How are depressed scars treated?

Depressed scars refer to scars caused by defects in the subcutaneous tissue of the dermis layer of the skin, such as common acne surgery, traumatic infection, etc. These are the causes of depressed scars, so the treatment can be microcrystalline scar removal, mechanical stimulation, or laser grinding.

1. Microcrystalline scar removal

It is to spray natural crystals in a vacuum at high speed onto the uneven surface of skin scars, thereby stimulating skin growth and promoting the production of collagen and elastic fibers. The advantage is that the force on the treatment surface is uniform and gentle; the disadvantage is that it has poor targeting and requires more treatments. Suitable for superficial scars with single shape.

2. Grinding

It uses an electric grinding head to grind away scars. The advantages are strong targeting, fast speed and less number of treatments; the disadvantages are

Bleeding spots and micro-injuries require bandaging. Suitable for large areas of scars and pigmentation.

3. Mechanical stimulation

It uses special instruments to stimulate the skin and promote skin growth. The advantage is that the skin damage is small; the disadvantage is

Manual operation, slow. Suitable for single superficial scars.

4. Laser grinding

This method does not cause bleeding after treatment and recovery is relatively faster. At present, high-energy pulsed CO2 lasers and pulsed erbium lasers are commonly used for laser grinding.

5.UHF

The damaged tissue is vaporized by ultra-high heat. Advantages: The surgical field is clear and the treatment stratification effect is good; Disadvantages: There is a period of scabbing and shedding of the wound after treatment, during which time attention should be paid to the protection of the wound. Suitable for all kinds of scars, mainly hypertrophic scars.
