Drying & Irritation: A little bit irritating, but it doesn’t last

I’ve definitely experienced my fair tóm tắt of irritation from skincare products like retinol, which have left me with this tight, dry stinging feeling. The first time I used Kiehl’s Powerful-Strength Line-Reducing Concentrate it didn’t bother me at all, but as time went on & I continued khổng lồ use it morning and night as directed, I noticed more irritation happen in the size of a bit of a sting when I put it on.

The good news is that it doesn’t last. Unlike with retinol where my face would sometimes feel dry và irritated all day, the irritation only happened when I first put the Kiehl’s Powerful-Strength Line-Reducing Concentrate on. If your skin gets irritated easily, though, you may want to lớn steer clear of this one.

The Results: Brighter và smoother, as promised

Before writing this review, I spent two weeks testing the Kiehl’s Powerful-Strength Line-Reducing Concentrate both morning and night after cleansing & before moisturizing.

While I can’t say I saw my fine lines disappear immediately, within a week I noticed that my skin was more radiant and that some of my dark spots had gotten a bit duller.

My skin looked smoother overall, and when I touched it felt softer and more even—no annoying rough patches.

I’m hopeful that using this over time will reduce the appearance of fine lines và wrinkles, & hopefully prevent more from popping up. Thanks to the lack of irritation and early results on my skin, there’s no way I’ll stop using it.
