Some people who finished the fractional co2 laser freckle treatment, will find that their skin becomes dark. But please don’t worry, it is the normal phenomenon. Please don’t worry. 

Then what is the reason? 

In fact, many pigment spots are not only present on the epidermis but have a certain depth. The spots we see every day are very likely to be the "tip of the iceberg" rather than the full picture of the spots.

And laser freckle removal requires a certain amount of power to crush the entire iceberg.

Therefore, it will produce a certain degree of irritation to the skin and form very small wounds. The skin is prone to inflammation such as mild redness and swelling. Pigmentation will appear during the recovery process of inflammation, which is the anti-black phenomenon we see. Called "Pigmentation after inflammation", this is a normal response after laser treatment, without being overly stressed.

The principle of fractional co2 laser freckle removal:

It can selectively act on different skin tissues, as long as a specific light source is used to ensure that it only has an effect on stains, and does not affect normal skin tissues.

Does the laser thin the skin?

The skin has a powerful regeneration function. The epidermis is composed of multiple cell layers, and the dermis is mainly composed of collagen fibers, reticular fibers, and elastic fibers. Even if we do not undergo any treatment, they are constantly renewing themselves, the cycle is about 28 days.


As we age, our own metabolism will become slower and slower, and the renewal speed will not keep up with the natural loss rate, and improper skin care products will gradually thin the skin and lose its elasticity.
