Different texture

I have used this product for years but my latest bottle is different. It feels rough to my skin like an exfoliated.. Not the same. Will try something new.

Atrocious

I think they pay for reviews and remove negative ones. This product is terrible. I used it for two days. Two days. On the third day I woke up and my under eyes were extremely puffy, red and wrinkly and irritated. I was so horrified. The way it looked scared me so bad I’ve never felt so terrified for my health and appearance before. There are multiple reviews like mine. This product needs to be removed from the shelves.

For bright looking skin use this serum

This serum is game changer for me. It brightens skin tone from dull to young look. It also reduces black spots from sun damage skin as well as reduces wrinkles.

Probably the best vitamin C serum

It was good for my sensitive skin. Unlike many other vitamin C serums, it wasn't sticky and absorbed so easily. It's really hydrating and moistorizing, I liked it. It may not be big enough in the standard size, but I was happy overall.

A potent vitamin C serum that brightens and revita

Absorbs quickly and one bottle lasts several weeks with daily use.Brightens skin tone and improves radiance over time. Great choice for dull skin and antioxidant boost. Some users may experience mild tingling but not lasting redness. Generally well-tolerated; rare irritation for sensitive skin.

My go-to Vitamin C serum for life

My absolute favorite Vitamin C serum. It goes on so nicely with no icky sitckiness. A single pump is all you need and it absorbs beautifully and goes on so smoothly. I have used other vitamin C serums but none are as easy and pleasant to use as Kiehl's. I follow this with my Kiehl's Ultra Facial Cream which is a lovely complement to any active serum. Lastly, I think this is very good value for the volume.
