Objectives: Lasers hair removal remains one of the most common procedures in cosmetic dermatology and it has always been challenging because of the higher competing epidermal melanocyte. It is also very intricate as the targeted hair chromophore is also melanin.
Introduction: As a result, to avoid unwanted side effects from laser therapy while maintaining high efficacy levels, the use of the right laser device, appropriate settings and customized pre and post-treatment care are crucial. With more Lasers and more efficient versions of existing lasers in the market,the safety profile has been taken care of without compromising the efficacy. Diode lasers along with long pulsed Nd:YAG and Alexandrate are considered as the safest hair removal lasers ,as Ruby and IPL are rarely used these days. However Diode lasers still remain the gold standard in Laser Hair removal.
Materials / method: Some manufactureres believes in In Motion technology while some still follow the stack mode.Offlately there has been emergence of multiple wavelengths from the same handpiece,for example 755,810,1064 nm or 810,940 &1060 nm with the the percentage of each wavelength in a single shot being divided and while there has also been emergence of a laser in the market where two wavelengths namely 755 & 1064nm delivered within the same laser machine, delivering each wavelength according the treating physicians need.This system functions like 2 technologies in one platform.
Conclusion: Multiwavelength platforms seems to be the way forward ,however the basic principles and certain problems like minimal pain,treating thin hair,paradoxical hair growth, white hair removal still remains a challenge.
