Brightens, firms, and smooths — a must-have serum

The Kiehl’s Powerful-Strength Vitamin C Serum truly delivers visible results! The texture is silky and absorbs quickly without feeling greasy or sticky. After just a few weeks of use, my skin looks brighter, smoother, and more even-toned. It really helps to fade hyperpigmentation and soften the look of fine lines. I also love the slight warming sensation upon application — it feels like the vitamin C is activating instantly. My skin feels firmer, fresher, and has that healthy glow I’ve been looking for. Definitely one of the best vitamin C serums on the market!

I love this product

Anything Kiehls brand is going to be a wonderful product. No matter if it's this one or anything else in their product line. I personally like this because I have dull skin, and I also have large pores, and it has really, really helped solve some of those issues. It is a little pricey, but you get what you pay for with it, and it does work. I am not too crazy about the smell, but that's just me.

Uncomfortable to put on

Feels like putting tiny glass shards on my face. I see other reviews saying it’s smooth. Mine definitely isn’t.

For people who wants to lighten the skin tone

Kiehl’s Vitamin C Serum is a fantastic addition to my skincare routine. It absorbs easily into the skin without leaving any greasy residue, making it perfect for layering under moisturizer or makeup. After a few weeks of use, my complexion looks noticeably brighter and smoother, with a healthy glow. I also appreciate that it feels gentle, even on sensitive skin. Overall, it’s an effective, lightweight serum that delivers visible results and makes my skin look more radiant and even toned.

Perfect

The Kiehl's Powerful-Strength Vitamin C Serum is a potent antioxidant concentrate formulated for the comprehensive improvement of skin condition. The product targets primary signs of aging, including loss of radiance, uneven texture, wrinkles, and enlarged pores. The key feature of the formula is its high concentration of 10.5% pure Vitamin C (L-Ascorbic Acid) combined with 2% Ascorbyl Glucoside, ensuring a prolonged and stable effect. Vitamin C is a vital component for stimulating collagen synthesis, brightening pigmentation, and protecting against free radicals. The unique anhydrous formula guarantees the stability of the Vitamin C and its maximum efficacy.
