赤蘚酮糖是一種天然酮糖。 是一種經(jīng)非致病菌發(fā)酵的水溶性的高純度的免曬型美黑產(chǎn)品。它與表皮角質(zhì)層中角蛋白的游離的氨基發(fā)生反應(yīng)，以達(dá)到染色效果，類似于美德拉反應(yīng)。

此機(jī)制類似于天然日光曬黑動(dòng)力學(xué)，同時(shí)又能避免日曬，保護(hù)嬌嫩肌膚免受紫外線傷害。一般和二羥基丙酮DHA配合使用.使DHA顏色加深,分部更為均勻.用量:1%-3%40℃以下配水。

Function: Erythrulose is a natural ketose. It is a water-soluble, high-purity, sun free tanning product fermented by non pathogenic bacteria. It reacts with the free amino group of Keratin in the epidermal Stratum corneum to achieve the dyeing effect, similar to the Medela reaction. This mechanism is similar to the natural sun tanning kinetics, while also avoiding sun exposure and protecting delicate skin from UV damage. Generally used in combination with dihydroxyacetone DHA to darken the color of DHA and make it more evenly distributed. Dosage: 1% -3% Water below 40 ℃.
