The Foreo Luna device has two main functions; to improve skin cleaning and to stimulate collagen production. The device achieves both of these objectives by utilizing sonic pulsations that are gently applied to the skin.
To cleanse the skin, Foreo Luna has a side equipped with small silicone bristles, which are meant to gently scrub the skin and remove dirt particles. The manufacturer, FOREO, claims that the Luna is so effective that 99.5% of dirt and oil is removed from pores. Further, the company claims that 98.5% of makeup residue is cleared out as well. This is achieved through the combination of the silicone bristles and the 8,000 pulsations per minute that are delivered to the skin.
