Laser & IPL Core Knowledge
How lasers and intense pulsed light work, tissue interaction, wavelengths, pulse duration, fluence and cooling.
About this course
Laser and IPL treatments are only as safe as the practitioner's understanding of light. This course covers the physics in practical terms: how laser light is produced and how it differs from IPL, wavelength and chromophores, selective photothermolysis, pulse duration and thermal relaxation, fluence, spot size and cooling, and how these settings change the effect on tissue.
It is device-independent theory. It supports the core knowledge expected of laser practitioners in the UK but does not itself certify competence on any device.
Who it is for: Anyone entering laser or light-based treatment, and practitioners refreshing their core knowledge.
What you will be able to do
- Explain how laser and IPL light is produced and how they differ.
- Describe wavelength, chromophores and selective photothermolysis.
- Explain pulse duration, thermal relaxation time, fluence and spot size.
- Describe cooling methods and their purpose.
- Relate settings to tissue effect and risk.

Theory and professional development. This online course provides theory and professional development. It does not, by itself, confirm hands-on practical competency. Where practical competency is required, appropriate supervised practical training and assessment should also be completed. The Academy delivers that practical training in Chichester, Petersfield and Eastergate.
