When used as a hair removal method, both lasers and intense pulsed light (IPL) use light to heat hair follicles and prevent regrowth. While it may sound similar, everyone uses different techniques. The main difference is the light source used.
To help you decide which hair removal method is right for you, dermatologists Lucy Xu and Candela Medical’s Dr Salinda Johnston, founders of the London Excellence Laser and Skin Clinic, explain what you need to know about two treatments.
Laser Hair Removal Explained
Xu explains, “Laser treatments affect hair that is in the active anagen phase (growth phase). The laser beam consists of precisely controlled pulses of energy that are absorbed by the melanin, or pigment, in the hair to reach the active hair follicles under the skin.” Essence On, the energy heats the hair – all the way to the base of the hair root – and destroys it safely without damaging surrounding tissue or skin. “This process is also known as photothermal destruction,” she added.
”Most people need six to eight sessions, after which the hair is visibly reduced or permanently removed and the skin appears smooth and even.”
IPL for hair removal explained
Xu clarified that the intense pulsed light technology, also known as the intense pulsed light technology 3354, is not actually a laser treatment. “Compared to laser hair removal, it uses multiple wavelengths of broad-spectrum light. That means it has a more concentrated energy around the hair and skin.” So, IPL uses multi-spectral light, while lasers use single-spectrum light. “This means that the IPL energy is spread out and much weaker. The laser has dense light, and all the energy is concentrated in this single light.”
Speaking of IPL, Xu explained the science. “Spectral light is measured in wavelengths (nanometers). For example, a wavelength of 755 nanometers means that this spectral light can penetrate to a depth of 755 nanometers under the skin. Light with a wavelength of 755 nm is most attractive to melanin, so it is best for hair removal. 52 Nano means that light can reach 532 nanometers under the skin.” Red blood cells in the blood absorb this light most, so IPL is very effective in treating the appearance of ruptured capillaries on the surface.
Dr. Johnson reiterated that, unlike laser treatment of specific wavelengths, IPL works by emitting light at scattered wavelengths. “Various cut-off filters are commonly used to selectively filter out unwanted wavelengths of specific structures and chromophores. This could be melanin in the form of pigmented lesions on hair or skin, or oxyhemoglobin in blood vessels, which are characterized by Broken capillaries. In more severe cases, it could be rosacea,” she explained. This makes IPL a gentle and effective treatment for people with rosacea, facial flushing and hair loss. When used exclusively for hair removal, IPL typically requires six to eight treatments to completely remove hair from a specific area. “However, it depends on people’s skin tone, hair color and hair thickness,” Xu added.
Which is better for hair removal, ipl laser hair removal or laser?
Xu said: “Normally, IPL technology requires more treatment and may produce less effective hair loss results. The new laser technology we use clinically is more advanced, more effective, and less painful than IPL technology (because they Equipped with an integrated cooling system). Furthermore, this means that our machine can treat a wider range of skin and hair types than IPL.” It is for this reason that they use IPL for larger purposes such as skin regeneration (as above mentioned).
While the skincare expert believes that if people just want to remove unwanted hair, a real laser is the best option, she did say that “laser and IPL are effective when delivered by a qualified laser practitioner”. Both experts agree that it’s important to discuss your specific concerns with a esthetician and consider your skin type so they can advise you on the best course of action.
What is the best laser hair removal?
”We provide the best results with the most advanced laser hairdressing machines; Candela and Cynosure are two of the leading and most trusted laser technology suppliers in the laser hairdressing industry,” Xu said. “These techniques combine an emerald laser, which is ideal for light skin types, and Nd:YAG, which is ideal for darker skin types.”
All hair colors and skin types on Fitzpatrick’s skin scales are safe to handle depending on the device (according to science, light needs to be attracted to melanin). “Therefore, everyone is advised to do a patch test ahead of time and consult with a therapist to determine the best approach for them.”
What does laser hair removal require?
Dr Johnson explained: “When we use Candela’s Nordlys device on clients, they typically need six to eight treatments. Patients need to come every four to eight weeks (depending on the area of the body), and only developing hair is The damage will be successful. Between treatments, the patient can shave, which can cause the damaged follicles to fall out.” She stressed that it is important not to expose the area to any sunlight and use SPF 30 as part of your daily routine or higher sunscreen to protect the area.
