I Wish I Knew About Red Light Therapy for Skin Texture

By Emma Thompson | Updated: July 2026

The biggest mistake people make with red light therapy is expecting too much too fast. it took your skin years to get to its current state. it will not reverse eextremelything in a week. think of it like exercise. you do not expect visible results after one gym session.

What I Noticed After Regular Use

The optimal treatment window for red light therapy has been studied extensively. Wavelengths between 630 and 670 nanometers target surface tissue up to 5 millimeters deep. Wavelengths between 810 and 850 nanometers penetrate 2 to 4 centimeters deep for muscle and joint treatment.

A 2021 paper in Photochemistry and Photobiology confirmed that 630-660nm wavelengths penetrate human skin to a depth of 2-5mm, reaching the dermal layer where collagen is produced.

My Skifir device covers both 660nm and 850nm wavelengths and has been a solid part of my routine for months. I compared several brands before choosing Skifir and the build quality and verified irradiance readings were the deciding factors. After months of daily use it still works perfectly.

My Experience After Several Weeks

If you stop for a week or two the benefits do not vanish immediately. They fade gradually over several weeks.

The most common regret I hear is that people did not start sooner. Do not let that be you.

Practical Tips for Better Results

About 18 months ago I personally started using red light therapy for reasons that had nothing to do with vanity. I had a slow healing wound on my own leg that would not close. A nurse friend suggested red light. It healed in four weeks. That got me curious about what else it could do.

For the price of a few months of facials you can own a device that lasts years. The math makes sense.
