[Doctor's Column] The First Step to Maintaining Youthful Skin: How to Use Sunscreen A to Z

 

SPF and PA: What the Numbers Really Mean

What we see every day SPF/PA is not just a simple number, but an important indicator that indicates how much UV rays can be blocked. For healthy skin, it is important to choose a product with both high SPF and PA indices.

▲SPF (Sun Protection Factor)

Index that blocks ultraviolet B (UVB) rays that cause skin burns and skin cancer . A higher number means a longer blocking time.

▲PA (Protection Grade of UVA)

Penetrates deep into the skin main Index that blocks ultraviolet A (UVA) rays that cause photoaging such as wrinkles and pigmentation The more '+' there are, the stronger the blocking effect.

 

What is the difference between a weaponized vehicle and an organic vehicle?

Sunscreens are broadly categorized into "inorganic sunscreens" and "organic sunscreens," depending on their ingredients. Understanding the pros and cons of each type and choosing the right one for your skin type is key.

▲Weapon-based vehicles (physical barriers)

Reflects and scatters ultraviolet rays by forming a physical film on the skin It blocks UV rays. It's gentle on the skin, making it suitable for sensitive skin. Its effects are noticeable immediately upon application. However, it may appear cloudy or feel sticky.

▲Organic sunscreen (chemical sunscreen)

A method of absorbing ultraviolet rays into the skin, breaking them down through a chemical reaction, and releasing them as heat. It blocks UV rays. It has little white cast and spreads well. However, the chemical ingredients can cause eye irritation or skin irritation, and the effects can be seen after 20 minutes of application.

 

Recently Many hybrid vehicles have been released that combine the advantages of both. It is being done. It is being opened in Maypure. Liviheal Exosome Sunscreen is a mixed sunscreen product It is characterized by being free of harmful ingredients and white turbidity and having a smooth application.

How to use sunscreen correctly

No matter how good the sunscreen is, it won't be effective if you don't use it properly.

▲Amount to apply

When applying to the face Take an amount the size of a 500 won coin and spread it thoroughly. If the amount is too small, you won't see the full effect indicated. Generally, a good amount is enough to fill two index fingers.

▲Reapplication cycle

Because it is easily erased by sweat and oil, When doing outdoor activities, the rule is to reapply every 3 to 4 hours. Even if you are indoors, it is recommended to reapply if you are by a window.

 

Best UV protection tips to take together

I know that applying sunscreen regularly and in the right amount is important, but realistically, it's difficult to do so every time. So Using sunscreen + physical blocking in daily life together It is recommended to do so.

▲Sunglasses ▲Hat ▲Umbrella, etc. Physically block sunlight Making good use of other available means is also a very important factor in UV protection.

 

👉 A closing line from an expert

In addition to preventing pigmentation, using sunscreen is also essential for preventing wrinkles. Apply sunscreen thoroughly all year round, not just in summer, to keep your skin healthy and young. I hope you keep it.
