  "what": "Laser hair removal uses laser energy absorbed by melanin in the hair to heat the follicle and reduce regrowth, a principle called selective photothermolysis. At Dr Sin Yong's practice on Orchard Road, Singapore, it runs on the R2 Glow platform, a long-pulsed laser carrying 755 nm alexandrite and 1064 nm Nd:YAG, so the wavelength can be matched to skin type area by area. Treatment is staged because follicles respond mainly in the growth phase, every treatment is doctor-supervised, and no duration of effect is promised.",
  "key_facts": [
    "Platform: R2 Glow, a long-pulsed dual-wavelength laser with 755 nm alexandrite and 1064 nm Nd:YAG, with epidermal cooling",
    "Wavelength by skin type: 755 nm is strongly absorbed by melanin and suits Fitzpatrick I to III; 1064 nm is less absorbed by surface melanin, penetrates deeper and suits Fitzpatrick IV to VI",
    "Hair limits: white, grey or very fine hair carries little melanin and responds poorly, whatever the device",
    "Areas: brazilian and bikini, underarms, legs, arms, upper lip and chin, back, chest and beard line; planned together where it makes sense, but set independently",
    "Preparation: shave rather than wax, pluck or epilate, avoid tanning, and declare photosensitising medicines or recent isotretinoin",
    "Risks: redness and small bumps around follicles are common; blistering, burns and darker or lighter patches are uncommon; paradoxical hypertrichosis is rare; eyewear is worn throughout",
    "Doctor-led: settings are determined by Dr Sin Yong after examining the skin and hair in each area, and previous treatment elsewhere is taken into account"
