[Health Week] Lasers in Acne Treatment
Inhibiting sebaceous gland activity is crucial in acne treatment. In the past, photodynamic therapy (PDT) was the leading treatment. PDT involves applying a photosensitizing agent that responds to the 410nm visible light spectrum and then irradiating it with light to activate the drug. This treatment destroys sebaceous glands and improves acne.

However, Gold PPT has recently gained more attention than PDT because it is much more potent and effective. Gold PPT involves absorbing a drug made of gold nanoparticles into pores via ultrasound. The gold particles then react with the laser, increasing the temperature within the pores and destroying the sebaceous glands. This treatment requires a long-pulse laser with a 1064nm wavelength.

Another treatment that destroys sebaceous glands is sebaceous acupuncture. While acupuncture isn't actually a laser treatment in the strictest sense, these days, all treatments utilizing high-frequency and ultrasound equipment are collectively referred to as laser therapy, so I'll include it in this explanation.

Acupuncture involves extracting acne, then inserting an insulated needle into the pore and applying high-frequency waves to destroy the sebaceous glands. The insulated tip of the needle prevents damage to the outer skin, effectively targeting only the sebaceous glands. This treatment is particularly effective for treating recurrent pustular acne.

Next, laser treatment is used to improve acne scars. Even when the inflammation subsides, red marks remain. While these marks usually improve over time, some persist and become discolored. Lasers are also used to treat these pigmented scars. Using a long-pulse laser with a wavelength of 1064 nm, it delivers thermal energy deep into the skin, stimulating collagen production to treat redness and rosacea.
