Consistency is key for skin transformation. We recommend 10 minutes per day, 4 to 5 times a week. Because skin cells regenerate in cycles, you will see the best results after 4–8 weeks of regular use.

t’s a process called photobiomodulation. When the 660nm red light hits your skin, it is absorbed by the mitochondria in your dermal cells. This stimulates the production of ATP (cellular energy), which allows your skin to repair itself, produce more collagen, and flush out toxins more efficiently.

No. Our LEDs are "cold" lights. While you may feel a slight, gentle warmth from the device’s electronics, the red light itself does not rely on heat to work. It is a photochemical reaction, not a thermal one.

While visible red light is much gentler than sunlight, our panels are very bright. We provide blackout goggles with every device. If you are treating your face, we recommend keeping your eyes closed during the session to avoid brightness fatigue.

None at all. Cells8 devices are strictly limited to the visible red spectrum. There is no UVA or UVB light, meaning there is zero risk of tanning, sunburn, or UV-related skin damage.

Yes. Red light at 660nm is known for its anti-inflammatory properties. It helps to calm the skin and reduce the appearance of redness by strengthening the skin's natural barrier and improving local circulation.

While there is no evidence that red light is harmful during pregnancy, we always recommend a "safety first" approach. Please consult with your healthcare provider before starting any new light protocol while pregnant or breastfeeding.
