Acne breakout!

I began using the product and within a week had really bad spots unlike anything I had since teenage acne - I didn’t connect it to the product at first as I’d also started using Kiel’s microcode retinol and thought it might be -purging so stoped the retinol - a week later my skin is much worse with really angry and sore breakouts and spots everywhere. I spoke to the assistant in Kiehls and she explained given the vit C is an ‘active’ product it’s likely the cause and to stop using it. My skin is so bad and sore I’ve actually booked an appointment with a dermatologist as it’s really impacting my confidence. Super annoying to have spent so much money on a product that I’ve been advised to stop using. I wish I’d looked at reviews prior to purchase.

Great Product

I have been using this product for several months and it is one of my favourite products. It leaves a warm feeling after applying and feels like it is bringing a deep penetration into the skin

Wow. What a product

I received this product as a sample along with the day cream I had ordered. I shall be purchasing it. The warm feeling it gives on application to the face is so smoothing.

Good product

[This review was collected as part of a promotion.] Grainy consistency but as you rub on the skin, it disappears. Stung me at the beginning but got used to it. Have to use more to see benefits.
