soft silky skin
I have been using this serum for a while now, alongside other Inkey products.
My skin feels soft and supple and plumped, and I get a lot of compliments on how my skin looks.
I'm so glad I discovered the Inkey range of face products.

I contacted INKEY for a recommendation to help keep my skin hydrated in the colder winter months and they suggested this serum. I use it after my hyaluronic serum to seal in moisture and have found it does exactly that.
The only reason I gave 4 stars and not 5 is the smell. The smell reminds me of nail varnish remover, it’s not that bad and you get used to it but smells a bit chemically. No scent would be great.
