Kiehl's Since 1851 Powerful-Strength Line-Reducing & Dark Spot Reducing Vitamin C Serum
Community verdict
Kiehl's Powerful-Strength Line-Reducing Vitamin C Serum earns praise from many buyers for its ability to brighten skin, fade dark circles, and improve elasticity over consistent long-term use. Satisfied users often note that it delivers a noticeable glow and smoother texture without the typical sting of other potent vitamin C formulas. However, several reviewers caution that it requires weeks to show results, feels expensive for the amount provided, and can trigger severe breakouts due to its silicone content.

The tester has been the first time I’ve experienced the “vitamin c glow”, I was so impressed and happy.
With consistent use I began to see results within 4-6 weeks. My dark circles are pretty much nonexistent!!!
I bought the powerful strength line reducing concentrate with vitamin c and used it for about 2 weeks before my face broke out really badly
So I thought I would try this because of small lines on forehead eyes mouth... I have seen no difference. I have been using for about a month now.
