How to Choose The Perfect Sunscreen

There are various types of radiation in sunlight; the well-known one is ultraviolet (UV) radiation, which is absorbed by the ozone layer. There are two types that reach the Earth's surface: UVA and UVB. These two types of radiation have different effects on the skin. UVA contributes to the formation of freckles, age spots, and wrinkles, while UVB causes redness, burning, and skin damage. Both types of radiation also generate free radicals that can damage genetic proteins and lead to skin cancer. However, there's no need to worry because here are some tips for choosing sunscreen cream for your lifestyle.

1. SPF (Sun Protection Factor) indicates how well the product protects against UVB radiation, but there is no standardized measure for UVA protection yet. Currently, it is common to use the PA rating system along with the "+" sign. Considering that Thai people generally have dark skin that offers some natural UVB protection, an SPF of 15 or higher and PA++ is sufficient.

2. Consider your activities. If you engage in outdoor activities such as exercising, swimming, or working under the sun, you should choose a higher SPF and opt for a water-resistant or waterproof sunscreen.

3. Use an adequate amount of sunscreen. Using too little may reduce its effectiveness due to chemical reactions.

4. The frequency of application is important. If you work indoors in an air-conditioned environment, applying once a day is sufficient. However, if you work under the sun or are exposed to wind and water while swimming, reapply every 2-3 hours.

5. After applying sunscreen, it is important to avoid direct sunlight. Wear sunglasses and a hat since sunscreen cannot provide 100% protection.

6. Brand and price are not crucial. Focus on finding a sunscreen with all the necessary qualities and no adverse effects on the skin, such as itching or rashes.

7. Don't forget about nutrition. Consume foods rich in antioxidants, such as vitamins and minerals found in various vegetables and fruits. These nutrients help combat free radicals.

Once you learn how to choose sunscreen that suits your daily activities, you can confidently protect your beautiful skin from the sun's rays.
