1. Sunburn overview


Sunburn is a condition in which the skin becomes red and burning to the touch, usually many hours after exposure to UV rays in the sun or other artificial light sources.
Repeated exposure to sunlight causes skin burns and increases the risk of many other damage such as skin aging, melasma, peeling and skin cancer. Many remedies to help reduce sunburn can be done from simple home remedies. Sunburned skin usually takes several days to heal or even longer. In addition, it is necessary to take skin protection measures when playing or working outside, even on cool days to protect the skin and prevent sunburn.

2. Why does sunburned skin darken?


A lot of people wonder why the more sun protection, the darker the skin, in fact, because the sunburned skin condition appears due to the skin being too exposed to ultraviolet rays (UV rays). Ultraviolet radiation has a wavelength too short to be seen by the human eye. UV rays are divided into several groups based on wavelength, including two main groups, UVA and UVB rays. UVA rays are the rays that are capable of causing skin aging damage, while UVB rays are the main cause of skin burns. Exposure to ultraviolet rays including both UVA and UVB rays increases the likelihood of skin cancer occurring. Tanning beds are capable of producing UV radiation, which can also cause sunburn.
Melanin is a pigment located in the epidermis of the skin, which determines the normal skin color of each person. UV rays are factors that stimulate the body to increase melanin production and cause skin to darken. This is a response that protects the body from sunburn and further skin damage. However, the amount of melanin produced in each person is determined by the genome and many people do not produce enough melanin to protect the skin. At that time, UV rays cause burning, pain, swelling and redness of the skin.

Skin can burn and darken even on cool days and cloudy days. More than 80% of UV rays can penetrate clouds and reach skin. Water, sand, snow and other surfaces can reflect UV rays, causing skin burns to the same extent as direct exposure.

There are many simple remedies that can be done at home for sunburn. People with sun-damaged skin can apply the following substances to their skin to relieve symptoms, including:

5.1. Cool water


Sunburn is simply understood as an inflammatory response of the skin. One of the easiest ways to reduce inflammation is to lower the temperature of the affected area. An effective way to relieve the immediate burning sensation is to jump into water or splash with cool water. However, be wary of pool water as the chlorinated water there can be more irritating to the skin. Using ice directly on the surface of the skin should be avoided as it can cause more damage to the sunburned area.

5.2. Baking soda and oatmeal


Mix a few tablespoons of baking soda in the shower with cool water and soak in it for about 15 to 20 minutes to help reduce the damage on the skin. Oatmeal can be added to soothe irritation and restore natural moisture in the skin. Do not rub your skin in the shower and afterwards, just blot the water with a soft cloth.

In addition, some of the following measures are also effective when the skin is sunburned and dark:
Wear light and light clothes: when the skin is sunburned, you should choose clothes that do not cling to the surface of the skin. The skin is the largest organ of the body so it is best to allow the skin to breathe and recover from damage such as sunburn. Materials from natural fibers such as cotton are a good choice in this case. Drink plenty of water: When sunburned, the skin needs more moisture to recover. Drinking lots of water is a simple and effective measure. Use moisturizer: in addition to the initial treatment, the skin needs more gentle care. One of the most important things to do to prevent flaking is to apply moisturizer to the damaged areas. Should choose special creams for sensitive skin, especially without colorants and fragrances to limit skin irritation.
