In the 1980s, NASA sought innovative ways to grow food in space, addressing challenges like zero gravity and limited sunlight. By 1995, their experiments with LED technology led to successfully growing potatoes aboard a space shuttle.
Unexpectedly, scientists working under these LED lights noticed that cuts and abrasions on their skin healed faster and appeared smoother.
This discovery spurred years of research into LED therapy’s potential. Studies on cells and animals confirmed accelerated healing and skin regeneration, prompting NASA to collaborate with medical experts for human trials.
These trials showed that LED therapy boosted collagen production, improved elasticity, and revitalised skin, leading to the development of Low-Level Light Therapy (LLLT).
Meanwhile, in the 1960s, microcurrent technology emerged in the medical field to help stroke patients regain muscle function. Researchers later found that gentle electrical currents could also tone facial muscles, improve skin elasticity, and enhance firmness.
As one expert noted, “Microcurrent mimics the body’s natural electrical signals, encouraging skin and muscles to heal, repair, and strengthen.”
Today, the combination of LED therapy and microcurrent technology has revolutionised skincare. Together, they address sagging skin’s root causes by boosting collagen, toning facial muscles, and improving elasticity—all without invasive procedures.
