laser facial for acne or pimples :this is best way of treating severe acne.
Blue Light (Laser-420 mm) Therapy
This IPL laser acts by photodynamic therapy in the treatment of acne vulgaris. propionibacterium acnes (p.acnes) produces the porphyrins during their growth and proliferation in the follicle units. The porphyrins produced during this proliferative phase are protoporphyrin IX and coproporphyrinIII.
These porphyrins have an absorption spectrum that is near the ultraviolet (UV) and visible spectrum of light. The major absorption peak for these porphyrins is at 415 nm, known commonly known as the soret band. Therefore phototherapy devices that utilise either blue light or red light PDT for the treatment of inflammatory acne vulgaris lesions.
The PDT process seen in this reaction involves the photoexcitation of the p. acne porphyrins that after exposure to the appropriate light source.This will then form singlet oxygen within the microorganism itself, resulting in the selective destruction of the bacteria.
