Triggers Pimple Breakout EveryTime.

I love Kheils products BUT the Vitamin C Serum makes me break out with pimples every time I use it. I don’t have a breakout or pimple problem generally and have gone stretches without using the serum to see if in fact the serum is the trigger. And unfortunately it is. Every time I use it I am assured to wake up with pimple. Bummer.

Great Product

Results from this product are very gratifying. I purchased to minimize fine lines and dark spots. The forehead lines? I’m very pleased they are disappearing after 2 weeks of using 2x/day. The dark spots may take a little more time. Overall a great product for my use, I’m also experiencing some slight firming in my problem area (forehead). We’ll repost more results after a month. I’m Happy I purchased this product

Love the hydration!

A delightful serum that hydrates and smoothes my skin. My skin looks better and I have used it for several years. Of course, drinking water always helps too!

Reformulated, unfortunately

I have been using this serum for several years. It was recently updated and appears white instead of the usual yellowish color. Also, the tingling sensation is gone. Wish the ingredients would have remained the same.

Fast-absorbing Vitamin C serum that brightens, smo

The Kiehl’s Powerful-Strength Vitamin C Serum has been amazing for my skin! The texture is silky and smooth, and it absorbs quickly without feeling greasy or sticky. I love that it layers well under moisturizer and makeup. It has a light citrus scent that feels fresh but not overpowering. The packaging is practical with the pump, which makes it easy to control the right amount of product and keeps it hygienic. In terms of effectiveness, my skin looks brighter, smoother, and more even-toned after consistent use. Fine lines are less noticeable, and it gives my skin a healthy glow. Definitely a staple in my skincare routine!

Part of my morning routine

I am not a fan of putting too many products on my face especially in the morning when there’s just so many other things to do. I limit it to 4-5 products and this has to be part of that routine!

Love it

I used this product in my daytime routine and was really happy with it. Just a little reminder whenever you use this or any kind of vitamin C serum, don’t skip your sunscreen! Your skin will look radiant, like glass. I used to keep it in the fridge, and I loved that cool sensation on my skin every time I applied it.
