A lightweight, fast-absorbing serum that brightens

Kiehl’s Powerful-Strength Vitamin C Serum has a smooth, lightweight texture that absorbs quickly without leaving any sticky residue. It has a subtle, pleasant scent and feels refreshing on the skin. With consistent use, my skin looks brighter, more even-toned, and feels firmer. The serum layers well under moisturizer and makeup, making it easy to include in a daily routine. Overall, it delivers visible results and feels gentle and effective, offering great value for a high-quality product.

Wow

I recently tried Kiehl’s Since 1851 Powerful-Strength Vitamin C Serum, and I really love it — it’s just the kind of serum that feels both potent and gentle, which is exactly what I was looking for. From the first time I applied it, I could feel a slight warmth, which tells me the vitamin C is active, but it didn’t sting or irritate my skin. The texture is light and gel-creamy, so it spreads easily and absorbs quickly. It doesn’t leave a sticky residue — just smooth, healthy-feeling skin. After using it consistently for a few weeks (morning and night), I’ve definitely noticed a brighter tone. My skin looks more even, and pigmentation spots have softened. There’s a subtle glow now — not shiny, but luminous in a natural way. Fine lines, especially around my forehead and under my eyes, seem a little less pronounced too. Another thing I appreciate is how it layers under other products: I apply a moisturizer and sometimes a face oil afterward, and everything sits beautifully — no pilling or weird texture changes. Also, the packaging is sensible — it comes in a dark bottle to protect the vitamin C, and the dropper dispenses just the right amount. I feel like I’m getting a quality product that’s designed to work well. Overall, Kiehl’s Powerful-Strength Vitamin C Serum has become a staple in my routine. It’s strong, effective, and makes my skin look more vibrant and youthful — exactly what I wanted from a vitamin C treatment. Highly recommend it!

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.
