1, laser technology freckle?
People's Daily Online, Beijing, March 28 (Reporter Gao Yinan) For a long time, pigmentation is a skin problem that plagues many women who love beauty. How to remove freckles has become the focus of their attention.
Recently, Wang Baoxi, chief physician of the Department of Dermatology, Plastic Surgery Hospital of China Academy of Medical Sciences, said in the online popular science consultation of People's Good Doctor client that if you want to remove freckles, you need to know the causes and nature of freckles. Therefore, patients should go to regular hospitals, ask professional doctors to identify and diagnose, and give scientific and reasonable treatment plans.
Wang Baoxi said that chloasma is more common among young and middle-aged women, especially those who are pregnant and have given birth. It is characterized by symmetrical yellowish-brown flaky pigmentation on the face, "related to endocrine changes." Some people may not be able to return it for years. Usually, the treatment of this spot is to adjust the patient's state, and then on the basis of topical drugs, such as tretinoin combined with hydroquinone, if necessary, take the method of fruit acid treatment.
Wang Baoxi pointed out that laser freckle removal is ideal for seborrheic keratosis (senile plaque), freckles and nevus OTA. But for chloasma, a pregnancy spot, it is more difficult, mainly because "laser can not only destroy pigment, but also activate pigment cells." Therefore, we must let experienced doctors use high-quality medical equipment in regular hospitals and never "freckle" in beauty salons.
"Sun exposure and mental factors will also aggravate the condition of chloasma, so it is very important for beauty lovers to do daily sun protection and maintain a good mood." Wang Baoxi said.
