a bit sticky

This essence is a bit thick, because I don't like skin care products with thick texture, so I gave it a four-star. This texture may cause acne for oily skin. I have been using this for a week, but I haven't see any effect yet. In terms of effect, it is not as good as another essence of Kiehls (Clearly Corrective™ Dark Spot Solution), the dark spot solution can instantly make your skin more transparent

Somewhat of a Stinger

I have received a sample tube of this serum. It clearly has potent active ingredients, as it stings like billyo when applied! The sting does subside to a tingle quite quickly however. It does seem to soften small lines and skin is smooth after use. I did not enjoy the rather medical aroma though, so the positives and negatives are equally balanced for me.

Best Use: Reduce Dullness, Minimise Fine Lines & Wrinkles, Uneven Skin Texture, Anti-Aging

Radiant Skin

When I first tried this I wasn't sure about it. The velvety texture isn't what I'm used to and has more of a silicon-like feel than a moisturiser. When I worked it into the skin I did experience quite a strong tingling in places, although this has now subsided and I don't notice it on application. I don't really have much in the way of wrinkles yet, although I have started noticing some smile lines. I wouldn't say I've noticed much difference with those but my skin is plump and radiant after applying overnight which I really like. I only use twice a week as I have sensitive skin but I do enjoy the after effects.

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.

very good

I have a 5 ml sample and I can say that I really liked the serum. Someday I will buy a full size. It has a light emulsion texture, but is quickly absorbed and the skin simply shines. after application, a burning sensation is felt for several seconds and people with sensitive skin, I think, will be afraid of this. the burning sensation passes quickly, but the effect remains))

Best Use: Treat Pigmentation / Dark Spots, Uneven Skin Texture
