Apply sunscreen correctly to prevent UV rays! Explains tips and precautions to apply for each part

Many people use sunscreen to prevent dark spots and dullness. Sunscreen is an item that can reduce the burden on the skin by blocking UV rays, but if it is not applied correctly, it will be less effective. However, there are many people who do not know how to apply it correctly. Therefore, this time, I will explain in an easy-to-understand manner the correct way to apply sunscreen, tips, and precautions.

Get the basics before you know how to apply sunscreen correctly. There are two things to keep in mind about sunscreen:

Difference between SPF and PA

“SPF” and “PA” are always set for sunscreen. SPF describes how long the effects of “UVB”, which causes skin irritation and darkening in a short period of time, can be prolonged. The higher the number, the higher the effect of preventing UVB.

PA has the effect of preventing “UVA” that penetrates deep into the skin and denatures or destroys the elasticity of the skin. The greater the number of “+”, the more effective it is in preventing UVA. It is important to choose a sunscreen with appropriate SPF and PA values ​​according to the time you go out and the intensity of UV rays.

Use SPF20-30, PA ++-+++ for everyday use, SPF30-50, PA +++ for outdoor leisure, SPF40-50, PA ++++-for marine sports under the scorching sun.

Types of sunscreen

There are many types of sunscreens, including creams, gels, milks and sprays. Let’s take a closer look at each feature.

Cream ・ ・ ・ Some
gels have high moisturizing power and high water resistance Gel ・ ・ ・
Milk that is not sticky with a fresh feeling of use
・ ・ ・Recommended for sensitive skin because many of them are gentle on the skin No need to apply, refreshing feeling In

this way, the feeling of use and the gentleness to the skin differ depending on the sunscreen.

When applied correctly, sunscreen will have a UV protection effect. Let’s take a closer look from the basics of how to apply to how to apply each part.

About the basics of painting

Apply sunscreen evenly so that it is even. When spreading, it is important to apply while moving your hands a lot. Applying a large amount of sunscreen does not increase the effect, so be sure to use it.

How to apply face and neck

Apply sunscreen to your face and neck as follows:

(1) Take an appropriate amount and place it on both cheeks, chin, nose and forehead.
(2) Use your fingers or palm to spread the sunscreen from the center of the face to the outside.
(3) Put sunscreen on several places on your neck and stretch it firmly.
(4) Apply it over the nose and chin, which are easily exposed to ultraviolet rays.

It is important to stretch it firmly until the sunscreen is transparent.

How to apply to the body

Here’s how to apply sunscreen to your body:

(1) For each part, take the amount of pearl grains for the cream type and the amount of 100 yen coins for the lotion type.
(2) For the tube type, place it linearly on the skin directly from the container.
(3) Spread it with your palm or fingers so that it fits the entire skin.

You want to apply sunscreen to your back, shoulders, calves, thighs, knees, ankles, feet, arms, and elbows. UV rays hit the whole body and everywhere, so spread it well. If it gets slow, add sunscreen instead of forcing it.

Also, if you apply a lotion or milky lotion and then apply sunscreen, it will spread better.

In order to get the best effect of sunscreen, check the following two points.

About unpainted

There is no UV protection on the unpainted areas, so the risk of stains and dullness remains high. Please note that the following parts are easy to leave unpainted.

・ Hairline If
you are concerned about stickiness when it gets on your hair, apply lotion-type sunscreen.

・
Be careful not to apply too much because the ear area is small.

・
Apply firmly to the point where there is a step on the nose .

・ Face line If
you apply it so that it extends from your cheeks to your neck, it will be difficult to leave it unapplied.

・
It is important to apply it carefully because the back of the hand is exposed to sunlight.

・ Knees and back of knees It is
recommended to apply on the entire legs and then separately on the knees and the back of the knees .

・ Back
If possible, have another person apply your back. Even if you reach your back, you will not be able to spread it firmly. It will be difficult to check if it is uneven. Depending on the fabric of your clothes, UV rays can pass through your clothes even if your back is hidden by the clothes, so it is important to apply sufficient sunscreen.

Apply sunscreen to all areas exposed to UV rays. You may also get sunburned by the reflection from the ground. It is important to apply it firmly to the point where it is unlikely to be exposed to ultraviolet rays.

How and timing to repaint

No matter how large your sunscreen SPF is, it’s important to reapply it once every two to three hours. Sunscreen can easily be washed away by sweat. If the sunscreen itself is washed away, the effect of blocking UV rays will be lost no matter how high the SPF value is.

When you go to the pool or the sea, it will be washed away with water. Even if you are using a highly water resistant sunscreen, reapply it once every 2-3 hours.

When reapplying, use a towel to thoroughly remove the moisture on your skin. If there is moisture, the sunscreen will not stick to your skin and will flow quickly.
