One of my Essentials
I love using this product between a cleanse and moisturizer. The combo of Vitamin C and the Hyaluronic acid is great as it simplifies my routine on days I don't have time to do a toner. Smells great, feels great. Sometimes its taken me a while to finish it, but the nozzle has never clogged nor the product dried out.

This review is from Kiehl's Since 1851 Powerful-Strength Line-Reducing Concentrate 3.4 oz.Vitamin C is a must 🍊🧡
I’m a huge vitamin C lover and this product packs a promising punch. Vitamin C is known to fade dark spots and improve skin brightness. I love that this serum is a little thicker than others that I have used. I noticed actual results in about 4-6 weeks (vitamin c takes a while to work). It blends beautifully on the skin underneath moisturizer.

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.

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!

This review is from Kiehl's Since 1851 Powerful-Strength Line-Reducing Concentrate 2.5 oz.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!
