Which is better to lighten the buttocks, knees and elbows–Diana Stalder Papaya Kojic Soap or Glutathione Soap?
Rating: +0
As you might suspect, the answer really does depend on the individual. We've had many customers try both products for these common problem areas. Roughly 50-60 percent report that the Diana Stalder Glutathione Soap is better for them, while maybe 20 percent prefer the Diana Stalder Papaya Kojic Soap, and the remainder say the results were about the same between the two.
Of course, whichever soap you choose, your results will be greatly improved by combining usage with the Diana Stalder Surely White Whitening Cream, at least on knees and elbows. For buttocks, the Diana Stalder Surely White Body Whitening Lotion is probably a better choice due to the larger surface area.
