The KTP - potassium-titanyl-phosphate - laser is a vascular laser. It specifically targets the iron-rich protein running through your blood vessels. KTP lasers operate at 532 nm, making it one of the shortest wavelength lasers used in cosmetic dermatology.
What It's Good For
KTP lasers can treat vascular lesions appearing at the surface of your skin, like broken capillaries, for example. Blood vessels that are between one and three millimeters in diameter tend to respond best to KPT treatment.
Who it works for: The ideal candidate for treatment with the KTP laser has a fair to medium complexion.
Recommended age range: KTP lasers can be used on people of all ages.
When will I see results?: Removing a vascular lesion with a KTP laser typically takes approximately three months total. After treating a red skin mark, it may darken before fading.
How long it lasts: Small blood vessels can be removed permanently with the KTP laser, though treatment can't prevent new vascular lesions from appearing with time.
Key benefits of KTP lasers: The KTP is as effective as a pulsed dyed laser when it comes to treating facial telangiectasia. The spot size and pulse width is adjustable. A 1 mm blood vessel is treated with a smaller spot sizes and shorter pulses, while larger vessels are treated with larger spot sizes and longer pulses.
Licensed uses: There are many KTP devices currently available, each with their own FDA clearances. The Gemini, for example, is cleared for vascular lesions like telangiectasia, , cherry and spider angiomas, and several other common issues pertaining to blood vessels.
