Recaell technology is a new international technology for the treatment of scar and pigmented skin diseases, and has achieved excellent results in the repair of keloid scars, scar pigment changes and superficial wounds all over the body. After spraying this suspension on post-abrasion wounds, not only is the healing time shortened, but the risk of pigmentation changes is also greatly reduced. The Recell technique is still very effective for acne-induced depressed scarring, superficial scarring, post-implant hyperpigmentation, and pigment loss from various causes. The recell technique has significant advantages for these conditions, which are often difficult to treat with dilators and also feel more damaging.
