Why is picosecond laser "dark spot removal" useless? Doctor: If you fail to do "6 things" after surgery, the effect may be greatly reduced!
Even though picosecond laser and skin-cleansing laser are effective, why can’t dark spots go away? A woman in her 30s has been troubled by dark spots for a long time. After careful consideration, she decided to use laser to improve the treatment. However, not only did the dark spots not disappear after the operation, but the melanin deposition became more obvious. Dr. Hu Yixuan, deputy director of Jingyan Dermatology Clinic, pointed out that many people have incorrect perceptions of laser, thinking that laser can completely resolve dark spots “once and for all”. However, if adequate sun protection is not done after surgery, it will appear again once exposed to ultraviolet rays. Make dark spots recur.
The problem of dark spots is not only related to sun exposure? Are hormones and genetics also the culprits of spots?
The root cause of the dark spot problem may vary from person to person. Dr. Hu Yixuan pointed out that from the perspective of the mechanism of dark spot formation, there are many melanocytes distributed under the epidermis of human skin. After receiving specific stimulation, they will begin to activate and produce melanin, which is concentrated in specific areas. Class points were formed only after the district was established. For example, the hereditary “freckles” problem that troubles many people is that there are light spots on the cheeks, nose, and forehead, and different shades of color will appear with sunlight exposure. As for “sunspots”, which are often caused by exposure to ultraviolet rays, they are different from freckles in that they are not limited to the face and are usually larger and more obvious.
The “zygomatic mother spots” and “Ota mother spots”, which are also hereditary dark spots, are usually darker and often appear on the cheekbones. As for the common “liver spots”, they are mainly affected by female hormones, such as the progesterone secreted during menstruation and pregnancy, which is also related to the production of melanocytes. In addition to genetic factors, ultraviolet exposure and hormonal influences, stress in daily life may also be factors that stimulate the formation of dark spots. For example, being under great pressure at work can lead to fatigue, illness, etc., which can cause “chronic inflammation” in the body and may also induce the formation of dark spots.
Will drinking coffee and eating citrus make your skin darken? Is exfoliating with a scrub too harmful to your skin?
I usually use skin care products but my dark spots are not reduced but increasing? Dr. Hu Yixuan explained that some people have incorrect concepts of facial cleansing. For example, using facial cleansers and scrubs that are too powerful in cleansing or excessive “exfoliation” will cause the skin to lose its protective power and become prone to damage and inflammation. Produce melanin precipitation. Similarly, inappropriate skin care products and cosmetics will also burden the skin after long-term use.
As for the rumor that eating citrus fruits and drinking coffee can easily make your skin “dark”, is this true? Dr. Hu Yixuan explained that the former is mainly because citrus fruits are rich in “furanocoumarins” photosensitive substances. If they are in direct contact with the skin and exposed to ultraviolet rays, it is easy to form “phytosolar dermatitis” and lead to melanin precipitation. As long as caffeine is not consumed excessively, it is not the direct cause of melanin precipitation for the average person.
How should I take care of myself after picosecond laser treatment? “1 ingredient” has been proven by literature to help prevent darkening and brighten skin
Dr. Hu Yixuan reminds that for existing melanin problems, many people will use laser to help skin metabolism, such as skin-cleansing laser, picosecond laser, etc. However, the care and maintenance after laser has an important impact on skin quality. . Generally speaking, 1-3 days after laser treatment is the key recovery period. Redness and swelling can be relieved through ice compresses and medications. At this time, it is very important to provide adequate moisturizing and repair. Try to use mild skin care products with few additives. After your skin stabilizes, you should continue to use sun protection.
Dr. Hu Yixuan pointed out that skin care products should mainly be natural and have credible ingredients. You can choose active ingredients that block the production of melanin, such as “tyrosinase” and natural berry extract, and pay attention to whether the literature has proven its melanin-blocking effect. At present, the Darkening and Whitening Essence has been published by a laboratory in Lyon, France, and it has been verified that it can reduce 29% of the precipitation caused by ultraviolet rays after being used in the morning and evening for 7 days. It is obviously helpful for long-term skin care and blackening and whitening.
It’s not just fried food that’s a maintenance mine! How to avoid melanin precipitation after surgery?
Dr. Hu Yixuan said that there are hundreds of reasons for melanin precipitation. In addition to uncontrollable genetic factors, daily routine and maintenance concepts also have a profound impact. It is recommended that people with melanin problems should pay attention to their daily routine and avoid overexertion or illness. These inflammatory problems will cause an increase in free radicals in the body, which is more likely to cause cell aging and induce melanin precipitation.
In addition, if you want to avoid anti-blackening and precipitation, you can consume more fruits and vegetables rich in vitamin C in your diet to increase the protective factors in the body, reduce heavy flavors and fried foods to reduce the generation of free radicals, and supplement good fats and oils such as unsaturated fatty acids. You can choose fish oil and vegetable oils such as olive oil and soybean oil, which are also helpful in increasing the protection of the skin surface.
