisture. It does have silicones in it, but for me, that aids its performance as a primer before I put my foundation or tinkered moisturiser on top. I can not recommend The Inkey List products enough, absolutely brilliant!

I absolutely love this product and I'm back to buy another. I used it morning and night and I genuinely see results. My skin is softer and plumper. I use it in conjunction with another brand hyaluronic acid (which I'm not a fan of so will try Inkey List when it's back in stock!). I like the consistency, it applies really smoothly and isn't sticky. I love it so much I pulled the lid off to scrape every last bit!

Alcohol smell

1 stars out of a maximum of 5

I don't like the consistency of this product . As soon as I apply it to my face it dries up. My face doesn't look or feel any more hydrated/moisturised than usual and the worst is a strong alcohol smell.

I never ever leave reviews but this has SAVED my skin!! I have dry-normal / sensitive skin and have issues with eczema too! This has plumped my skin and has completely repaired my moisture barrier / hydrated my skin! So amazing.

So hydrating!

5 stars out of a maximum of 5

I have dry/ dehydrated skin and usually suffer from patches of eczema on my face. This has honestly changed my skin for the better. I use it straight after The Ordinary Hyaluronic acid to maximise the hydration benefits. It has a very thick consistency, so I'm not sure how good it would be for oily skin, but if you have very dry skin I couldn't recommend it enough!

Polyglutamic Acid

5 stars out of a maximum of 5

I cannot speak highly enough of this product, I struggle with dry skin and also have psoriasis, so have to be careful what products to use on my face. I have been using this acid for approximately 6 weeks, my skin has really improved.
