How thick should you apply sunscreen? Outdoor swimming is different

Sunscreen has always been a problem. Many people don’t know how thick to apply it. If you apply too little, it will not be effective. If you apply too much, it will affect the skin’s breathing. What can you do? How thick should you apply sunscreen?

Sunscreen has always been a problem. Many people are confused when applying sunscreen. How much should they apply? Is it true that the more you apply, the better? Applying too little will not improve your beauty, but applying too much will make your skin unable to breathe. So how much sunscreen should you apply?

How thick should you apply sunscreen?

1. Generally speaking, the amount used is more than that of face cream, at least the size of a one-yuan coin. A 30 ml bottle of sunscreen should be used up in more than a month in summer. The general application amount is 2 mg per square centimeter. 2-2.5 grams should be applied to a pair of arms at a time, and 1-1.5 grams is generally sufficient for the face at a time.

2. Sunscreen is divided into physical sunscreen and chemical sunscreen. The molecules of physical sunscreen are relatively large. Excessive rubbing will squeeze them into the pores, causing the pores to be clogged, which will reduce the sun protection effect. The correct way to apply it is to pat it gently with your hands and spread it evenly on the parts that need sun protection;

3. Chemical sunscreen is different. It needs to be absorbed before it works. You can apply sunscreen to different parts of your body, then spread it evenly with your fingertips, and then apply it evenly in large circles. Finally, apply it to the tip of your nose, which is prone to sunburn.

4. Apply sunscreen daily. You can apply sunscreen with moisturizing and whitening effects, mainly light cream; when traveling outdoors or going to the beach, it is easy to sweat in the hot summer, and swimming at the beach will cause the skin to come into contact with water, so it is best to choose sunscreen that is water-resistant and sweat-resistant.

5. Sunlight contains UVB and UVA: UVB tans the skin and UVA ages the skin. SPF fights against UVB and prevents suntan. SPF1 = 10 minutes of sun protection time, and SPF30 on sunscreen equals 5 hours of sun protection time. PA fights against UVA and prevents skin aging. The "+" represents the index of sunscreen products in delaying UVA damage. The more "+"s are indicated on the bottle, the stronger the anti-aging ability is.

This is the explanation about how much sunscreen to apply. There is really no standard for how much to apply, so it still depends on your own comfort level.

Do I need to use sunscreen every day?

It is recommended to apply it every day.

Because ultraviolet rays are everywhere in life, especially those who work outdoors for a long time are more likely to be exposed to ultraviolet rays than those who work indoors. You may not feel anything if you don’t apply sunscreen once, but sun exposure is cumulative. If you don’t apply sunscreen for a long time, your skin will get tanned, develop spots, wrinkles, etc., and in severe cases it may even lead to skin cancer.
