But is the hot sun on the beach worrying you again? If you don't want to be tanned, you should be covered with a thick and sticky high-index sunscreen? Do you really have to apply sunscreen every hour? The sunburned skin will be red, swollen and painful. What should I do? Here are a few tips for using the sunscreen for the beach, so you can enjoy the leisurely vacation of the sunny beach.
Raiders 1: "Why is it particularly easy to get sunburn by the sea?"
Understand UV
The ultraviolet rays are classified into three types: UVA, UVB, and UVC. UVA is also a long-wave ultraviolet light, which can directly reach the dermis layer, destroying elastic fibers and collagen fibers, causing the skin to lose its elasticity. At the same time, it can make the epidermis tanning and damage the skin most deeply. UVB is also the long-wave in ultraviolet light. The main cause of tanning and causing burns within 48 hours. Most UVCs are reflected off the skin, so it is the least harmful to the skin, but it still causes water loss from the epidermis and fine lines.
In addition, in addition to the direct sunlight from the sky, the light reflected from the ground can also cause damage to the skin. The reflectivity of different reflective surfaces is very different, the lawn is 1% to 2%, the asphalt surface is 5% to 6%, the beach can reach 15% to 20%, and the water surface is 10% to 100%. The reflectivity of the beach and water facing the sun is very high, so when the beach is in the sun, even if the sun is not very strong, special sun care is needed.
Raiders 2: "Is 50 times more sunscreen really necessary?"
Correct selection of SPF PA values
Usually, you can use SPF15-20/PA++ sunscreen products, but if you want to walk on the beach, only SPF sunscreens are not enough. At the same time, UV sunscreen products are needed to protect against UV rays. Although it is recommended to use products with higher sun protection factor, such as sunscreen with SPF value above 30. However, the higher the SPF value is, the better the skin will be. If the SPF value is higher than 30, the oily ingredients and sensitive ingredients will increase significantly. The use of too oily sunscreen skin care products will increase the burden on the skin and cause skin allergies. So is there a need for SPF50 sunscreen that is legendary to go to the beach? It depends on the time you want to stay at the beach. If you want to dive or may be exposed to the sun for a long time, you can carry SPF50/PA++ sunscreen with you at any time.
Raiders 3: "Is it necessary to make up every hour?
Correct sunscreen
If you use a chemical sunscreen, apply it 20 minutes in advance in the room before going to the beach. Chemical sunscreens take some time to adhere to the skin to form a protection. Carry a bottle of physical sunscreen spray with you and it is best to apply it once a hour. After swimming in the sea, you should immediately wipe the sunscreen completely. Salt in seawater is not irrigated in time and will adhere to the skin to oxidize the skin. Therefore, it is strongly recommended to add a barrier before the sunscreen. It will form a film on the skin surface, which can let the sweat out, and let the sea water crystallize after evaporation. The small particles are separated.
Raiders 4: "Why is it sunburn when sunscreen is applied?"
Post-sun repair is more important
Sunscreen does not leak water, it does not mean that you can rest assured when you come back from the beach. Sun protection is against sun damage, and temperature and sea breeze damage the skin.
Timely cooling: Wrap the skin with high temperature with a refrigerated ice towel or gauze. After cooling for 15~20 minutes, you can use the iced watermelon or cucumber slices to hydrate and cool the skin.
After sunburn repair: The skin after exposure is very fragile. At this time, although it is urgent to hydrate and whiten, don't overdo it. After calming the skin, you can use the cotton pad to soak the toner to foundation the skin, then apply the mask to the reddish skin after sunburn to deeply repair and moisturize the skin.
