HERITAGE HIGHLIGHT

HERITAGE HIGHLIGHT

Kiehl’s chemists stabilized 10.5% Pure Vitamin C in a water-free formula more than 13 years ago and became pioneers in Vitamin C skincare products. Now, our formula includes 12.5% Vitamin C and Hyaluronic Acid.

Powerful-Strength Line-Reducing Concentrate is rated 4.5 out of 5 by 648.
Rated 1 out of 5 by from batch code discrepancy Batch code on packaging does not match the code on the bottle. I ordered directly from this website. Although both numbers say the product is still good, the error is concerning.

Rated 5 out of 5 by from amazing! I honestly cant live without this stuff! for years I've tried everything and spent so much money on skincare and this is the only one I see results with. I have a deep wrinkle in the middle between my eyes and this literally smooths it out so much and people comment on how nice my skin is. I dont wear foundation anymore because I dont need too. if this stuff ever stopped, I dont know what I'd do!

Rated 3 out of 5 by from Acne scars Young black woman with hyperpigmentation: I bought this because it contains vitamin C, which I was told (by the salesperson) would lighten my acne scars, even though that's not how it is marketed. Having used it for a month now, I can say that whilst my skin definitely looks brighter overall, it hasn't done much for my scars.

Rated 5 out of 5 by from Great face serum! Tried a sample and then switched to this from the Age Defender serum. Much more effective. Really kind of revealed the underlying and fresh skin. I’m apply twice a day followed by Facial Fuel over it. Only been using for a couple of weeks now but very impressed so far. Best Kiehls product that I’ve used to date.

Rated 5 out of 5 by from Can see results already! As a very fair skinned person living in a tropical country, I've become concerned that my skin is ageing fast.I have had to have laser for spider veins round my nose and was going to do the same for melasma. I was loathe to initially buy the product as it seems very expensive here in Thailand But it has been money well spent.Since I've been using this product my skin seems to have softened, pores and age spots don't seem to be as obvious, and my skin looks calmer (not as blotchy and red). I've just bought my second bottle and rarely review products but felt like this is clearly effective and so deserved a mention.

Rated 5 out of 5 by from 5 star product 1 star pricing policy Re: Powerful-Strength Line-Reducing Concentrate pricing. I love this product and have used it for several years. I was really happy to see it now offered in a supersized bottle however I am confused and disappointed that the price per ml of the 100ml bottle is much greater than the price per ml of the 75ml bottle. This is illogical and goes against the standard practice of better value for larger bottles. The lovely shop assistant told me that she and the other staff also thought this was odd and not good and advised me to send in a customer complaint/query as apparently you do take note.

Rated 1 out of 5 by from Nothing changed, waste of money. 30 days later I saw zero change. I’m so tired of false claims I took a pic before then again 30 days later. It does not work at all. Too pricey at any cost for zero results. what I’d love to see is a 55-60 year old model! I didn’t have even fine lines at 45 and you’re using someone who’s “almost” 40, this is a joke. I have pretty good skin but not even a change in the finest of lines. No thank you!

Rated 5 out of 5 by from Fantastic feeling and smell on the skin I had a sample and bought the full size as it was so wonderful. Amazing orange peel smell. Immediately softens and yet the skin feels firmer. An absolute must buy to use morning and evening before your moisturiser. A pea size is all that is needed so is great value too.

Is it safe for a teen to use?

Asked by: Yanny
Hi there! Thank you for your interest in our Powerful-Strength Line-Reducing Concentrate. Vitamin C levels deplete in skin over time, so using skincare products with Vitamin C is important as you grow older. However, these formulas are still effective to use before you start to see fine lines and wrinkles. These formulas help boost radiance and provide antioxidant protection to help defend skin from early signs of aging. However, always consult with your dermatologist when incorporating new skincare products into your routine especially for someone with less mature skin.
