Correct Understanding Of Laser Freckle Removal

Laser freckle removal is not “one shot”

Some doctors often encounter 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 freckle removal:

The laser instrument generates a high-strength beam, which can instantly pass through the epidermis of the skin to the deep layer, 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 with different wavelengths can pass through the epidermis and dermis to 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 there will be no scars on the skin.

Generally speaking, the regression and discharge time 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 individual skin color, metabolic ability and age, the regression and excretion time and degree of pigment particles after laser treatment are also different. Generally, 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 seeker’s own situation, different skin types, different types of spots, different times of laser treatment, and those with large spots and dark colors need more treatment. Second, the choice of laser instruments. At present, there are many laser equipment 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, senile spots and so on. It combines the dual advantages of traditional laser focused symptomatic treatment and compound color light soft and tender skin. 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.

The types of speckle removal vary 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.

Melanocytes have strong absorption of 532nm laser, and have good effects on superficial red and Tan pigmented lesions, freckles, coffee spots, fresh erythema nevus, telangiectasia, rosacea and so on.

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