I think many people think that it is only necessary to take measures against UV rays in the summer. In fact, UV rays are shining all year round, so it’s important to take UV care when you go out. You are wondering what kind of UV care is effective for UV protection. Therefore, this time, we will introduce in detail from the basic knowledge of UV care to how to use sunscreen.

What is UV care? Basic knowledge of UV care

First, let’s look at the basic knowledge of UV care.

What is UV care?

UV care is skin care that protects the skin from UV rays. UV rays are shining even in seasons other than summer when the sun is strong, so be sure to take UV care when you go out. Ultraviolet rays adversely affect the firmness components such as collagen and elastin deep in the skin, causing sagging and wrinkles.

In addition, excessive production of melanin pigment can cause stains.

UV care basics

The basics of UV care are the following two.

Apply sunscreen

Sunscreen creams and oils are items that protect the skin by absorbing and scattering ultraviolet rays. Apply sunscreen not only to the exposed areas, but also to the areas hidden by your clothes.

Use a parasol and hat

Putting on a UV-blocking parasol or wearing a hat is also useful for UV care. UV rays pass through the fibers, so be sure to choose UV-blocking ones.

When choosing sunscreen, keep an eye on SPF and PA values. Here’s how to choose the right sunscreen.

Difference between SPF and PA

Let’s take a closer look at sunscreen SPF and PA.


It shows how long the effects of UVB, which causes inflammation on the surface of the skin, can be prolonged. It takes 15 to 20 minutes for the effects of UVB to appear on the skin. Therefore, by multiplying the SPF value by 15 to 20, you can see how much time it takes for the skin to be affected.

For example, in the case of SPF30, SPF30 x 15 to 20 minutes = 450 to 600 minutes.


PA has an effect on UVA that penetrates deep into the skin and adversely affects collagen and elastin. The greater the number of “+” s in the PA, the better the ability to prevent UVA.

How to choose sunscreen

There are various types of sunscreens, such as gel type, emulsion type, and waterproof type, as well as SPA and PA values. We will introduce how to choose sunscreen by dividing it into three categories: scene, comfort, and function.

[By scene] Sunscreen that you want to recommend

Choose a sunscreen for each scene, such as daily shopping or sports under the scorching sun. SPF10 ~ 30, PA + ~ ++ for daily walks and shopping, SPF10 ~ 30, PA ++ ~ +++ for outdoor light sports and leisure, SPF30 ~ 50, PA +++ ~ for marine sports and leisure under the scorching sun ++++ is recommended.

[By comfort] Sunscreen that you want to recommend

Use the gel type if you want a silky feel, and the emulsion type if you want to moisturize and oil your skin.

[By function] Sunscreen that you want to recommend

If you go to the sea or pool, we recommend waterproofing that is hard to remove even if it gets wet, and if you want whitening care at the same time, we recommend sunscreen containing whitening ingredients. Sunscreen is washed away by water and sweat, so you’ll want to actively choose a waterproof type.

Does it have no effect if not applied properly? Is the sunscreen properly applied?

Sunscreen can only be effective if used correctly. Let’s bring out the effect of sunscreen by holding down the following points.

Take enough to feel a little more

Sunscreen is not effective unless you apply a sufficient amount, so take a large amount. The required amount varies depending on the area to be applied, so apply it several times and check the appropriate amount.

Apply evenly to face and body

It is important to apply sunscreen evenly to your face and body. If there is unevenness, spots may appear on the thinly applied area, and slack or wrinkles may easily occur. The back is hard to reach, so ask your friends, family, or partners to apply it.

Also, when applying to the face, place sunscreen on both cheeks, forehead, nose, and chin and apply in a circular motion. At this time, if you apply it so that it wraps around your face, it will not be uneven.

Carefully apply the ears, neckline, back, and chest, which are often forgotten.

Carefully apply to the ears, the back of the neck, the back, and the chest. Ultraviolet rays affect the whole body by reflecting on the ground. Therefore, it is important to apply sunscreen to areas that do not seem to need to be applied.

Reapply once every 2-3 hours

Sunscreen is sweaty, so reapply it once every 2-3 hours. No matter how large the SPF value is, the UV blocking effect will be lost if it is washed away by sweat. It is easy to sweat in the summer, so it may be necessary to reapply it more frequently depending on the situation.

Keep the specified amount and apply it (do not stingy)

If you apply only a small amount just because you want to save sunscreen, you will not get the full effect. On the contrary, sunscreen is wasted, so it is important to apply the prescribed amount.

Also, if you don’t want to apply sunscreen because it’s sticky, choose the smooth type.

Get in the habit of applying sunscreen regardless of the weather

Speaking of sunscreen, many people think that they only need to wear it on days with strong sunlight. UV rays are shining even on cloudy and rainy days, so it is important not to miss UV care every day.

By not missing daily UV care, you will be able to prevent forgetting to apply.


It is important to start UV care as a teenager. Now, even if you don’t have spots, sagging, or wrinkles, skin problems start to stand out in your 30s and 40s. Also, the wrong UV care doesn’t block enough UV rays, so learn the right way. Regardless of the weather or season, take UV care every day to keep your skin free of blemishes and sagging.
