Yet another laser in Mizu’s range of pigmentation lasers, the ruby laser is a solid-state laser that uses a synthetic ruby crystal rod to emit a wavelength of 694nm to target skin pigmentation.
As one of the few clinics in Singapore to have a ruby laser, Dr YZ Tan has developed specific settings for the ruby laser, combined with components from the pico laser, unique to Mizu for treating specific pigmentation conditions.
Different laser treatments work in distinct ways. Since various types of pigmentation exist in different skin layers, it is essential to use a machine that can reach the affected layer.
The ruby laser, at 694nm wavelength, is used to treat epidermal pigmentation, such as freckles, sun spots, lentigos, and age spots, as well as some dermal pigmentation such as melasma.
Clinical studies suggest that pigmented lesions in Asian skin must be treated with high energy densities, making the ruby laser a suitable treatment. The ruby laser can effectively reduce pigmentation with fewer side effects due to its high absorption rate by melanin and low absorption rate by other skin components.
From the graph, it is evident that at the 694nm wavelength, the ruby laser’s energy is primarily absorbed by melanin and minimally by oxyhemoglobin and water. With hyperpigmentation (darkening of the skin) being a common side effect of lasers, this reduced absorption by oxyhemoglobin and water and high absorption by melanin means that the ruby laser can remove melanin (pigmentation) more effectively with a lower risk of hyperpigmentation.
This is because the ruby laser can operate at a low power setting while still allowing a significant amount of energy to be absorbed by melanin compared to other lasers. This allows the laser energy to be maximised, effectively removing pigmentation with reduced chances of side effects.
The ruby laser is particularly effective at removing deep epidermal pigments that were previously challenging to reduce with other lasers.
The effectiveness of the ruby laser in removing a tattoo depends on the type of ink used. Studies have shown that blue, black, and green tattoos respond well to the ruby laser due to the strong absorption of red laser light.
During the tattoo removal process, the laser selectively targets the ink molecules, which are then absorbed and eliminated by macrophages (immune cells).
At Mizu Aesthetic Clinic, we offer four different types of pigmentation lasers: the Ruby, Pico, Q-Switched and Yellow. Each laser has distinctive features designed to treat various types of pigmentation.
Understanding that each machine has different wavelengths targeting different layers of the skin, our doctors can analyze and identify the most suitable treatment for effectively addressing various pigmentation issues.
