p 61 , IPL เป็น basic emit pulse of broad-spectrum visible and near visible infrared light
different optical filtering technique – restric bands of wavelenght to match specific absorption of – 2 major skin chromophore -> Hb , melanin
pulse duration for IPO ต่าง laserอื่นๆ ที่ , IPL สามารถ adjust within wide range ->ทำให้ IPL สามารถใช้ได้มาก very versatile , highly efficient ในการรักษา vast range of skin codition
IPL เป็น 1st choice – facial rejuvenation Rx of – diffuse redness , telangiectasias , epidermal pigmentation
Fine wrinkle สามารถลดลงโดย IPL , และถ้า combine กับ photodynamic Rx (PDT)~ ปสภ พอๆกับ – fractinal laser
IPL – PDT ถือว่า high-efficacy in acne Rx
IPL – most use for hair removal , ปกส พอๆกับ Alexandrite , diode laser
5.1 Introduction
::: IPL broad-spectrum, 500-1200 nm , other lasers เป็น monochrome
Carbon Dioxide (CO₂) Laser:
- Wavelength: 10,600 nm (far-infrared)
- Application: Skin resurfacing, facial wrinkles, and scar removal, as well as surgical excision of tissue.
Erbium:YAG (Er:YAG) Laser:
- Wavelength: 2,940 nm (infrared)
- Application: Skin resurfacing, fine wrinkles, and treatment of superficial skin lesions. It has less thermal damage compared to the CO₂ laser.
Alexandrite Laser:
- Wavelength: 755 nm (near-infrared)
- Application: Hair removal, treatment of pigmented lesions, and tattoo removal. It is highly effective on lighter skin tones.
Diode Laser:
- Wavelength: Typically 800–810 nm (near-infrared)
- Application: Hair removal, especially for darker hair and lighter skin tones, and vascular treatments.
Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) Laser:
- Wavelength: 1,064 nm (near-infrared)
- Application: Hair removal, vascular treatments, and skin tightening. It is often used for deeper penetration and darker skin tones.
KTP (Potassium Titanyl Phosphate) Laser:
- Wavelength: 532 nm (green light)
- Application: Vascular lesions, acne, and pigmented lesions. This laser is often used in procedures targeting superficial blood vessels.
Ruby Laser:
- Wavelength: 694 nm (red light)
- Application: Pigmented lesions, tattoo removal, and some hair removal treatments, particularly effective on fair skin tones.
Titanium Sapphire Laser (or Alexandrite-Like):
Application: Similar to the Alexandrite laser, used in hair removal and skin rejuvenation.
Wavelength: 750–950 nm
