Ruby Laser — Q-Switched 694nm
Q-switched Ruby laser at 694nm — gold-standard for tattoo removal, lentigines, and stubborn pigmented lesions on Asian skin.

Ruby Laser delivers nanosecond pulses at the 694nm wavelength — the most selective wavelength for melanin absorption among the Q-switched lasers in our menu (Ruby vs Pico-Alex vs Nd:YAG). Used primarily for: amateur and professional tattoo removal (especially blue-black inks), solar lentigines (sun spots), café-au-lait macules, and post-inflammatory hyperpigmentation that hasn't responded to topical regimens.
The shallow tissue penetration of 694nm means lower risk of post-inflammatory hyperpigmentation on Type IV–V Asian skin compared to longer-wavelength lasers — which is why our patient base for Ruby Laser is heavily Asian-skin-typed.
Where it comes from, what's inside, who certifies it.
Energy-based treatment — no injected or topical substance enters the body. Halal-compatible by default (no ingredient question).
