Hi, I am using the attached Kozicare skin whitening soap which contains Kozic acid, Gluthione, Arbutin,
Vitamin C & E. I found this soap very moisturised & great to use. Is it safe to use this soap? Will it lighten the skin as claimed by the soap? Some people on YouTube claim that this soap temporary lightens the skin then again the skin is back to normal? Are there better soaps that this one? Is this soap good for sensitive skin? Also is the Kozicare cream good to lighten skin tone & dark patches?
