UV Radiation,
The Mechanism of Skin Damage.

The mechanism in which UV radiation damages the skin has been discovered. There have been many studies proving that UV radiation can damage the skin and cause skin cancer by accelerating aging, but none of them clearly determined how or why UV radiation damages skin health.

Experiment with UV Light.

The research team at the State University of New York at Binghamton conducted research using skin samples
and analyzed how these skin samples change when they are gradually exposed to more and more UV radiation.
The results showed that stronger UV radiation led to greater damage to keratinases (the protein that helps cells bind together). Since UV radiation deteriorates intercellular coupling on the corneum, your skin peels when you get a sunburn.

Why We Should Put On Sun Protection?

How UV Radiation Affects Our Skin?

We must keep an eye on UVA and UVB that reaches the ground surface and affects our skin.

When Is the Sun Strongest?

UVA is strongest in May - June, and UVB is strongest in July - August, so don't forget to use sunscreen during those months.

The Importance of UV Protection

To protect our body from external germs and bacteria,
it is important to maintain the health of our skin,
which is our body's first defensive layer.
And we must always use sunscreen
to prevent not only skin cancer but also other problems such as infection.

How to Properly Use Sunscreen?

Q: Does higher SPF indicate that it is a better sunscreen product?

A: NO. SPF is marked on sunscreen products, and higher SPF indicates more skin irritation. It is better to use products that are no more than SPF 30 in daily life.

Q: Do young children also need to put on sunscreen?

A: YES. UV radiation may cause more skin damage to younger people, so sunscreen is required. But it is recommended for children older than 6 months since it may irritate the skin.

Q: Does sunscreen block all UV radiation?

A: NO. Sunscreen mostly blocks short-wave UV lights that cause sunburns. Other types of UV radiation must be blocked with makeup, caps/hats, and sunshades/parasols.

Q: Can we put on sunscreen only once before going out?

A: NO. The effect of sunscreen lasts only for a certain period of time, so it must be reapplied after sweating or every 2-3 hours.

Q: Is sunscreen unnecessary on cloudy days?

A: NO. UV radiation is hard to avoid even in the shades
since it is easily refracted or scattered by vapor or air pollutants. It is better to put on sunscreen even on cloudy days.
