Great serum for uneven n wrinkled skin

What a lovely serum! I have been using this serum on n off for the last 4 years now and I have to admit that's this one is the best vitamin c serum in the market. It has worked v well for my pigmented skin n reduced my uneven skin tone! Love the smell n v easy to apply. It's has a bit thick texture so make sure u apply evenly onto your skin before applying your moisturiser or SPF. 12.5 is a good strength to achieve great results but apply every single day to see the results! A must have product!!

Caused a breakout of spots !

I liked the feeling of this on my skin but after using it for a few days I started getting a breakout of spots all down one side of my face and on my forehead ! Immediately stopped using it and after 7-10 days my face had cleared up. I tried using it again just every other day but again spots started appearing so now I’ve stopped completely. Very annoying as it is very expensive and I had over 3/4 of the bottle left

Best Kiehls product I have used

This is by far the best Kiehls product I have used. I have used their face cream for many years but only tried this recently and regret replacing it with other less effective serums. I really like the vitamin C in the product and noticed an improvement in brightness as well as reduction in a small dark patch I have under one eye.

Best Use: Treat Pigmentation / Dark Spots, Reduce Dullness, Minimise Fine Lines & Wrinkles, Anti-Aging

Vitamin C

My skin type is dry. The consistency of the product is quite dry, it doesn't spread very far. When applied, my skin didn't look glowy it looked quite matte and dry. I like that the product has a high percentage of vitamin c. I haven't used it for long enough to notice any line reducing qualities. It hasn't irritated my skin.

Best Use: Minimise Fine Lines & Wrinkles, Anti-Aging
