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.
