Reviews Summary
Customers say this serum has a silky, smooth texture that glides easily onto skin. Many reviews mention enhanced hydration and a dewy, glowing finish. The product works well under makeup, with several users mixing it into their foundation for better application. While most praise its moisturizing effects, some note a strong scent and occasional pilling with other products. Common feedback includes soft, plump-feeling skin after use. A few users report issues with the pump mechanism, though most find the product's consistency ideal - neither too thick nor too thin.

    Long time use

    I have been using this product for so long I am not sure I can adequately review the product. What I can is that the serum has been a regular product in my daily routine. I love the results I get with The Inky List products since the serum is part of my daily routine I definitely can recommend it

    Awesome Hydrator

    I love both the consistency and the results of this thicker than water serum. I put it on after my other watery serums and my face is more hydrated with consistent use. It has no fragrance and great ingredients.
