Skin Protection with SPF and PA to Protect Your Skin from the Sun

Excessive sun exposure can cause various skin problems, including sunburn. To help prevent these effects, using sunscreen with a Sun Protection Factor (SPF) and a Protection Grade of UVA (PA) rating is an important part of your daily skincare routine.

SPF

• Protects the skin against UVB rays, which commonly cause sunburn. The higher the SPF number, the greater the level of UVB protection.

• SPF 15 blocks approximately 93% of UVB rays

• SPF 30 blocks approximately 97% of UVB rays

• SPF 50 blocks approximately 98% of UVB rays

PA

• Protects the skin against UVA rays, which can contribute to premature aging. The more + symbols, the higher the level of UVA protection.

• PA+ Some UVA protection (for primarily indoor use)

• PA++ Moderate UVA protection (for indoor activities)

• PA+++ High UVA protection (for outdoor activities)

• PA++++ Very high UVA protection (for outdoor activities in strong sunlight)

How to Apply Sunscreen Effectively

• Apply approximately two full finger lengths of sunscreen (along your index and middle fingers) to cover your face and neck.

• Apply evenly 15–30 minutes before going outdoors to allow the product to settle and form a protective layer on your skin.

• Sunscreen protection can diminish due to sweating, friction, or facial oils. Therefore, reapply sunscreen every two hours. If you wear makeup, convenient options such as sunscreen sprays or powders can make reapplication easier.

Consult a doctor to choose a product suited to your skin type. Using sunscreen with appropriate SPF and PA ratings is an important step in protecting your skin from sun damage. With the right product and consistent application, you can help maintain healthy, beautiful skin.
