"What is red light therapy?" is a question that's frequently brought to dermatologists, skin experts and beauty editors alike. LED light therapy – including red – has been linked with helping with many major skin concerns, from hyperpigmentation and acne to fine lines and dullness.
What's more, thanks to new at-home devices, red light therapy is more easily available in our skincare routine than ever before. “LED light therapy has been used for over 30 years to help accelerate wound healing as well as to stimulate the production of collagen and elastin,” says Dr. Maryam Zamani, founder of MZ Skin. It was first developed by NASA to help astronauts with tissue healing and repair in space and, she adds, "has evolved to also help skin cells absorb topical skincare products more effectively."
