Great! This product was initially given to me as a sample by my esthetician. After using it for a few weeks I noticed that it was effectively lightening the dark spots on my skin. Impressed by its results I decided to purchase a full bottle. I have tried numerous skin brightening products in the past to address my melasma and dark spots caused by acne and this one has proven to be the most effective so far.

I have been loving all of the iS products I've tried but this one is the best. I saw some improvement in my skin when using the Cleansing Complex & GenXC in the morning and Active Serum at night but it wasn't until I started alternating between the Brightening Serum/Hydracool serum combo at night that I saw amazing results! I have fair skin that gets oily throughout the day and I struggle with hormonal acne. This serum has worked wonders in keeping my skin clear smooth and minimizing pores and acne scars. It didn't cause any dryness or redness either. I noticed a difference within the first week! I highly recommend it and will definitely buy it again.

Excellent and gentle
Ideal for daily use to enhance and balance skin tone

This is the best skin brightener ever and you will start seeing results within just 2 weeks.

I have found a new essential for my daily routine! This product is absolutely amazing! I have been struggling with melasma above my lip for years but after using this product for just 6 weeks I have seen significant improvement. Initially I was skeptical about the results but now I am overjoyed and plan to continue using it for a bit longer. It does have a slight tingling sensation which might not be for everyone but personally I adore it :)
