When used as hair removal methods, both lasers and intense pulsed light (IPL) uses light to heat hair follicles and prevent them from growing back. While it sounds similar, the technology used by each one really isn’t, and the key difference is the light source used.
Explanation of laser hair removal
Xu explains that “laser treatment affects hair in the active growth phase (anagen stage). The laser beam is made up of precisely controlled pulses of energy that are absorbed by the melanin or pigment in the hair and reach the active hair follicles under the skin. “Essentially, the energy heats the hair, all the thanks to rock bottom. from the root, destroying it safely without damaging the surrounding tissue or skin. “This process is also called photothermal destruction,” he adds.
Explanation of IPL for hair removal
IPL technology, also known as intense pulsed light technology, is not actually IPL Treatment, Xu clarifies.“Unlike laser hair removal, it uses a broad spectrum of sunshine with multiple wavelengths. This means that it has more defocused energy around the hair and skin area. “So IPL uses multi-spectrum lights while laser uses single-spectrum light,” which means the energy from IPL is scattered and it is much weaker. The laser has a densified light and all the energy is concentrated in this single light. “
When it comes to IPL, Xu explains the science.“Spectrum lights are measured as wavelength (nm), for instance, a wavelength of 755nm means this spectrum light can penetrate 755nm deep under the skin. 755nm wavelength light is better attracted to melanin, so it is best used for hair removal. 532nm means that the light can reach up to 532nm under the skin. “Red blood cells in the blood have the highest absorption towards this light, so IPL is very effective in treating the appearance of superficial broken capillaries. When used specifically for hair removal, IPL generally requires six to eight treatments to see complete hair removal in one area. “However, this relies on the person’s complexion, hair color, and also the thickness of the hair,” Xu adds.
Which is best for hair removal, IPL or laser?
Xu says: “Typically, IPL technology would require more treatments and should end in less effective hair reduction. The new laser technologies we work with within the clinic are more advanced and effective than IPL counterparts with less hassle (as they are equipped with integrated cooling systems). Also, it means that our machines can treat a wider range of skin and hair types than an IPL would. “It is for that reason that they use IPL for more important purposes, like skin rejuvenation (as mentioned above. ).
While the skincare specialist believes that if people just want to get rid of excess hair then truth laser is that the best choice, she does say that “both laser and IPL are effective when performed by a qualified laser professional. ”. Both experts agree that it is important to discuss your specific concerns with your cosmetic doctor and take your skin type into account so that they can advise you on the best course of action. It is up to the team if all hair colors and skin types on the Fitzpatrick skin scale can be safely treated (according to science, light must be attracted to melanin). “Therefore, it is recommended that everyone get a patch test and consult with their therapist beforehand to identify what is best for them.”
