Today, more and more people pursue beauty and have high standards for their appearance. While everyone desires to look their best, how can one achieve greater beauty? Laser cosmetic treatments can help you look more beautiful. So, what is the principle behind laser cosmetic procedures?
Laser Cosmetic Treatment Principle:
Laser beams possess high directionality, density, and coherence. They can be focused onto very small treatment areas, ensuring localized effects without damaging surrounding tissues or skin appendages (hair follicles, sebaceous glands, etc.). Penetration depth is controlled by input power; when properly managed, it prevents local scarring. Different laser types operate on distinct principles.The blue-green light emitted by argon lasers (wavelength 488.8–512.5 nm) is selectively absorbed by red pigments. When absorbed by hemoglobin, the radiant energy converts to heat, which can coagulate blood vessels up to 5 mm in diameter. Carbon dioxide lasers operate on the principle of thermal coagulation induced by radiant energy, vaporizing and carbonizing diseased skin lesions.
Post-Laser Treatment Precautions:
1. Protect delicate skin from sun exposure. Apply sunscreen when outdoors. Avoid aspirin and alcohol. Do not squeeze, press, bump, or rub the treated area.
2. Avoid photosensitive foods and medications during treatment. Individuals with sensitive skin should also avoid foods that may cause allergic reactions.
3. After treatment, enhanced skin absorption and accelerated metabolism require diligent skincare to replenish moisture and nutrients.
4. Some patients should keep the treated area dry and clean post-procedure. Physicians will provide specific instructions.
3. Post-treatment, enhanced skin absorption and accelerated metabolism require diligent skincare to replenish moisture and nutrients.
4. Some patients must maintain wound dryness and cleanliness post-treatment. Physicians will guide you in proper care and follow-up.
5. Each treatment course comprises 1-5 sessions. Depending on individual conditions, some patients may require 2-3 courses.
