Different people may receive different answers regarding the difference between IPL and diode laser hair removal techniques. Most people believe that the effectiveness of diode lasers is their main difference, while IPL is not. But where does this come from?
Let's learn about the laser hair removal technology you need to know. It is crucial to understand the difference between diode lasers and intense pulsed light (IPL) before investing in laser hair removal business.
Overview
Both diode lasers and IPL (intense pulsed light) lasers are used for cosmetic treatment, but their mechanisms of action and the types of skin problems they can treat are different.
A diode laser emits light of a single focused wavelength, which can be absorbed by pigments in hair follicles or melanin in the skin, generating heat and damaging hair follicles, thereby inhibiting hair growth or targeting pigment lesions and hyperpigmentation. Diode lasers are more effective for permanent hair removal and removal of pigmentation.
IPL laser emits light of multiple wavelengths, scattering and penetrating the skin to different depths, targeting different pigment groups such as melanin, hemoglobin, and collagen. IPL can effectively treat various skin problems, including hair removal, pigmentation, redness, and irregular skin texture. IPL can also stimulate the production of collagen, improve skin tone and texture.
Understand laser hair removal technology
The key principle of laser hair removal is to match specific wavelengths of light and pulse duration with specific targets (i.e. melanin in hair follicles) while avoiding surrounding tissue areas. Melanin is a naturally occurring pigment in our skin and hair that is related to color.
Understand diode laser hair removal
The key to the success of diode laser hair removal lies in delivering high energy to the skin. Energy is selectively absorbed by melanin around hair follicles without affecting surrounding tissues.
Diode lasers use light of a single wavelength, which has a high decomposition rate for melanin. As melanin heats up, it disrupts the blood flow to hair roots and follicles, permanently preventing hair growth. High quality laser hair removal machines can protect the skin surface and provide patients with a comfortable and painless treatment experience. The diode laser emits high-frequency, low-energy density pulses, which can be safely used for all skin types.
Understand IPL laser hair removal
Technically speaking, IPL (Intense Pulsed Light) technology is not laser therapy. It uses light with a wide spectrum and rich wavelengths, which means energy cannot be focused on hair and skin areas. Therefore, energy waste is severe, and the selective absorption ability of hair follicles decreases, resulting in poor hair destruction effects. The use of broadband light also increases the possibility of side effects such as burns or pigmentation, especially when the built-in cooling system is not in use. IPL is usually only suitable for lighter skin types.
What is the difference between diode laser hair removal and IPL?
The above treatment methods mean that IPL technology usually requires more regular and long-term treatment to achieve hair removal effects. Compared to IPL, diode lasers have better effects, less discomfort for patients (with built-in cooling function), and can treat more types of skin and hair.
Which laser is most suitable for your beauty business?
In the business world, customers are gods. The essence of diode laser hair removal lies in providing the most effective technology to improve customer satisfaction and bring the highest return on investment to your business. However, not all diode lasers are born equal, so understanding the key factors to achieve this goal is crucial.
Choosing a system that obtains the medical CE mark can ensure stricter product testing and quality. For this purpose, the original manufacturer must obtain ISO 13485 certification.
