It’s promising

I was given this as a sample so I didn’t have enough to use for a long time, but it stuck with me. The texture is silky and absorbs quickly without feeling sticky or heavy, and it layers well under moisturizer and sunscreen. A little goes a long way, and it fits easily into a simple morning routine. Overall, a solid, well-formulated vitamin C option, make sure to hydrate after if you use topical Tretinoin also.

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
