What are sun spots?

Many people always think of choosing a leisure place to travel and relax in their spare time, and these will become the direction indicators for many people's choices. However, when we are having fun, we often neglect some details, which leads to some subsequent troubles after the holiday, such as sunburn and sun spots. For women, the appearance of sun spots is not just an annoyance. So let’s take a look at what sunburn is like!

Sunspots are obviously the result of excessive exposure to the sun. They are an acute inflammatory reaction of the skin. This is mainly because after women have been exposed to ultraviolet rays for a long time, ultraviolet radiation has a certain stimulating effect on the dermis of normal human skin, causing it to release a variety of inflammatory mediators such as histamine, 5-hydroxytryptamine, and kinins from cells. Once these inflammatory mediators increase, they will dilate blood vessels and increase permeability, and pigmentation reactions on the skin will become sunspots. Therefore, people with sunburn generally have visual manifestations on their skin such as erythema (bright red in color), edema, blisters, pigmentation, etc., and generally feel burning or stinging in severe cases. However, due to different individual conditions, not all cases require laser treatment. Some mild cases will disappear automatically after 2-3 days with ice compresses or facial masks. For severe cases, it is recommended to go to a regular institution for medication or choose safe methods such as laser removal.

A. How to remove mild sun spots - medication

The so-called mild cases generally refer to symptoms such as obvious redness and swelling of the skin, and the redness and swelling will be slightly relieved after ice compresses or body wraps, and then some drugs are used to eliminate the inflammatory response. For mild cases, antihistamines are mainly used, but the specific medication also needs to be targeted according to the patient's individual situation and skin condition. Therefore, patients are reminded not to take medication at will, and they must be under the correct guidance of experts from regular institutions.

For patients with severe sunburn, due to severe pigmentation, ordinary drug treatments will inevitably be ineffective in removing sunburn. Although there are many ways to remove sunburn with medical cosmetic technology, both safety and effectiveness must be considered. Laser sunburn removal is currently one of the more recognized safe methods. Many regular institutions have carried out this method and have successfully solved various skin problems for many people, including sunburn. The laser method of removing sun spots is mainly to use laser energy of appropriate wavelength to act on the skin. After the energy is focused, it penetrates the epidermis or dermis and is absorbed by pigment cells. Under the effect of high temperature difference, it causes micro-explosion and is crushed into small particles that are swallowed or excreted from the body to achieve the freckle removal effect.
