Black sunburned hands even though sunscreen was applied

Sunscreen will help reverse the damage caused by ultraviolet rays, but if used incorrectly, unprotected skin can suffer even more damage.

Burnt skin after a morning outdoors

Hai Phong (a 19-year-old male student) after a morning of participating in the refereeing work for the university football tournament, all exposed skin areas were directly exposed to the burning sun. The skin is from smooth white to dark brown, although before going to the field, he also applied sunscreen to these skin areas.

More ominous, according to the habit, every time he returned from the sun, he would wash his face with clean water to cool his skin. Unlike every cooling sensation, this time he felt a burning sensation as he placed the wet washcloth on his skin.

“Thought that doing so would help keep the skin from burning, but that doesn’t seem right. My friend told me not to wash my face when I come back from the sun. Not sure if this is true? And how can I protect my skin from the sun in this hot summer”, Phong wondered?

Applying sunscreen, it seems simple, but a lot of people do it incorrectly

Dr. BS. Nguyen Ngo Le Minh Anh, Head of Traditional Medicine Skin – Aesthetic Clinic, University of Medicine and Pharmacy Hospital, Ho Chi Minh City – Facility 3, said that when going out in the sun, a hot environment leads to an increase in perspiration, Increases the level of water loss, sebum secretion and lowers the pH of the skin.

When the outdoor temperature rises, the temperature of the skin increases. This is the cause of sweat secretion, the opening and closing of the pores will help the body excrete sweat to lower the skin temperature to a normal state.

Therefore, at this time we should not use cold water to soothe that uncomfortable heat. Because of this, the skin will fall into a state of sudden “heat shock” by the reactions of nerve receptors that are abundant on the surface of the skin.

Dr. Doctor Minh Anh also noted that after going to the sun, open pores should not use cold towels to wipe sweat, but should use dry cotton towels to wipe sweat. Then wait for the pores to close, then we soothe the skin with cool water. You can apply a little cool water to a towel and gently absorb it on the skin, it will help the skin feel much better, the burning sensation immediately disappears.

Sun protection properly

In addition, dermatologists recommend sun protection as one of the most important skin care steps. If exposed to ultraviolet rays day after day without protection, it will cause darkening, dark spots, freckles and premature aging of the skin.

BSCKI. Do Kim Anh, Hospital of Hanoi Medical University, said that using sunscreen will help reverse the harmful effects of ultraviolet rays. However, if used incorrectly, the skin is not only not protected but even more damaged.

Accordingly, this dermatologist said that sunscreen is not for the purpose of protecting against the harsh sun when you have to be outdoors, but is to deal with the ultraviolet rays that exist. invisible all around us.

Therefore, it is necessary to apply sunscreen every day, properly even when not going out in the sun.

“Most sunscreens talk a lot about UVB protection and rarely mention UVA rays. The fact is that UVA rays can penetrate the skin deeper and last longer, and cause premature skin aging.

UVA rays are more active when it’s cool, while UVB rays are more active when it’s hot. Therefore, you should prioritize sunscreen products with a broad spectrum index, with a minimum SPF of 30 and PA ++ or higher, “said Dr. Kim Anh.

Another mistake that many people still make is applying the cream only on exposed skin and not using the correct sequence. But Dr. Kim Anh analyzed, the clothes you are wearing have different thickness, applying sunscreen evenly throughout the body will limit uneven skin tone.

“You need to carefully read the instructions for use, there are creams that promote sun protection right after applying, but there are also types that have to wait about 30 minutes before you can leave the house,” emphasized Dr. Kim Anh.

In fact, some people wonder why they use sunscreen every day but their skin is still dark, even more prone to “sunburn”. The main reason is because they do not pay attention to reapply sunscreen every 2 hours.

Therefore, if you must be active in the sun, you can increase the frequency of reapplying the cream to ensure optimal skin protection. Most experts recommend using a sunscreen with an SPF of 30 or higher, with SPF 30 you can already protect against 90% of UV damage. If the SPF is 60, it does not mean that this product has twice as good sun protection and lasts longer than SPF 30.

First you need to find the right product for your skin, then consider the SPF. Besides, you also need to pay attention to the expiration date of the sunscreen. Don’t regret expired creams, because your skin deserves the best care possible.
