The skin toning laser is an extension of the traditional 1064-nm neodymium-doped (Nd):YAG spot removal laser. It mainly utilizes the selective photothermal and photoacoustic advantages of laser energy, and by the proper adjustment of laser energy and change in probe irradiation area, it enables the specific 1064-nm wavelength of superior skin penetrability to homogenously emit laser photothermal energy at the dermal layer, which accelerates epidermal keratin metabolism, stimulates collagen reproduction, promotes melanin metabolism, and elevates skin immunity and hydration function, thus achieving the purpose of shrinking pores, refining skin, smoothing fine lines, and lightening black spots. This skin toning laser is used in noninvasive laser surgery and does not directly damage the skin epidermis but gradually solves and eliminates the original problems from the deep layer. Despite leaving no visible wound or scar on the patient’s face, it usually requires several courses to achieve distinct and stable skin improvement. In terms of treatment technique and objective, the skin toning laser is available in the following two treatment models:
Carbon powder laser
This is commonly called dark porcelain doll laser and is an advanced application model of the toning laser. Regarding the procedures, a thin layer of medical nano carbon dust (also called carbon mask or powder) is applied to the patient’s face before laser emission, and then, the minute carbon molecules penetrate into the pores and deep sebaceous gland layer. Next, 2–4 rounds of laser treatments of different energies are given to knock and excite the carbon melanin infiltrated into the pore periphery, which instantly shrinks pores and collagen, thus rapidly shrinking pores, cleaning acnes, removing aged keratoderma, inhibiting sebaceous secretion, tightening the skin, and accelerating dark spot metabolism.
The carbon dust laser is primarily aimed to improve oily skin, rough skin, and pore obstruction. It is mild and does not require recovery time compared with common tartaric acid skin peel and does not have any risks of darkening. However, the carbon dust laser belongs to a progressive skin rejuvenation treatment, and initially, treated patients should undergo 4–6 sessions, once every 3-4 weeks, to attain stable and obvious improvement. To sustain long-term effects, patients also undergo maintenance treatment once every 2-3 months at the end of treatment, which offers caring and preventive functions. Moreover, concerning complicated skin problems, other cocktail phototherapies may be necessary between or after sessions to obtain complementary and multiplicative results.
Carbon-laser skin rejuvenation remains to be the fastest treatment to refine pores.
