This makes my skin feel soft and it has a warming effect.

I’m the kind of person who loves to explore different skincare products, always on the lookout for that ‘holy grail’ serum that can truly transform my skin. Over the past 10 years, while I’ve rotated countless brands—from high-end options like Sunday Riley and Dr. Dennis Gross to budget finds on Amazon—I’ve always come back to one consistent favorite: Kiehl’s Powerful-Strength 12.5% Vitamin C Serum. In the world of skincare, it's recommended to switch up your products every few months to keep your skin from adapting and becoming less responsive. This practice has led me to try everything from the surprisingly effective yet short-lived Brandefy serum (great on the first go but lost its magic by the second bottle) to La Roche-Posay, which was promising but oxidized way too quickly. Kiehl’s, however, stands out for many reasons. Its silky texture is a pleasure to use, and it boasts one of the highest concentrations of L-ascorbic acid—a hard-to-beat 12.5%! This is the gold standard for vitamin C in skincare, known for its potency and efficacy. My skin absolutely loves it. Regular use has visibly faded sun spots and smoothed out fine lines around my eyes and on my neck. I’ve seen some incredible results, and after all these years, Kiehl's Vitamin C serum remains my go-to. It’s a product I truly believe in and will continue to purchase. For anyone looking to invest in their skin, this serum is a must-try. Trust me, your skin will thank you!

It works to reduce the appearance of fine lines and deeper lines too. Kiehls doesn’t make one bad product and I’ve pretty much tried them all. I Guess that’s why they’ve been around 100+ years.

Purchased 75 ml for $49 in March hoping for visual improvements around eye area, and forehead. Although this isn’t the most expensive serum I’ve purchased, it’s also not the cheapest. I’m very disappointed as I haven’t experienced any improvements on my skin. The bottle I received doesn’t contain any shards of fiberglass as other reviewers. Definitely will not purchase again. 👎
