Our skin every day on their own metabolism, resulting from the basal cells gradually reach the skin surface, and then become a cuticle, the skin hyperkeratosis cycle is usually around 28 days, due to the environment, season, UV, rest is not normal and other factors, sometimes cause slow metabolism, so our skin piles up thicker stratum corneum, horny excessive accumulation, it will allow a transparent discussion so that the skin does not feel a sense of, and have lost the flexibility of the original, so fixed and the appropriate exfoliation, dander can be removed, so that the skin is more translucent.

我们的肌肤每天都会自行新陈代谢，由基底层产生的细胞会慢慢的到达肌肤的表面，然后成为角质层，皮肤的角化周期通常约为28天，由于环境、季节、紫外线、作息不正常等因素，有时会使新陈代谢变得缓慢，所以我们的皮肤表面角质层越堆越厚，角质过度的堆积，就会容议让肌肤感觉没有透明感，也失去原本的弹性，所以固定且适当的去角质，可以将皮屑去除，让肌肤更晶莹剔透。
