The Difference Between IPL and Diode Laser Hair Removal

Many people struggle with whether to choose IPL or diode laser when choosing laser hair removal. Actually the hair removal effectiveness of Diode Laser vs IPL is the main difference, let's see what is due to the difference between them, it is important to understand the difference between Diode Laser and IPL.

Principles of Laser Hair Removal

Laser hair removal is based on the principle of selective photothermal, matching specific wavelengths of light and pulse durations to specific targets. That is, the melanin in the hair follicle absorbs the light beam emitted by the laser, and the light energy is converted into heat energy, destroying and destroying the tubular follicle (hair follicle) in the skin that can produce hair, so as to achieve the purpose of hair removal.

IPL Laser Hair Removal

IPL (Intense Pulsed Light) light-based energy technology uses a broad light spectrum ranging from 400nm to 1200nm. Filters are used to filter out unwanted frequencies and allow desired wavelengths to target specific structures and chromophores in the skin. However, there will be a lot of energy waste and less selective absorption in the hair follicle when the broad light band acts, resulting in less effective damage to the hair. Using broadband light also increases the potential for side effects, especially if integrated cooling is not used.

Diode Laser Hair Removal

Diode lasers use a single wavelength of light that has a high absorption rate for melanin. At the same time it incorporates a skin cooling function to protect the skin surface and surrounding tissues. When melanin heats up, it damages the hair roots and blood flow to the follicles, and permanently disables the hair. Diode lasers capable of delivering high frequency low energy density pulses can be used safely on all skin types.

The difference between IPL and diode laser hair removal

Typically, IPL techniques require more regular and longer-term hair removal treatments, while a single wavelength of diode lasers is better for hair removal, as well as potentially more effective in reducing discomfort (integrated cooling), and can treat more hair with that wavelength Skin and hair type. IPL is best for people with light skin and dark hair.
