What is the principle of ice point freckle removal

Freezing point freckle removal is a cosmetic treatment method that uses the principle of selective photothermal action to decompose melanin and reduces skin damage through low-temperature cooling technology. This technology mainly uses specific wavelength lasers to precisely act on pigment particles, combined with an epidermal cooling system to protect the skin. It has the characteristics of high precision and short recovery period. The core mechanism of

ice spot removal is laser selective photothermal decomposition. When a specific wavelength of laser penetrates the epidermis, it is selectively absorbed by melanin and converted into heat energy, causing pigment particles to break into tiny fragments. These fragments are subsequently engulfed and metabolized by human macrophages, and excreted from the body through lymphatic circulation. The intelligent cooling system equipped during the treatment process can monitor the skin temperature in real time, maintain the epidermal layer within a safe threshold, and avoid redness, swelling, or burns caused by thermal damage. The instrument usually adopts a dual pulse mode, with the first pulse preheating the target tissue and the second pulse enhancing the destructive effect. This staged energy release can improve treatment efficiency. The low-temperature protection mechanism of

freezing point freckle removal is significantly different from traditional lasers. Traditional freckle removal can directly act on the epidermis, which can easily lead to scab formation and blackening. The freezing point technology uses a dynamic cooling device to continuously cool the surface temperature in three stages before, during, and after laser emission, ensuring that the surface temperature is always controlled within an appropriate range. When the cooling head comes into contact with the skin, it forms a thermal buffer layer, which not only protects the integrity of the stratum corneum but also allows sufficient energy to reach the dermis layer. Some devices also integrate sapphire light guiding crystals to ensure uniform distribution of light spots and reduce energy fluctuations that can irritate the skin. During treatment, the pulse width and energy density can be adjusted according to the depth of the spots, allowing for targeted treatment of epidermal and dermal spots.

After receiving freezing point freckle removal, it is necessary to strengthen sun protection care and use physical sunscreen to avoid UV stimulation. It is recommended that the treatment interval should not be less than four weeks, during which the medical repair facial mask should be used to promote the recovery of skin barrier. Patients with scar constitution or photosensitive dermatitis should choose carefully, and pregnant women should not undergo such treatment. Mild burning sensation after surgery is a normal phenomenon, and if there is persistent redness and swelling, timely follow-up is necessary. Daily supplementation of vitamin C and vitamin E can help inhibit melanin regeneration, but it is important to note that photoelectric treatments should not be performed simultaneously with other exfoliative therapies.
