Best vitamin c

I have been using this vitamin C serum regularly and it really helps brighten my skin and improve texture. It absorbs well, layers nicely under moisturizer and sunscreen, and my skin looks more radiant with continued use.

Lightweight and fast‑absorbing

I’ve been using Kiehl’s Powerful‑Strength Vitamin C Serum, and it’s become one of my favorite steps in my morning routine. The texture is lightweight and absorbs quickly, so it layers beautifully under sunscreen. With 10.5% vitamin C (L‑ascorbic acid) and hyaluronic acid, it helps brighten my complexion, smooth fine lines, and fade dullness, giving my skin a noticeably more radiant and even tone over time. It’s strong enough to see results, yet gentle enough that my skin doesn’t feel irritated — even on days I’m also using acids or retinol in my routine. My skin looks healthier, more luminous, and smoother, and I can tell this serum really helps protect against environmental stressors too.

Helps with discoloration and uneven skin tone.

Loved this Vitamin C Serum. I have been suffering with discoloration and it has greatly improved that. I started once and day and built my way up to twice a day. So far am impressed and will repurchase

Awe yeah , this is totally worth the money and even better when you can get it buy one get one for free! I’m in the sun a lot and this sedum is so addictive ! It is nice and light and feels so nice on my face. I use the oil then the serum and I can feel it working its vitamins and magic into my skin! Sometimes when I’m traveling I share some with friends and they just loose their mind like what is that? Omg love it! ♥️ it’s truly my favorite Kiehls product ! And , after a day at the beach or snorkeling and you come take a shower and put your Kiehls on it’s like getting into bed with heaven . I love it ! 💜

Kiehl’s Powerful-Strength Vitamin C Serum

Before using it, my skin looked dull and slightly dehydrated. After about 3–4 weeks, I noticed my skin became brighter, smoother, and more even-toned. The scent is light and not overpowering, making it comfortable to use. The bottle has a simple but solid design, and the dropper makes it easy to dispense the serum. If you’re looking for an effective vitamin C serum, I think it’s worth trying.
