This is a professional strength kojic soap that combines pure kojic acid as the skin whitening agent and papaya fruit extract as the skin exfoliator, which promises a fairer, even toned and brighter looking skin if used daily. We added papaya fruit extract to the ingredients so that it will remove your dead skin cells to reveal the healthier cells underneath the skin. The difference between this kojic soap and the other kojic soaps in the market is the formulation. Not all kojic soaps are the same. Most kojic soaps have very little kojic acid in it and this is why you are not seeing any skin whitening effect. Marie France uses high concentration of kojic acid and papaya fruit extract, both are known for its skin whitening and rejuvenating effect to effectively whiten your skin and makes it look even, fairer, smoother and younger with daily use. The skin whitening process is gradual, it does not happen overnight. It normally takes 8 to 12 weeks before you see the maximum results, however, this really depends on your skin sensitivity. This kojic soap can be used on both face and body. It can remove dark areas or skin blemishes such as: acne or pimple scars, melasma, whiteheads, blackheads, hyper pigmentation, dark elbows, knees, inner thighs, bikini area, butt, knuckles, underarms, old scars, etc. Note: This kojic soap is not for people with sensitive skin.
