Eiffel uses bioenzyme permeation techniques, including skin-free, haemorrhaging, pain-free, poison-free, safety-free, professional freckles, brown spots, sun spots, old-age spots, hormonal spots, real-skin stripes, mixed spots, black moles, pox prints, flat flats, sweat tremors, fat particles and laser pigmentation. Eiffel is medically based, therapeutic in nature, different from the beauty of life, and not limited to the face, not just dilution. It is based on therapeutic, in vitro consolidation, the removal of the disease from the body, a radical change in the hysteresian living environment, characterized by the absence of incentives and clean-up, with little rebound or relapse. Eiffel technology is an instant dehydration technique for target cells that can be identified from the bottom of a spot and be removed from normal skin。
