I have finished my first bottle of ivory caps and all I can say is how amazed I am with the results. Not only my skin is glowing,I feel like I have more energy everyday. I noticed on the first week that I took this was how my hands were lightening then the rest of my body followed. Im not sure how many shade lighter I am but I'm really convinced I have found the real Glutathione that really delivers good results. I have tried many reduced form of glutathione and only this and Jarrows formula are my top favorites. For a super vain woman,this is a must have.
