What does it mean “cleared by the FDA”?

When it comes to LightStim, it means nothing.
The FDA doesn’t say that LED light of any wavelength will improve your skin health. It only says that LightStim is similar to another product in the market.

The red light will help lettuce seeds germinate because lettuce seeds have receptors for red light (and UV light). Your skin doesn’t.

Before you spend money on an LED device for your skin, ask yourself. Am I a lettuce seed? If you are not, spend your money on a Skin Actives product. Your skin will be grateful.
