Does the subject want to ask, "Is there lead and mercury in the spot removing solution?" No, freckle removal technology mainly introduces and decomposes melanin under the skin, and achieves the effect of timely and rapid freckle removal through metabolic desalination and metabolism. Through the transdermal penetration enhancement technology of nano-crystallites, the effect of whitening and freckle removal is achieved, and it will not cause any damage to the skin barrier, which is different from the traditional freckle removal technology and completely replaces lead and mercury products. Therefore, the solution does not contain lead and mercury.
