Reviews Summary
Customers say this serum has a silky, smooth texture that leaves skin feeling soft and hydrated. Many reviews mention its effectiveness under makeup and ability to mix well with foundation. Common feedback includes praise for its moisturizing properties and plumping effects. While most find it absorbs well, some note a strong scent and occasional pilling with certain product combinations. The serum pairs particularly well with hyaluronic acid according to frequent users. Reviews indicate it works especially well for dry skin types, though a few experienced texture issues or sensitivity.

    Does the Job

    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.

    Hydrating

    A very light and hydrating serum. Perfect combination with Vitamin B C and E moisturiser ending with Polyglutamic Dewy Suncream.
