I spy with my little eye something beginning with the letter "L." With no lollipops, laziness, or labyrinths in high-end skin tech, the object spied by your most precious apple could only be LED lights that have flashed big on the contemporary non-invasive skincare scene. How does red light therapy affect your eyes? Can red light damage eyesight? Do you need eye protection, or could you simply close your eyes? Coming right up.

Who amongst us would not trade a bit of their soul for a perfect, unadulterated, doll-like complexion? Is red light therapy for hyperpigmentation effective, or does it make hyperpigmentation worse in some scenarios and what to do about it?

As the popularity of red light treatments grows due to their completely noninvasive character—painless, easy skin renewal with no downtime—questions keep nagging. Is red light therapy safe? Will it hurt your eyes? What if you use it every day? Can red light therapy cause cancer?

Length matters. There is not just one best wavelength for red light therapy. It depends on what you're going for. Are you targeting superficial skin rejuvenation, or do you perhaps need help with muscle recovery or improving deteriorating joint health?

We cling to the hope of a completely non-invasive (but effective) anti-aging method crashing through the orbit of impossibility into our daily skincare routines. Red light therapy is real, scientifically proven to work, and increasingly available in compact, handheld LED therapy devices. Still, the more popular the therapy becomes, the louder the questions: Can you overdo it? How often is too often? And, is the daily use of red light therapy dangerous?

Although non-invasive, very well tolerated, and with very rare to no side effects, red light therapy dangers are real for specific groups and medical conditions. Today, we will explore who should avoid red light therapy or refrain from using it without medical supervision.
