Kiehl’s Powerful - Sérum Concentrado Vitamina C

Soothing Vitamin C serum

It's too early to tell the results but the serum feels very soothing on my skin. I expect I'll be buying again.

I love this product!! I use it daily, now that my skin has built a tolerance. I love that it is a cream and not a serum. High percentage of vitamin C. As I am rubbing in my skin, I can see my wrinkles disappear. I have sensitive skin and this has helped immensely. .

Brilliant for under-eye circles

I'd found that Keihl's powerful vitamin C eye cream was the only thing that alleviated my dark undereye circles--until I realized that this product was almost nearly as effective and a significantly better value. I use AHAs but no retinols and have acne-prone, moderately sensitive skin (reacts to some stuff, not to others) and have never had any issues with this product.

Not my favorite

I really didn’t like this product. It’s called a serum but it’s a cream with a silicone (I think) base. It didn’t play nice with my other skin care or makeup. not what I was expecting for a Vit C serum

Noticeably improves dullness, wrinkles, texture

I just purchased my second bottle and I love it. It's very hydrating and I notice a difference if I skip it. I do have sensitive skin and am prone to acne, but I never experienced any irritation or outbreaks like others have. I also don't feel the smell is that strong? All I can say is, if you're on the fence and have the opportunity to grab a sample give it a try. If you aren't one of those who find it irritating, it's likely going to be life cha going for you.

This product is too strong for someone with sensitive skin. I do not recommend it, it burned my face

My Skin Has Never Looked Better

My mother recently said my skin has never looked better, and I attribute that in large part to this product. I've been using it for about 2 years, twice a day.

Caused major breakouts

At first, I liked this product because it went on very smooth. However, after using it for 2-3 days my skin has broken out with several small and large whiteheads and I haven't had acne in years. SO disappointed with this product and still working to restore my skin back to normal after a few days of stopping the Keihl's product.

Not for me.

I didn't like how this felt on my skin. It felt sticky and looked shiny. I will be returning. It's too bad, because the packaging is ideal.

Please don’t buy if you got acne prone skin

This product is over hyped Is not that great and it will clog your skin it clogged mine thankfully I was able to return it I will never ever buy it again… I’m still dealing with the breakouts

No difference after finishing bottle

Just finished this bottle after months of daily use and I can’t say I’ve noticed really any difference in my skin. I won’t be repurchasing

Too much dimethicone for a serum

I want to love this product, as the Khiel’s ultra repair cream is my GOAT moisturizer, but I’m so confused by the high amount of dimethicone. It’s one of the first ingredients, so the serum applies and feels like a primer. I’m not opposed to silicones, but they’re not something you want tons of in a serum because they interfere with the absorption of subsequent steps like moisturizer. Wearing this plus my usual moisturizer on a humid day is impossible, my face just sweats. I have to apply this as part of my PM skin care routine to avoid that, so I’m not able to get the full benefit of the vitamin C. I won’t be repurchasing. On a positive note, this did not upset my sensitive and perioral dermatitis-prone skin.
