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.

    Perfect mixed into make up

    I love adding this to my foundation to make it extra moisturising and dewy. Lovely on its own too.
