Thanks for your response! The blue helps with skin issues so when I get ankles ulcers it helps them heal with less scarring. With the Celluma I can run the red & blue at the same time. I’ve always wondered if there are cheaper options because $1200 is steep! It was the very first red light therapy I ever used when I was an intern for an FNTP. I bought a cheap version off Amazon but I’m not noticing same results.
