iS CLINICAL C Eye Serum Advance+, 0.5 Fl Oz

I've tried so many eye creams and serums from different brands over the years. This is the only one that I see actual results with. It leaves my under eyes brightened and smooth and has reduced my undereye bumpiness. It also works very fast. Definitely expensive but to me it's worth it to have something that's actually making a difference

I can tell the difference in my skin around my eyes. Firmer and a visible decrease in lines

I really wanted to love this product but unfortunately it gave me a bad allergic reaction every time I used it. I tried using it on its own and then with a moisturizer but it would break me out no matter what I did. It would take at least 4-5 days for my under eye area to go back to normal. The return window closed and now I have a product I cannot use. I wish they would give a longer period to test it out one month is not enough if I’m spending more time trying to relieve my allergic reaction each time I use the product.

Haven’t seen brightening effect for me, but it’s an ok serum

My under eye area is naturally prone to puffiness and this product has really been great. I can even put it on at night (most eye products just make my eyes more puffy overnight) and wake up looking more rested.
