Everybody knows that HydroShield face serum is considered a staple in the Dr. Denese line, and there's a good reason for the buzz. It's a powerful hydrator and skin protectant, it seals in treatment toners or thinner serums, its matte and silky finish makes it appropriate for all skin types and is especially wonderful as a makeup primer. Oh, and it's packed with retinol. Here's a piece of info you might not know-- HydroShield fits into any skincare regimen. If you're like me and prefer to cherry-pick from different lines, you'll agree that this is a pretty important point. The texture of this serum works well when layered with oils, water-based serums and toners, creams, lotions, sunscreen and foundation-- no matter what you're using, HydroShield will only enhance your current routine. Believe it.
