Using them together

A common approach is to cleanse, do your LED session on bare skin, then apply DOSE and moisturiser. Always follow your device's instructions, and ask your provider if you have a light-sensitive condition or take light-sensitising medication.

If you only choose one

A serum is the lower-commitment starting point: thirty seconds, twice a day, no device to charge.

FAQ

Should I apply copper peptides before or after red light?

Most device makers recommend treating clean, bare skin, then applying serum afterward. Follow your device's instructions.

Can red light replace skincare?

It's usually used alongside a routine, not instead of one. SPF is still essential.

Is it safe to combine?

Generally yes for most people. Check your device instructions and ask your provider if unsure.
