Homecare is the largest end‑user segment — you buy a device online, use it on your couch, and treat yourself. But dermatology clinics are the fastest‑growing. The light therapy market research study shows that clinics are growing at over 6% CAGR, because they offer higher‑powered devices and professional oversight.

What's the difference? A home LED mask has 100‑200 LEDs. A clinic device has thousands, delivering 10x the energy. The light therapy market trends highlight that the fastest‑growing application is psoriasis, which requires narrowband UVB (NB‑UVB) — a wavelength not available in home devices.

But clinic visits are expensive and time‑consuming. That's why many patients start with home devices, then escalate to clinic treatment if needed.

The bottom line: for mild acne or winter blues, home devices are fine. For psoriasis, vitiligo, or severe acne, see a dermatologist.
