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 with foundation for a dewy finish. While most praise its moisturizing properties, some note a strong scent and occasional pilling with other products. The texture is described as thicker than similar serums, with users particularly appreciating its performance during dry weather. Common feedback includes its compatibility with other serums and its plumping effect on the skin.

    Perfect mixed into make up

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