Frequently Asked Questions

1.

What are the consequences of neglecting daily sunscreen application for my skin?

Neglecting daily sunscreen application can lead to skin darkening and increased susceptibility to damage from UV radiation. This can result in long-term skin issues, including premature aging and skin cancer.
2.

Is it sufficient to apply sunscreen only on my face for complete sun protection?

No, applying sunscreen only on your face is not sufficient. UV rays can penetrate clothing and glass, affecting areas of the body not covered by sunscreen. It's essential to apply sunscreen to all exposed skin.
3.

How much sunscreen should I apply to ensure optimal skin protection?

For optimal protection, apply 2 milligrams of sunscreen per square centimeter of skin. This averages to about 1.2 grams for the face and 25 to 30 grams for the body, ensuring full coverage.
4.

Why is it necessary to reapply sunscreen every few hours during sun exposure?

Sunscreen needs reapplication every 2 to 3 hours because its effectiveness diminishes over time. Each SPF unit provides about 10 minutes of protection, so frequent reapplication ensures continuous defense against UV rays.
