What are the rules for applying sunscreen

Using sunscreen is important to protect your skin from the harmful effects of the sun. Here are some basic rules for using sunscreen.

Choosing the right sun protection factor (SPF): SPF refers to the level of protection against UVB radiation. If you have sensitive or fair skin, it may be advisable to use a higher SPF.

Apply a sufficient amount: Apply sunscreen evenly over all exposed skin. It is recommended to use about 30 ml (approximately two tablespoons) of sunscreen on the whole body.

Apply before exposure to the sun: Sunscreen should be applied approximately 15-30 minutes before sun exposure to give it time to absorb and provide protection.

Re-apply regularly: sunscreen should be re-applied every 2 hours, or after swimming, sweating or toweling, which may reduce its effectiveness.

Don't forget sensitive areas: Some parts of the body, such as the face, ears, neck, hands and feet, are particularly susceptible to sunburn. Be sure to apply enough sunscreen to these areas.

Use in the shade: Even if you are in the shade, it is still possible to be exposed to harmful UV rays. That's why it's important to use sunscreen even when in the shade.

Combine with other protective measures: The use of sunscreen should be supplemented with other protective measures such as wearing protective clothing, a wide-brimmed hat and sunglasses, avoiding direct sunlight during the most intense hours (usually from 10:00 a.m. to 4:00 p.m.)

Keep sunscreen in a tightly sealed bottle: Protect sunscreen from direct sunlight and keep it in a cool, dry environment. High temperatures can affect its effectiveness.

Check the expiry date: Sunscreen has a limited shelf life. Check the expiration date regularly and do not use a sunscreen that is past its expiration date.

Use sunscreen even in winter: Sunlight can be harmful even in the winter months, especially in the mountains or in areas with strong reflection of sunlight. Wear sunscreen even during winter outdoor activities.

Special precaution for children: it is important for children to use special sunscreens with appropriate protection for their sensitive skin. Children should also wear protective clothing, hats and sunglasses.

Consult a doctor: If you have sensitive skin, allergies or other health problems, you should consult a doctor about the most suitable sunscreen and how to use it.

It is important to remember that using sunscreen is not the only measure you should take to protect yourself from the sun. Following other precautions, such as wearing appropriate clothing and avoiding direct sunlight during the most intense hours, is also essential to protect your skin.
