This red light therapy guide is the starting point for our library. If you’re new to red light therapy in Australia, you’ll probably have a lot of questions: what it is, whether it suits you, how to compare devices and what to expect. Each section below gives a one-line summary of a library page and links to it, so you can go straight to the topic you want. Every page sets out what the research shows and where its limits are. We don’t recommend or rank products. If you’d rather work through the library step by step, there’s a suggested reading order for beginners at the end.
This is general information, not medical advice. For advice about your own health or skin, please talk with your GP, dermatologist or another health professional.
