Skin problems caused by uneven pigmentation are common not only in sunny seasons but also during pregnancy and breast feeding and in case of mature skin. This product is an excellent choice for counteracting hyper-pigmentation. The bearberry content of Brightening Serum controls the production of melanin, preventing the appearance of further spots. The other plants contained in the serum – horseraddish, parsley, lemon and stonecrop – have a brightening effect. By enhancing one another’s effect, they reduce both types of hyper-pigmentation: age spots and sun spots. The mixture of the various plants regenerates and supplies vitamins to the skin. The serum is able to exert its effect more efficiently if the skin is pre-prepared with Sea Sand & Willow Peeling and is combined with the Stonecrop product line or Brightening Cream. It is an important supplement to brightening oxygen treatment. Regular usage will produce a long-lasting effect.
