Laser Treatment for Pimples and Pimple Scars


Acne scars are a dreadful disease. It nags the patient’s skin, and when it gets over, it leaves scars behind. Scars from acne are like a double punishment. First, you need to deal with pimples, and now you have scar marks as a reminder. Laser treatment for acne scars is one of the most searched online content in relation to beauty. It is considered just a beam of light to make the acne disappear. Learn more about the laser treatment for pimples and pimple scars.

How Does Laser Treatment Work for Pimples?

The laser treatment works by heating up the hemoglobin inside the blood capillaries and removes the scars from the skin.

Firstly, the heat from the laser works by removing the top layer of the skin where the scar is present. As the top layer of the scar breaks off, the skin will appear smooth, and the appearance of the scar is less noticeable. As the scar tissue breaks off, the heat and light from the laser allow new and healthy skin cells to grow. By the heat of the laser, the blood flow is drawn to the area, and the inflammation is reduced. Hence this makes the acne scar look less raised by giving them a smaller appearance. It also helps in the healing of the skin.

How To Get Prepared Before Getting the Laser Treatment?

It will help if you make some changes in your lifestyle before getting the laser treatment done.

What Are the Different Types of Lasers Used In the Treatment for Pimples and Pimple Scars?

Phototherapy, which includes both UVA, UVB, and blue-red light, is known to have beneficial effects on acne or pimples. Some of the lasers have also been found to be effective in reducing active acne. Active acne means acne which is red or has pus. The laser is also useful in improving acne scars. The use of carbon dioxide lasers and Er: YAG lasers (erbium-doped yttrium aluminum garnet) for treating acne scars are well known. Other lasers which are found to be useful are flashlamp-pumped pulsed dye laser and diode laser.

CO2 Laser 10600 nm and Er: YAG Laser:

These are resurfacing lasers, and they induce rejuvenating skin changes through open epidermal and dermal wounding on ablating the skin surface.

Flashlamp-Pumped Pulsed Dye Laser 585 nm:

PDL lasers are found to be useful in inflammatory acne lesions. In this, laser beam rapidly moves across the face for 15 minutes, it causes non-lethal healing by its selective action on the superficial vasculature in the upper dermis, and this is believed to act on inflammatory lesions of acne vulgaris and acne rosacea. The nonablative lower fluence also induces stimulation of cutaneous procollagen through altered local cellular metabolism and results in improvement of acne scars.

DIODE 1450 nm:

This diode is absorbed by tissue water, which is its principle chromophore. It penetrates to the depth of papillary dermis, where on its absorption, induces thermal injury up to 400 to 500 micrometer in the form of dermal healing. This thermal profile matches the anatomic depth of sebaceous glands, and this leads to thermal injury, resulting in a change in their activity and function. This laser is useful in treating active inflammatory lesions and sebaceous hyperplasia. Dermal heating also induces collagen remodeling, thus bringing about clinical improvement in acne scars.

Both the flash-lamp and diode laser systems have incorporated an epidermal cooling system to avoid and reduce the side effects and complications, such as pigmentary changes and superficial scarring.
