Correct understanding of laser freckle removal

Laser freckle removal is not “one shot”

Some doctors often meet such beauty seekers: “doctor, can the spots on my face disappear all at once?” This has to start with the principle of laser freckle removal.

Principle of laser speckle removal:

The laser instrument generates a high-strength beam, which can instantly reach the deep layer through the skin epidermis, so that the pigment particles inside the skin can be instantly crushed, and the crushed pigment particles will be swallowed by human macrophages and slowly “transported” away. Lasers of different wavelengths can pass through the epidermis and dermis, reach the diseased pigment tissue, and only selectively absorb the pigment particles. Therefore, the epidermis of the skin is rarely damaged or even not damaged, there is no obvious damage to the texture of the skin, and no scar will be left on the skin.

Generally speaking, the time for the elimination of pigment particles after laser freckle removal is 3 ~ 6 months. Due to the size, type, depth and color of pigment particles in different pigmented diseases, as well as individual differences in skin color, metabolic capacity and age, the time and degree of elimination of pigment particles after laser treatment are also different. Generally, in clinical practice, laser freckle removal requires 1 ~ 5 times of treatment, with an interval of about 1 ~ 2 months.

Freckle removal times are related to two factors

First, the beauty seekers’ own conditions, different skin types, different types of spots, and different times of laser treatment. People with large spots and dark colors need more treatment. Second, the choice of laser instruments. At present, there are many laser equipment used for freckle removal, and the treatment times of different laser equipment will be different.

At present, Q-switched laser is a powerful weapon for battle spots, which can treat different pigmented spots on the true and epidermal layers, such as chloasma, freckles, sunburn, age spots, etc. It combines the dual advantages of traditional laser focused symptomatic treatment and soft and tender skin with compound color light. When acting on the skin, the energy is soft and comfortable, and will not cause damage and bleeding of the epidermis; At the same time, freckle removal can also effectively eliminate skin problems such as dark yellow, dry and red blood.

Different types of speckle removal with different wavelengths

The spot types of laser treatment with different wavelengths are also different. For example, Q-switched laser is not easy to be absorbed by water and hemoglobin and penetrates deep into the tissue. Such dark blue and black tattoos and dermal pigmented lesions as OTA nevus, coffee nevus, freckles, age spots, traumatic pigmentation, dark tattoos such as black, blue and blue, tattooed eyebrows, tattooed eyeliner and tattooed lips can be removed with this laser.

However, melanocytes have a strong absorption of 532nm laser, and have a good effect on the superficial red and Tan pigmented lesions, freckles, coffee spots, naevus erythematosus, telangiectasia, rosacea, etc.

In contrast, the 694nm laser has a high absorption rate of melanin, which is especially suitable for various benign pigmented diseases, including pigmented lesions, dark black tattoos, beauty tattoos, traumatic dust tattoos, etc.
