Acne has now become a multi-morbidity and with the prolongation of the disease, multiple damages, cysts, nodules, and scarring can occur, which requires a treatment for acne that strives for early intervention, good treatment results, low side effects, and as much holistic and comprehensive treatment as possible to enhance the beauty of the facial skin. Medical lasers have become a new technology for the treatment of acne and are gradually showing their unique characteristics of rapid, efficient, low side effects and overall facial skin enhancement. The Q 1064nm pulsed laser, which can penetrate the epidermis, has a selective absorption effect on the melanin in the epidermis and subepidermis, which can cause targeted destruction of melanin in melanocytes, and at the same time, it also has an activating effect on the collagen in the dermis, promoting its remodeling, integration and restoring a good framework structure of the dermis. Using its above-mentioned characteristics, nano-scale toner particles are applied to the epidermis and the toner is removed by laser. There is light heat generated during the removal process, which does not act directly on the skin, with high safety and very little adverse reactions. The principle of acne treatment is as follows: 1. The nano-scale toner particles can penetrate into the hair follicle through the entrance of the follicle, and due to the high adsorption characteristics of the toner, it can adsorb a large number of accumulated sebaceous glands and secretions. 2.While the laser blasts the toner, it generates instantaneous light heat, but less than the epidermal thermochromic threshold time, which can quickly survive to kill the acne propionic acid bacillus, providing fast and efficient thorough removal of the etiology of acne treatment. 3, At the same time, it stimulates collagen regeneration and repairs the dermal framework of acne lesions, providing a good repair of acne scarring and early damage. 4.The carbon powder on the epidermis can also lightly necrotize the keratinocytes while blasting, accelerating epidermal turnover and regeneration, and reducing hyperkeratosis of the hair follicles in acne. 5. At the same time as laser treatment, it can also lighten melanin spots and acne marks. 6. The treatment process is short, safe, painless, and non-stimulating, with quick post-operative recovery, no downtime, simple post-operative care, and both medicated cosmetics and ordinary cosmetics can be used. Comprehensive above laser + mesotherapy principles, it can be seen that this treatment method should be very ideal for acne, and the treatment effect in the clinic is very satisfactory. Generally, acne below moderate level can achieve relief and recovery after 2-3 treatments.
