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 642.
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.

Rated 2 out of 5 by from Initial Thoughts I will have to wait a few weeks to see the long term results. However, it is quite hard to wear from first impressions. The citrus smell is quite strong and slow to dissipate. It leaves a shiny and silky residue when you first put it on that doesn't really disappear, which is quite annoying because it brings out the wrinkles and texture in your skin.

Rated 5 out of 5 by from Amazing I bought the smallest size & it’s lasted me ages! My skin is rather dry but I have awkward acne too, I put a few pumps on my skin before bed & I wake up to the most beautiful radiant, glowing, & SMOOOTTTHH skin. Makes an incredible difference. My texture is really bad and this product is a total miracle, can’t wait to buy the full size :) totally recommend

Rated 5 out of 5 by from Really impressed I really like this product and have been using this for many months now (on my 3rd bottle now I think?). I use it morning and night after cleansing. A little goes a long way (1-2 pumps). I find all products like this work best when you also regularly exfoliate which I do about 3 times a week. This product leaves my skin very smooth and has had a significant improvement impact on fine lines and wrinkles. I plan on continuing to use this for a long time. Thanks Kiehl’s!

Rated 2 out of 5 by from Bottle #2 Being a new custom to kiehl's i was very excited to try the products and really like some of the other products. I have to agree 100% with some of the other reviews on this line reducing concentrate changed..I was so impressed with my first bottle and saw such a difference in forehead lines reducing and now my second bottle not the same and is not working and now the lines seem to be returning

Rated 4 out of 5 by from WOW It really works I tried some at an Ulta beauty shop and couldn’t believe within a couple minutes the lines under my eyes and forehead were 75% gone. I’ve tried many products and nothing has ever worked like this to get rid of wrinkles instantly. As far as the consistency I found it a little greasy but I would put up with that especially like the price value. My only complaint is the second ingredient is dimethicone and according to things I have read it puts a coating over your skin not allowing it to breathe. Why does Kiehls use this and not more natural ingredients in their products? I will stick with Anthony products because of the reason above. Otherwise I would’ve switched. I may decide to use it during the day and Anthony at night

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.
