4MSK, a whitening ingredient for pharmaceutical use, can inhibit the generation of melanin and prevent the spots and freckles generated due to sun exposure, and can even adjust the unsmooth keratinization. As highlighted by Shiseido, 4MSK can recover the factors at the damaged site, so that the factors at all levels can play a role in the process of melanin discharge to guide the melanin discharge, and the melanin will not lose the way to leave any more. This ingredient is specially added in the IPSA Whitening Lotion.
