1. Brief description.
When using picosecond laser to treat age spots, I believe everyone will encounter the problem of “blackening again” after the treatment of age spots. Many people ask, after the scabs are removed, the age spots are indeed gone, but after about a month, they grow again. How to solve this?
First of all, this phenomenon does not mean that age spots grow again, because the spots that have been removed cannot grow so fast. This is a manifestation of post-inflammatory pigmentation, that is, PIH, so the core point of solving it is to solve the pigmentation.
Post-inflammatory pigmentation (PIH) mostly occurs in Asians, and the degree of post-inflammatory pigmentation is closely related to skin color, degree and depth of inflammation, degree of basement membrane damage and melanocytes.
It is also affected by some human factors, such as abnormal shedding of scabs, and secondly, failure to do a good job of sun protection and repair. These are the causes of post-inflammatory pigmentation.
PIH usually resolves on its own, but it may take months or even years, and some may be permanent. If you want to reduce pigmentation as soon as possible, repairing the skin barrier is the most important step, and repair needs to be carried out throughout the entire treatment process before and after surgery.
2. Skin repair principles (how to prevent pigmentation).
2.1 Moisturize the skin before treatment.
Age spots are generally treated with Q-switched/picosecond lasers, which are lasers that are more likely to cause skin allergies. In addition, age spots are generally treated until scabs are formed and peeled off, which is more irritating to the skin. Therefore, preoperative moisturizing is particularly important and is one of the preventive measures to reduce postoperative allergic reactions.
Preoperative moisturizing can choose some masks/sprays/emulsions with simple ingredients, such as repair dressings, skin care water, repair spray, etc.
2.2 Skin repair after treatment.
Collagen and growth factors should be used during the scab stage. Collagen and growth factors are endogenous components of the skin. The use of collagen and growth factors during the scab stage can provide nutrients required for cell synthesis and accelerate skin repair.
After the scab falls off, the skin is in a red state. At this time, anti-inflammatory and repair are needed simultaneously. Licorice and growth factor ingredients can be used to stimulate the skin to accelerate epithelialization while anti-inflammatory. The above repair methods are necessary to prevent postoperative pigmentation.
In addition, it is necessary to do a good job of sun protection. Apply sunscreen or do a good job of physical sun protection.
Examples of products that can be selected: type III collagen gel, complex peptide repair essence, licorice liquid, clear sunscreen, etc.
3. How to solve the problem of skin pigmentation?
3.1 Early stage of pigmentation (redness), IPL treatment.
At this time, you can use IPL intense pulsed light, choose an anti-inflammatory treatment head, 580nm or 590nm wavelength, intense pulsed light can penetrate the skin, and be preferentially absorbed by the water and capillaries in the skin tissue. Heat energy can coagulate the blood in the capillaries without destroying normal skin tissue. Hemoglobin selectively absorbs photons and the temperature rises and coagulates, and conducts heat to the surrounding blood vessel walls, thereby destroying the endothelial cells of the blood vessel walls and the blood vessels themselves, which can inhibit capillary dilation and solve the problem of skin redness.
Examples of repair products that need to be used: complex polypeptide repair essence, licorice serum.
3.2 Stabilize pigmentation and remove it in picoseconds.
At this time, you can use Q-switched/picosecond lasers, with large spot and low energy light sweeping. At this time, the pigment target tissue in the skin is exploded and disintegrated, part of the scab falls off, and part of the residues destroyed by lymph, macrophages, etc. are absorbed and metabolized to achieve the purpose of removing pigment. Or do some mesodermal projects to repair the skin base and accelerate pigment metabolism.
Examples of repair products that need to be used: L-vitamin C stock solution, niacinamide essence.
4. Article summary and learn more.
Therefore, after using picosecond laser to treat age spots for one month, the darkening again is caused by inflammatory pigmentation.
To treat pigmentation, we need to distinguish whether the pigmentation is in the early stage or the late stage. Early pigmentation requires IPL beauty machine for treatment, and late pigmentation requires picosecond laser with large spot area and low energy density for cleaning and removal.
