Why is the number of Joules important?
Joules equal the number of watts per square centimetre per second, and the higher the number of joules, the more energy (in conjunction with your skin type) we’re able to get down to the target cells. When a hair is successfully eliminated, that’s the end of it, but when a hair is targeted and the treatment fails due to insufficient power, a natural defence process kicks in. The body realises that its cooling system is under attack, and strengthens the hair against later attacks, i.e. further treatments. The hair grows thicker, the root grows in size, and the surrounding tissue tightens its grip on the hair. Our waxing rooms see the results of low-joule light treatments every day.
