Problems solved by technology

Although these skin care products added with heavy metals can achieve immediate results, skin irritation, erythema, edema, and a series of systemic symptoms caused by skin absorption into the human body after using excessive heavy metal products, such as neurasthenia, fatigue, Anemia and other symptoms

The main defect of most whitening and freckle skin care products is that the effect is slow and inaccurate, and it is easy to cause skin problems such as allergies

On the other hand, due to the obstruction of the stratum corneum of the skin, skin care products that are only applied on the skin surface are difficult to be truly absorbed, and the cosmetic effect is also greatly reduced.
