What are the methods of laser acne removal? How long does it take to recover from laser acne removal?

It is a headache to leave acne pits after acne disappears. Acne pits are difficult to eliminate and can only be effectively eliminated through cosmetic surgery. Laser acne pit removal is a cosmetic surgery project recommended by many people.

Fractional laser and pixel laser are the same thing, both are fractional laser, which is a technology that disperses laser images into "dots" for output. Now it is often used as an abbreviation of "carbon dioxide fractional laser".

Ablative/non-ablative Ablative laser will generate high temperature instantly, vaporizing the epidermis and part of the dermis of the irradiated area, just like "peeling off a layer of skin", and then the skin here will grow again. Non-ablative does not have the step of "peeling off the skin", there is no visible trauma, and the skin can be repaired under relatively mild stimulation. In between the two is micro-exfoliation. In general, the treatment effect of ablative fractional treatment is better than that of non-ablative, especially on depressed scars (acne pits). However, the recovery period of ablative fractional treatment is longer, and there is a risk of pigmentation (that is, black and white patches on the face). Everyone can choose what they need according to their own situation.

Ablative fractional laser: Lumenis CO2, Syneron CO2RE Cool, American Profile laser

Non-ablative fractional laser: Lumenis M22, Cynosure Palomar, and Sellas from Korea

Ultra-pulsed CO2 laser The wavelength of CO2 fractional laser is 10600nm, which is an ablative laser. Compared with traditional CO2 fractional laser, ultra-pulsed CO2 laser can quickly make the laser energy reach the peak, thus reducing the damage to the surrounding skin. However, ultra-pulsed CO2 fractional laser is basically standard in the current CO2 fractional machine.

Fraxel laser Fraxel or Fraxel laser, originally referred to a machine called Fraxel from a certain American manufacturer. Perhaps because it is an earlier and more famous non-ablative fractional laser machine, many merchants/consumers refer to Fraxel as equivalent to non-ablative fractional laser. In other words, sometimes when someone says that a project is done with Fraxel, the machine actually used is not Fraxel, but other non-ablative fractional machines (there is no distinction between good and bad here).

Laser acne scar removal varies according to the location and size of the scar. Generally, after 3-5 or 8-10 treatments, the acne scars can be greatly improved after 6-12 months, gradually blurring and softening, the redness and swelling are slightly improved, and the comfort level is increased. The specific situations are as follows: 1. For superficial acne scars, non-convex ones, 3-5 treatments have significant effects, and the improvement is obvious in about half a year; 2. Some patients have sunken, convex, or even atrophic scars on their entire face. The treatment methods are different. The sunken type requires drug treatment, and then combined with different equipment treatments, which is more complicated.

Everyone knows that acne pits are caused by infection, inflammation or external force. Due to the lack of timely and appropriate treatment during the acne period, the inflammation of skin cells leads to local necrosis and liquefaction of skin tissue, resulting in defects in subcutaneous tissue and scars. Teenagers call it acne pits. Due to the various types of acne, there are many forms of acne pits. The more severe the inflammatory reaction during the acne attack, the more severe the skin tissue is damaged; the deeper the inflammation, the deeper the skin tissue is damaged, and the more severe the acne pits may be left in the future.

The principle of laser acne removal is mainly:

1. Pulsed light: It can shrink capillaries and reduce scars, but it requires multiple treatments. Pulsed light can also increase collagen in the dermis, making depressions less noticeable and improving enlarged pores, so it is also suitable for skin with both erythema and slight pits.

2. Use German midazolam to treat acne and improve acne scars simultaneously, promote the shedding of old dead skin cells, help skin renewal, and improve pigmentation after acne.

3. Purification treatment: It can clear blackheads and pores to prevent and strengthen acne treatment, so generally speaking, laser acne removal is effective.

There are no side effects to laser acne scar removal, except that there may be a little burning pain on the face during the laser treatment. Under normal circumstances, anesthetics will be used.
