What is the difference between red light and infrared on this device?

Red light sits in the visible range and is used mainly for skin. Near-infrared is invisible and penetrates deeper, which is why panels pair the two. The RT500 runs both from the same panel.

How often should I use it?

Most at-home panel routines are short sessions several times a week, kept consistent over weeks. Follow the session time in the manual rather than longer sittings, since more time is not better with light therapy.

Do I need eye protection?

Yes. Bright red and near-infrared panels are intense at close range, so wear the supplied or recommended eye protection and keep your eyes closed or turned away during sessions.

Red light therapy is generally well tolerated, but check with a doctor first if you take photosensitizing medication, are pregnant, or have a skin condition. Stop if you notice irritation.

How does it compare with a handheld red light device?

A panel like the RT500 treats a larger area in one sitting, which suits face, chest or back routines. Handheld wands are more targeted but take longer to cover the same area.

What should I check before buying?

Confirm the wavelength and irradiance figures and the warranty terms, since Garvee publishes less of this than premium brands. Also check the panel size against the area you want to treat.
