Triple Whitening Serum Discoloration Removing Treatment - .5oz

I have ordered this from the IYA website several times and it is definitely the most effective skin lightener I have found to date. One of the things that I really like about the formulation is that it does not include any of the ingredients my skin is sensitive to (kojic acid, salicylic acid, etc). I have mild to moderate adult acne and this does a really good job of fading the dark marks and scars left behind. Using a wide-spectrum sun block is a must (like with any skin lightener) or you won't see good results since the sun will just prompt your skin to produce melanin, overriding any progress. Unfortunately, I just can't give it the full five stars since it is really pricy (averages out to around $70/oz). I only use about a nickel sized amount to cover my face and neck, and one bottle just doesn't last long enough, especially since my acne marks stick around like they have no where else to go. It may last a bit longer for those who only use it to spot treat, but like I said, I only use a nickel sized amount any way.
