SPF, which is short for “Sun Protection Factor,” means sun protection factor. The SPF rating indicates how much the sunscreen protects the skin against sun rays. Sun protection factors are divided into 3 categories: light, medium, and high.
What SPF Should Sunscreen Be?
Sunscreen SPF should be chosen according to the time spent in the sun and skin type. Generally, SPF 30 or SPF 50 sunscreens are recommended. People with fair and sensitive skin should use high-factor products.
How Long Does Sunscreen Provide Protection?
The duration of sunscreen protection varies depending on the SPF level of the cream used and the activities the person engages in after applying sunscreen. In situations like exposure to water or sweating, more frequent reapplication of sunscreen and the use of waterproof products may be necessary. An SPF 50 sunscreen can provide protection for 3-4 hours.
How Should Sunscreen Be Used?
- Sunscreen should be applied 30 minutes before going outdoors.
- Sunscreen should be applied to the face, ears, and décolleté area and reapplied every 3 hours.
- It should be reapplied after coming out of the water or after sweating.
- Sometimes, using only sunscreen may not be enough. During peak sun hours, it is necessary to avoid prolonged sun exposure, wear hats, and light clothing.
How to Choose the Right Sunscreen for Your Skin Type?
- For oily skin: For oily skin types, a matte-finish sunscreen should be chosen to prevent pore clogging and shine problems.
- For dry skin: For dry skin types, a sunscreen with moisturizing properties should be preferred.
- For sensitive skin: For sensitive skin types, a non-comedogenic sunscreen should be used.

What Should Be Considered When Choosing Sunscreen?
- Skin type: The needs of dry, oily, and sensitive skin types are different. It is not correct to use the same sunscreen for all skin types. A moisturizing sunscreen should be chosen for dry skin, and a matte-finish sunscreen for oily skin.

- Expiration date: Expired sunscreen may lose its effectiveness. Don't forget to check the expiration date when purchasing.
