Article This article discusses our take on TRTs in a (relatively) non-mathematical way. It discusses tissue denaturation using the Arrhenius Damage Equation which describes the ‘change of state of one species into another’. It also introduces the concept of ‘Omega’ – a parameter which describes the amount of tissue damaged by the heating process. I… Continue reading “Thermal Relaxation Times” – Body Language magazine

“Thermal relaxation times: an outdated concept in photothermal treatments”

Article This is an article I co-authored with my good friend, PA Torstensson, about our interpretation of the idea that thermal relaxation times (TRTs) can be used to determine the pulse duration of laser energy when applied to skin conditions (hair, blood vessels etc). We disagree with this idea – as the title hints at!… Continue reading “Thermal relaxation times: an outdated concept in photothermal treatments”
