DRYING!

1 stars out of a maximum of 5

I don't understand these products! This and the hepta peptide are sooooo drying. I have mature combo skin and now my skin is parched! Seems like it's actually pulling all of the moisture from my skin, even after using rosewater before AND after. And it does not work well under makeup. Am I doing something wrong?

It did what?

2 stars out of a maximum of 5

After reading rave reviews about this acid I was quite disappointed - after 2 weeks of daily use it appeared to actually dry my skin out as opposed to retain moisture which it is meant to do. My skin is no different apart from being drier, so not good for me and (yet) another futile purchase.

Unusual, extraordinary hydration

5 stars out of a maximum of 5

Don’t get me wrong, this product is bizarre. Quite thick and silicon like - but wow. Incredible hydration with a completely matte finish. I use it after all my other serums and hyaluronic as a last step. It created a truly airbrushed, matte, flawless finish whilst locking in all the goodness and moisture from your other products. Looks fabulous under makeup too - just don’t apply too much. Innovative, extraordinary - inkey list: I salute you

Silicone, silicone, silicone

3 stars out of a maximum of 5

Was excited to try this but it doesn’t work the same way as hyaluronic acids I’ve used. It’s a very slippy/silky (aka silicone heavy) gel that just feels like a primer to me. No hydration effect whatsoever. It just seems to work by forming a silicone barrier. Just another silicone laden disappointment from this brand for me.

Very nice fragrance free hydrating serum.

4 stars out of a maximum of 5

The Polyglutamic Acid applies easily, absorbs quickly, and sets to a nice finish. This can fit into any routine very easily. I recommend applying this after other serums but before moisturisers. If you are looking to add some additional hydration into your routine this is a nice and affordable option.

This is the bomb!

5 stars out of a maximum of 5

Never have I gone so long without even the tiniest bit of dry skin!! I'd heard amazing things about hylauronic acid having moisture retaining properties but it didn't do as much as I'd hoped for on my dry skin...but this stuff?! OH.EM.GEE. it's frickin incredible!! I've just bought another 4! One for each of my daughters, my mum and a spare for me!

THIS IS UNREAL

5 stars out of a maximum of 5

THIS IS INCREDIBLE. I have combination leaning oily skin so am always worried when using products aimed toward drier skin. But this is super hydrating and has possibly the nicest texture I have ever felt. Goes on like velvet and skins into the skin beautifully. Amazing for under makeup, skin had that soft matte look to it, definitely helped with it lasting longer too! Cannot recommend this enough, so happy 10/10

THE BEST SERUM EVER!!!

5 stars out of a maximum of 5

This is amazing!!!I never had such an amazing impression after using a serum. So I am using first the Hyaluronic acid from them or The Ordinary or Mixa, then I use more serums from them and The Ordinary(niacinamide, q10, matrixyl, alpha arbutin, acids, retinoids etc, not all together, some in the morning or evening or alternating) and then I apply this at the end. The feeling of this serum is the best and the skin feels so good after. I also apply a moisturiser or oil after this. It has a silicone texture which many people hate (they think it's bad for the skin when actually any silicone protects the skin forming a barrier and doesn't let the skin get dehydrated). I am almost done with med school and I want to do dermatology so I am reading a lot about ingredients.I will repurchase forever!

Amazing results!

5 stars out of a maximum of 5

My skin had been dehydrated for so long, it felt awful and sensitive and was breaking out everywhere. i’ve been using this morning and night (2 pumps) for 4 days and I’ve seen a huge huge improvement in such a short amount of time. My skin looks clearer and brighter and feels softer and plumper. So happy and so excited to see the difference with continued use!!!
