Why does the skin turn darker after photorejuvenation?

Does a woman's skin quality really depend on hereditary factors? Perhaps skin color also has genetic factors, but the quality of the skin can actually be achieved through acquired care. However, this requires a certain amount of effort, and all skin care products and high-tech beauty methods must be used. Now many people choose to do photorejuvenation, so why does the skin become darker after photorejuvenation?

1. What is photorejuvenation? What are its functions?

Photorejuvenation is actually a cosmetic treatment using intense pulsed light (IPL, also called "photons") on the skin. Its functions can be roughly divided into two types: eliminating/lightening various skin pigmentation spots; and enhancing skin elasticity.

2. How does photorejuvenation work?

The intense pulsed light emitted by the photon therapy device can change the internal structure of the collagen fibers and elastic fibers in the dermis of the skin, rearrange them, and thus restore their original elasticity; the photothermal effect generated by the photons can heat up, rupture, decompose, and finally fall off the skin pigment clusters.

3. Why does the skin turn darker after photorejuvenation treatment?

Knowing the working principle of photorejuvenation, it is not difficult to understand why the skin darkens. We can imagine a photon therapy device as a giant controllable light bulb. When a light bulb shines, freckles, photodamage and other dark areas of the skin absorb most of the light energy. This is similar to how a black sweater on a sunny day absorbs a lot of heat from the sunlight.

When the pigments in the skin layer (freckles, sun spots, etc.) absorb the light energy from the phototherapy device, the cell structure that encapsulates the pigment will be destroyed. Within a few days or weeks after treatment, these dead cells will gradually rise to the surface of the skin, making the local skin darker than the surrounding skin, which is the darkening of the skin reported by those seeking beauty. As a natural process, these dark areas will gradually fall off and be replaced by non-pigmented skin tissue.

Therefore, skin darkening is actually one of the steps in removing pigment spots by photons, and is a normal reaction of the skin after photorejuvenation treatment. In a sense, the black spots or patches that appear after skin rejuvenation do mean that the photon treatment has achieved good results. After all this unravelling, I believe that you, a beauty-loving person, must have understood why your skin turns darker after photorejuvenation. As for the time it takes for black spots or plaques to fade away, experts suggest that they usually fall off about a week after treatment, and the darkening of the skin is more obvious during the first or second photon treatment.
