Concepts and principles of laser spot removal

In this article: Laser spot removal, what is laser spot removal? What is away from laser spot removal? Here is to understand.

What does it mean to get rid of freckles with laser?

Laser freckle removal is a non-invasive laser treatment is a relatively new treatment to improve the appearance of damaged, scarred and damaged skin. A range of different wavelengths of light and devices have been used for non-invasive treatments and have been found to be effective. Freckles are an epidermal pigmentation-increasing skin disorder that is genetically linked and inherited in an autosomal dominant manner.

The pathology is an increase in pigment granules in the basal layer of the epidermis, but not in melanocytes. In the past, the clinical use of freezing, grinding, chemical peeling, cauterization and other methods of treatment, such as mastering the improper easy to produce skin scarring, pigmentation changes and other adverse reactions.

What is the principle of laser freckle removal?

Q open frequency: YAG532nm laser is based on the theory of selective photothermal effect of laser instrument design, irradiation of the skin when the laser energy is mainly absorbed by the melanin bodies in the skin, so that the melanin bodies damage, disintegration, fragmentation, and then phagocytosis of macrophages in the body and discharged out of the body, due to the pulse width of the laser is much less than the melanin bodies preheating time, so the surrounding tissue damage is small, thus achieving no damage to the skin. The laser pulse width is much smaller than the preheating time of the melanocytes, so the damage to the surrounding tissues is small, so as to achieve non-traumatic treatment.

Laser therapy standards should be individualized and must follow biological and physical indicators. In the application of Q-switched frequency doubled Nd: laser treatment of freckles, attention should be paid to the intensity of freckles and the nature of the basal skin color, according to the patient's freckles of the slight characteristics of the adjustment of the laser's physical index, no certainty can be in the inconspicuous place of the trial treatment, and then carry out a wide range of treatment.

In order to reduce the recurrence, avoid sunlight exposure and the use of cosmetics after treatment, and at the same time can use sunscreen and oral vitamin C, E, etc., can also use hydroquinone cream. Freckle pigment disappears, no obvious difference with the surrounding normal skin, no scar formation; obvious effect: freckle pigment reduces, there is a difference with the surrounding normal skin, no scar formation; freckle pigment is basically the same as before treatment, with or without scar formation.
