Introduction
Compared to waxing, laser hair removal uses specific wavelengths of light to target and destroy hair follicles, achieving permanent hair removal. Currently, the most commonly used hair removal technologies on the market are diode lasers and intense pulsed light (IPL) systems. For beauty salons, clinics, and distributors looking to expand their business, understanding the differences between these technologies is crucial. This helps them make informed choices, determining which equipment to offer to ensure they meet their clients' specific needs.
What is Diode Laser Hair Removal
Diode laser hair removal is an advanced hair removal technology based on the principle of selective photothermolysis.
This laser device emits high-energy laser light, typically at wavelengths of 808nm or 810nm, which can precisely penetrate the skin's surface and reach the melanin deep within the hair follicle. The melanin in the hair follicle absorbs the laser energy and rapidly heats up, destroying the follicle tissue and preventing its regeneration. Simultaneously, this diode laser employs an intelligent cooling system (TEC cooling) to protect the epidermis during laser operation, significantly reducing pain and improving comfort and safety.
What is IPL Laser Hair Removal
IPL (Intense Pulsed Light) is a broadband photonic cosmetic technology. It is not a single-wavelength laser, but rather composed of multi-band high-intensity pulses of light within the range of 400-1200nm.
This light energy can be absorbed by skin tissue at different depths. Specifically:
• Melanin in hair follicles absorbs the light energy and is heated, thereby destroying the hair follicle's growth function and achieving hair removal;
• Hemoglobin and water in the skin absorb the light energy, stimulating collagen regeneration and improving skin texture.

• IPL devices emit a broad spectrum of light, which is less focused and therefore less efficient for precise hair removal.
• IPL laser treatments typically require 5-6 sessions for the initial hair removal session, usually spaced 4 weeks apart. Fine or light-colored hair may require 8-12 sessions, suitable for short-term hair removal.
• IPL systems are best for light-to-medium tones and can pose risks for darker skin, including hyperpigmentation or burns.
• IPL systems lack advanced cooling, making some users feel heat or mild stinging sensations.

FAQs About Diode and IPL Hair Removal
Q: Is diode laser hair removal permanent?
A: Diode laser hair removal offers long-term or permanent hair reduction rather than 100% permanent removal.
Q: Can IPL be used on dark skin?
A: IPL is less suitable for dark skin tones (Fitzpatrick types IV–VI).
For clients with darker skin, the Diode laser-especially with wavelengths around 808nm or 1064nm-is a safer and more effective option.
Q: Which is safer for beginners?
A: Both Diode and IPL systems are safe when operated correctly, but IPL machines are generally easier for beginners due to their simpler settings and broader safety margins.
Q: How many sessions of laser hair removal are needed to achieve the best results?
A: Diode laser hair removal typically requires 6-8 sessions to achieve permanent hair removal, while IPL usually requires 8-12 sessions.
Conclusion
Both Diode and IPL hair removal machines offer effective, professional-grade solutions for salons and clinics. However, if you aim for long-term, high-efficiency treatments suitable for all skin types, the Diode Laser system delivers better precision, faster sessions, and longer-lasting results. For businesses seeking a multifunctional and budget-friendly entry device, IPL systems remain a solid choice.
At Newangie, we manufacture both technologies, providing OEM/ODM customization to meet your brand and operational needs.
