Acne & Inflammation
Vascular Lesions
560–590 nm IPL – rosacea and redness; 1064 nm Nd:YAG – deeper vessels; Pulsed Dye Laser – superficial vessels; RF – adjunct coagulation.
Pigmentation
515–590 nm IPL – sun damage; 532 nm QS Nd:YAG – epidermal pigment; 755/694 nm – deeper pigment; 1064 nm Nd:YAG – safer for darker skin.
Tattoo Removal
532 nm – reds; 694/755 nm – blues/greens; 1064 nm – blacks. Uses Q-switched or picosecond lasers.
Hair Removal
755 nm Alexandrite – lighter skin; 810 nm Diode – versatile; 1064 nm Nd:YAG – darker skin.
Resurfacing & Texture
1320–1927 nm non-ablative – collagen; 2940 nm Er:YAG – superficial; 10,600 nm CO2 – deep resurfacing.
Skin Tightening
Radiofrequency and Ultrasound for collagen stimulation and tightening.
Benign Lesions
RF – skin tags, milia; 1064 nm Nd:YAG – cherry angiomas. Moles should not be treated with lasers.
Specialty Treatments
Toe fungus: 1064 nm Nd:YAG, 940 nm diode. Stretch marks: CO2 fractional, non-ablative lasers.
