When spots appear on the face, most beauty lovers do not take it seriously and will habitually use cosmetics to cover them up, in fact, this will not only solve the problem but also become worse, so how do spots actually change? First of all, we need to understand how the spots are produced. At the bottom of our epidermis is the basal layer, which constantly produces new epidermal cells to protect our skin and renew it, the base of melanin is here, and it is also the main barrier to prevent skin damage. (Melanin helps absorb UV rays in case of high exposure, prevents our skin from sunburn, reduces skin damage, and it also determines our skin tone.) When exposed to external stimuli our skin is in a state of “self-protection” and the melanocytes in the skin secrete a lot of melanin to protect the skin from damage. When the melanocytes secrete too much and the metabolism of the skin is not enough, melanin will be deposited on the surface of the skin and pigmentation will be formed. So what kinds of pigmentation are there? Pigmentation is divided into superficial pigmentation and deep pigmentation, and the common clinical ones are freckles, sun spots, chloasma and age spots. They all belong to pigmented skin diseases. Due to the increase of melanin particles in the skin, it is a common brownish or melanin-depigmented, disfiguring skin disease on the face, mostly on the cheeks and forehead. How to treat pigmentation? Ultra picosecond, using holographic pixel focusing technology, fast and powerful energy directly shatters melanin, destroys melanin into tiny dust-like, which is easier for human body to metabolize, and achieves pigment removal, skin whitening and rejuvenation through multi-dimensional treatment. By using specific wavelength laser to irradiate the pigmentation, under the principle of selective photothermal action, the pigment particles in the skin absorb the laser. The pigment particles rapidly expand and rupture after selectively absorbing high laser energy in an instant, prompting the melanin vesicles in the melanocytes to be destroyed, engulfed by the nearby phagocytes and finally discharged from the body with the body’s metabolism. This technology is not suitable for all people such as: 1. pregnant women; 2. people who are allergic to light; 3. people with heart disease; 4. people whose treatment area is being allergic, inflamed, herpes, skin infectious diseases, or even have large wounds. All are not suitable for treatment with the ultra picosecond laser. There are many advantages of ultra picosecond technology, safe and no side effects. No pain. It can be promoted in a large area.
