Red light therapy is the gold standard for at-home collagen production. Here are the top devices for smoothing texture and firming skin.
Red (633nm) and Near-Infrared (830nm) wavelengths penetrate deep into the dermis to wake up fibroblast cells, promoting collagen and elastin production over time. For a complete overview of all LED masks, see our Best LED Masks 2025 guide.
As we age, our mitochondria (cellular batteries) produce less energy (ATP) and more free radicals. This leads to what we call "cellular senesence"—the cells essentially get tired and stop repairing themselves efficiently.
Red light (633nm) is absorbed by the Cytochrome C Oxidase in the mitochondria. This kickstarts the production of ATP, giving fibroblasts the energy they need to synthesise new collagen proteins.
Near-Infrared light (830nm) reduces inflammation. Since "inflammaging" (chronic low-grade inflammation) is a key driver of skin aging, calming this response preserves existing collagen stores.
Studies substantiate that red light therapy can increase collagen density. This directly counters the thinning of the dermis that happens with age.
Beyond wrinkles, LED improves the overall "canvas". Users report smaller looking pores, faded age spots, and a more uniform complexion.
These areas often age faster than the face. Many modern masks ("bibs") now cover the neck area to treat tech-neck lines and sun damage.
By increasing micro-circulation, LED prepares your skin to absorb expensive anti-aging serums (like peptides) more effectively.

"Unlike instant filters, LED therapy is a marathon. Most users report a 'healthy glow' after 2 weeks, with visible reduction in fine lines typically appearing around the 8 to 12-week mark of consistent use."
