In the last article, we talked about what laser is and its application in detail. In this article, we will learn about photons.
What is a photon?
Intense pulsed light with a wavelength of 500-1200nm – pulsed light/strong light/OPT/DPL/colored light are different names for photons, and photons are a wavelength in the spectrum.
This also leads to the different problems they solve. The laser has a deep therapeutic effect due to the same wavelength (single spectrum) and concentrated energy, but the tissue that can be affected each time is relatively single.
Due to its wide spectrum and energy dispersion, photons can affect more target tissues each time than lasers, but each time the treatment effect is weaker than lasers. Because the spectrum emitted by the photonic device at one time is from 500 to 1200 nm, which includes the absorption bands of various chromophores such as water, melanin, and hemoglobin (red blood).
A large number of clinical practices have proved that photorejuvenation can achieve the following seven significant effects on the entire face at the same time:
Remove or lighten all kinds of pigmentation and age spots;
Remove facial redness (telangiectasia) and rosacea; smooth fine wrinkles;
Shrink large pores, thicken skin collagen layer and enhance skin elasticity;
Effectively dilute facial yellow gas and dark circles;
Significantly improves the roughness of the facial skin;
Eliminate or lighten acne scars.
However, some projects that require high-intensity thermal energy cannot be realized (such as acne pits, which require laser means). As mentioned above, the characteristics of lasers are monochromatic (only one wavelength) and high energy and easy to focus, while the characteristics of photons are very broad spectrum (wide wavelength range, from 500 to 1200nm) and divergent (energy is not focused) ).
