desertcart.com: Kiehl's Powerful-Strength 12.5% Vitamin C Serum, Line-Reducing Concentrate for Face, Boosts Radiance & Firmness, Smooths & Plumps Skin, with Hyaluronic Acid, Dermatologist-Tested - 3.4 fl oz : Beauty & Personal Care

Review: Not greasy - Works for my skin making it tighter! Packaged well! Not greasy! Expensive but works
Review: Hands down the best vitamin C serum I've ever tried - 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 desertcart—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!

### ⭐⭐⭐⭐⭐ Its hydrating and helps with wrinkles
*by H***E on September 1, 2025*

Boyfriend loves this stuff. Hydrates around his eyes and keeps wrinkles at bay. Great quality ingredients. Smells nice but not perfume. Pretty expensive for the small bottle size you get but we're ok with that because it does work.
