The Ultimate Guide to Red Light Therapy
Furthermore the ROS induced by red light act like messengers, telling the fibroblasts to increase in number
and be more active.

This communication happens through special pathways within the cell, kind of like a
messenger highway.
2.3.2 RLT and Photoaging
Scientists conducted a study to see if red light therapy
could improve collagen density, which is crucial for
wound healing and youthful skin.5 Instead of taking
skin samples (called biopsies), they used a painless
ultrasound
(sound
wave)
technique
to
measure
changes in collagen density over time, allowing them
to study the effects without causing discomfort.
The study involved 136 volunteers, with 23 serving

that those who received the therapy had significant
improvements compared to those who did not.
In another study, red light therapy significantly increased the production of key building blocks in the skin,
known as extracellular matrix proteins, by altering gene expression.

These proteins include hyaluronic acid,
which helps the skin retain moisture, and elastin, which keeps the skin firm.
Additionally, the treatment boosted the production of collagen.

These findings
suggest that low-level red and infrared light therapy could be a useful tool for
treating sun damage, potentially providing a convenient at-home option.
