Brightens Skin While Managing Slight Dryness

Kiehl’s Powerful-Strength Vitamin C Serum is light and easy to apply. It absorbs quickly into my skin without feeling sticky or heavy. At first, it made my skin feel a little dry and tight, but layering a moisturizer after helps a lot. After a few weeks of use, my skin looks brighter and more even. The texture is smooth, and it layers well under moisturizer. The serum has a mild citrus scent that fades fast. I like that it can be used both in the morning and evening. Over time, my skin feels healthier, a bit more plump, and less dull. It doesn’t cause irritation or breakouts, which is great for sensitive skin. Overall, it’s a simple, effective serum that helps improve skin tone and texture, while managing slight dryness with moisturizer.

A lightweight, fast-absorbing serum that brightens

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!

Cleared my skin up

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.

Génial.

Lisse le grain de peau et ne nécessite pas une grande quantité. L’éclat de la peau est revigoré.

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.

love it

love this product, its not too harsh on my face. no weird smell

Ottimo prodotto, ma packaging da rivedere

Il prodotto è davvero valido, ma perde parte del suo valore se venduto in confezioni di plastica. Considerando il prezzo, mi aspetterei un packaging più curato e sostenibile. Via la plastica, per favore!

Brightening, hydrating, and line reducing

I love love this vitamin c serum. This is the best one for my skin. I pair this with L’Occitane Immortal precious skin care line and it makes my skin plump and glowing.
