Interaksi Laser -Jaringan Refleksi Transmisi Penyebaran (Scattering) Re-emisi Absorpsi Absorpsi menghasilkan interaksi photochemical, photo thermal, photomechanical. Senyawa yang mengabsorpsi cahaya ini disebut chromophores. Chromophores yang menyerap panjang gelombang 1064nm (Nd: YAG) adalah melanin, oxyhemoglobin, dan desoxyhemoglobin.

Jerawat Photoselective absorption selektif destruksi pada kelenjar sebacea Thermal efek menstimulasi collagen remodeling For active acne, Fotona’s laser treatment reduces acne inflammation through photoselective absorption and controlled heating effects. Fotona’s high powered Nd:YAG laser safely penetrates the skin to an optimal treatment depth to thermally and selectively destroy overactive sebaceous glands. In addition to its thermal penetration effects, the Nd:YAG acne laser treatment also accelerates the healing process and stimulates collagen remodeling, an important step in the long-term treatment of acne.
