Birchbox Breakdown

You’ve aced Skincare 101: You drink plenty of water, log eight hours of sleep a night, and diligently apply (and reapply) SPF. But to get your advanced degree, you’ll want to invest in a targeted antiaging serum like Kiehl's Powerful-Strength Line-Reducing Concentrate. Loaded with vitamin C and other potent ingredients, it smooths, brightens, and tones skin. Get ready for your best skin yet.

How it Works

The star of this formula is a hefty 10.5 percent of pure vitamin C. Our go-to antidote for an unshakeable cold is also a potent antiaging ingredient that smooths fine lines, brightens unevenness and also protects from free radicals. In addition. glycerin keeps skin hydrated and balanced. Bonus: this ace skin firmer has been shown to improve elasticity by 32%.

How to Use

Apply morning and night to clean skin. Avoid the area around your eyes. It’s normal to feel a little tingling from the vitamin C.

Worked wonders!

Although the directions indicate not to apply around area, I read them a little too late and wound up doing just that. I did notice that after just 2-3 days the difference in the fine lines I get underneath my eyes were less noticeable.

Very Nice Product

I was very happy with this sample. The texture of this product is really nice and silky. I used it once or twice a day under my moisturizer and noticed a difference in my wrinkles.

In Love!

I have a mid size deeper wrinkle on my forehead between my eyes. I used this just on the area of deeper wrinkles. They disappear. I use it in am and pm ....concentrating directly on wrinkle/trouble spots.

Couldn't tell a difference in lines

I'm 31 and starting to get some smile lines around my eyes. I was happy to get this sample and I used it every night until it ran out. It felt soothing and nice around my eyes, but I didn't really notice a difference in the appearance of lines. It did feel nice and warm going on though, so I'm sure it was doing something -- maybe preventative for further development of line, but I couldn't really tell. Maybe if I'd used it longer.

Heats up

I loved the fact that it heats up as you apply it.
Seems to really get in there instead of just laying on your skin all day and never really doing anything

no difference

i used this sample for a few months (i was only using it on one forehead line) but it made no difference as far as i can tell. i was using it once a day at night. im only 26 so its not like i was hoping for a miracle just a slight reduction in my only wrinkle lol.

Buttery smooth

This is now part of my nightly routine. It is the softest, most buttery smooth under cream that I have used. It goes on like velvet. So happy to have discovered this.
