It’s great for winter  and sensitive skin and doesn’t cause any pilling as it’s very like water . I enjoy this product and it does  what it says .

Nice but nothing special

3 stars out of a maximum of 5

I’ve been using this with my other products and it feels nice on my skin but doesn’t yet shout to me that it’s amazing. Maybe I need to use it solo for a few weeks to feel the benefits. Nothing wrong with it but was possible hoping to see a major difference.

Amazing

5 stars out of a maximum of 5

I bought this, as part of a few other things from this range & Inkey list. I like the idea of picking & choosing my own ingredients, based on what my awkward skin needs. I have eczema & am allergic to everything. My skin is incredibly dry & this has made my wrinkles look worse. This stuff is brilliant. It hasn’t adversely affected me. I cleanse, use rose water toner, then start with this as a treatment. I couldn’t be happier with the results. My wrinkles are reduced, as my skin feels hydrated & it prepares my skin for the next treatments I use. I use inkey co-enzymes, rosehip oil, then squalene oil from The Ordinary. I’m really pleased. I have tried everything & this has all had created better results than anything else I have tried, even things specifically for eczema & really expensive brands. Hope this helps someone

Lovely product

5 stars out of a maximum of 5

I love this product. It spreads very nicely just like water and can be used with any of my other skincare products. I use it twice a day every day after washing my face and sprinkling it with a spray toner.

Still early but no difference yet

3 stars out of a maximum of 5

I have been using this product for about 3 weeks, to calm and hydrate my face after a shower. It's still early days, but I haven't noticed yet any difference in my face. It just acts as a quick relief against the tightening/itchiness I was feeling after shower, but the result is not long lasting and I haven't noticed any other results yet. Will wait and see.

Great

5 stars out of a maximum of 5

Very watery but not sticky like some other hydrators. I didn't like TO hyaluronic acid and prefer to use this one with Hada labo hyaluronic acid, which is the perfect combo for dry and sensitive skin. I apply it morning and evening then apply moisturizer right after and let it soak in and it leaves my skin soft and hydrated all day.
