Laser acne mark removal is not a surgical procedure, but a less invasive medical treatment technique that can help patients effectively remove acne marks. Acne marks, or pigmentation left after acne heals, are most common on the face, chest and back and other areas rich in sebaceous glands, including red acne marks, black acne marks and so on. The principle of laser acne mark removal is that different wavelengths and energies of lasers act on the deeper layers of the skin to help break down melanin particles and accelerate their metabolism, so as to improve the appearance of acne marks, and it is a commonly used medical aesthetic treatment technology at present, such as tuned Q laser and picosecond laser to help remove black acne marks, and pulsed dye laser to help remove red acne marks, and so on. After laser treatment, attention to strengthen care can help achieve better results in removing acne marks, such as: diet to light diet, avoid spicy and stimulating food, quit smoking and alcohol; laser treatment to avoid water, pay attention to strengthen the sunscreen; to ensure sufficient sleep and good rest, avoid staying up late, appropriate supplement vitamin C and so on. It is important to note that patients are advised to go to a regular medical institution for laser acne mark removal operations to avoid adverse reactions.
