Light doesn’t just “zap” the skin — every wavelength has a specific target.
Melanin, haemoglobin, water — each absorbs light differently. That’s why a laser tuned for hair removal won’t touch broken capillaries, and why the wrong wavelength on the wrong skin type isn’t just ineffective — it’s risky.
This principle is called selective photothermolysis, and it’s the foundation of every safe laser and IPL treatment.
It’s exactly where we start on our 1-Day Core of Knowledge: Laser & IPL Theory course.
