Don't Get Sunburned! The Right Way to Use Sunscreen (Japan's Summer Edition)

Are you applying sunscreen every day? You might think, “Of course, I do!” But are you applying it correctly?
Many people don’t realize that if sunscreen is not applied properly, its effectiveness decreases significantly. That means you might still get sunburned or develop dark spots even though you applied sunscreen!
In this article, we will explain the correct way to use sunscreen, especially in Japan’s unique summer climate.
What Is Japan’s Summer Like?
Japan’s summer is known for being **extremely hot and humid**. If you’re planning to visit Japan, be prepared for a climate that is different from many other countries.
For example, summer temperatures in Tokyo can reach 35°C (95°F) or higher, with humidity levels around 70-80%. Because of this, people sweat a lot, which makes it easy for sunscreen to wear off quickly.
Additionally, Japan experiences very strong UV rays in the summer. From June to August, UV levels peak, and on sunny days, your skin may start to burn in as little as **15 minutes** if unprotected.
Understanding SPF and PA
When choosing sunscreen, you often see SPF and PA on the label. But do you really understand what they mean?
- SPF (Sun Protection Factor) → Protects against UVB rays, which cause sunburn and dark spots.
- PA (Protection Grade of UVA) → Protects against UVA rays, which penetrate deeper into the skin and cause wrinkles and sagging.
Simply put, SPF helps prevent **burning and dark spots**, while PA helps prevent **wrinkles and skin aging**.
How to Apply Sunscreen Correctly in Japan’s Summer
Many people complain that they still get tanned even though they use sunscreen. If this happens to you, you may not be applying it correctly. Let’s check the essential points!
① Apply Sunscreen at the End of Your Skincare Routine
Sunscreen should be applied at the end of your skincare routine. If you wear makeup, apply sunscreen before your foundation.
② Use Enough Sunscreen (About Two Coin-Sized Amounts)
Many people use too little sunscreen. To cover your entire face properly, you need about the amount of two one-yen coins (or two U.S. dime-sized amounts).
③ Spread It Evenly
Dot the sunscreen on your forehead, cheeks, nose, and chin, then gently spread it evenly across your face.
④ Reapply Every 2-3 Hours (Especially Important in Japan!)
Because Japan’s summer is humid and people sweat a lot, reapplying sunscreen frequently is crucial. Ideally, reapply every 2-3 hours.
⑤ Don’t Forget Ears, Neck, and Hands
Areas like the ears, neck, and hands are often forgotten, but they are also exposed to UV rays. Make sure to apply sunscreen there as well!
