Acne is irritating not only when it is active, but even after it heals. This is because it leaves behind unpleasant scars and pigmentation. Laser therapy is the best known way of dealing with these scars and pigmentation issues. It is a misconception that laser treatment is a new form of skin therapy. Laser is being used to treat pigmentation scars since 1964, however, the procedures have evolved significantly and become much more improved and effective.
How does laser therapy work?
Lasers direct intense amounts of monochromatic light at precise points on the skin. This light is emitted in short pulses. When this light hits the skin it heats the hemoglobin cells. The precision with which lasers direct this light ensures that surrounding cells are not affected.
By changing the amount of light, lasers can be used to address cells at varying depths of the skin. In the case of scars, they can destroy the excessive melanin deposits causing a scar. It can also boost collagen production.
In most cases, lasers used to treat skin issues are carbon dioxide or argon lasers. These are known as CW lasers. Laser therapy may be short pulsed or long pulsed. The difference between the two lies in the rest period between emitting bursts of light. The type of laser therapy used depends largely on the degree of scarring or hyperpigmentation.
