You've never met a smarter serum

In case you haven’t noticed, your skin’s needs can change from day to day or week to week. One day it may be dry or sensitive, and then it’s in great shape the next. If you’re a true beauty junkie, you probably have different products to address these ebbs and flows as they arise—but what if one serum could do it all and adjust to give your skin exactly what it needs every day?

This might sound too good to be true, but this is exactly what Dermalogica’s Smart Response Serum does. Sure, it’s designed to target wrinkles, dehydration, dark spots and redness with four unique actives—but only if it detects a signal that your skin needs it.

These aforementioned actives are hydrolyzed beta glucan (for hydration), hydrolyzed wheat flower (for skin tone), gallic acid derived from the Japanese cornelia cherry (for redness) and mannose (for wrinkles and firming). Even if this doesn’t mean anything to you, trust me, this is good stuff—and Dermalogica is all about effective, professional-grade products.

I’ve been using one pump every morning for almost a week and my skin looks amazingly happy and healthy. (As with most skincare products, it takes four weeks to see significant improvement so I’ll be sticking with it.) You can use it in the morning and/or evening—but Dermalogica says not to layer it with other serums, and to only use it in the A.M. if you use retinol at night. (Don’t worry, the product does not cause sun sensitivity.)
