I was bamboozled by the esthetician into purchasing this after my light chemical peel for hyperpigmentation and I am so happy I did! This is my first serum and it is so lightweight. You apply it to your skin and it absorbs so quickly, you feel like you didn't put anything on your skin! The ingredients are hydroquinone, retinol, kojic acid, hyaluronic acid, vitamins e and c, licorice, and glabra root extract. In other words, a skin lightening dynamite. I've only used this for about 3 days, but the lightweight feeling plus the active ingredients makes this $31 US worth it. Will update later on how effective it's been.

UPDATE: After cleansing, this is my 1st topical application. Next, 5 minutes later, I apply Image Clear Cell medicated acne lotion. The bleaching serum keeps the spots away. And, the medicated acne lotion prevents breakouts. I alternate every other day with the acne.org line. I look like I do not have acne. My boyfriend is always touching my face. Let me tell you, I've come a long way in the skin department.
