Important Factors to be considered on hair removal lasers
For the best result of hair removal, laser energy should be delivered an absorbed selectively on melanin with the higher thermal energy in the shorter time.
Comparison between laser versus light (IPL).
Selectively absorbed in melanin through hair shaft up to follicle
Destroy melanin and adjacent cells
Clinical effect after treatment
Minor erythema around hair treated.
Burning on hair without erythema
Merits and demerits
- Permanent hair removal. - Less energy required due to its high selective-absorption - No risk of burn (on well shaved)
- Temporal hair removal - High energy required as its complex wavelength - High risk of burn
Melanin Absorption Rate of lasers
Pulse Duration (ms)
What is TRT(Thermal Relaxation Time) ? - When laser beam is emitted into skin, thermal energy is transmitted in certain time and the skin recovered from this thermal heat. This recovering time is TRT. In general, during TRT, the thermal energy is reduced gradually, which mean it might not be good in clinical aspect. Therefore, an ideal laser treatment should be done in TRT period or, before TRT.
Thickness of hair and TRT are proportionate. → It requires to treat in various pulse duration depend on thickness of hair !
Recommendation of treatment cases. - Thin hair : Power↑, PD↓(Short TRT) → Necessary High Power - Thick hair : Power↓, PD↑ (Long TRT) → Necessary Long Pulse Duration
For better efficacy, it requires high fluence relatively with a proper pulse duration time.
Some of diode lasers produce high fluence but, more than 30% of those energy are scattered and, not delivered onto skin efficiently.
Cooling part is one of the most essential components in diode laser system. It enables to reduce pain during laser treatment as well as to maximize entire system's performance appropriately.
Patient's pain relief - During treatment patients may feel prick or tingle. This is normal process of procedure by changing to thermal energy from photo energy. Our cooling system relieves this painful feelings.
Minimize risk of side effects - With this cooling system, it is available to radiate with high fluence for better efficacy and patient does not feel strong pain. Some of systems radiates high fluence with long pulse duration but , on the other hand it exposures on high risks of burn or other side effects.
Maximize efficacy of hair removal - As result, the diode hair removal laser system is strongly required to have a good cooling performance so that patients feel less pain, and thus it is available to emit properly high energy into hair shaft without any risk of side effects.
