What is Sunscreen Factor?
SPF, an abbreviation for "Sun Protection Factor," indicates how well a sunscreen protects the skin against the sun's rays. Sun protection factors are divided into three categories: light, medium, and high.
How Many SPF Should Sunscreen Be?
The sunscreen factor should be chosen based on the time spent in the sun and your skin type. Generally, SPF 30 or SPF 50 sunscreens are recommended. People with fair and sensitive skin should use high-factor products.
How Many Hours Does Sunscreen Provide Protection?
The duration of sunscreen's protection varies depending on the SPF level of the cream used and the activities a person performs after applying it. In situations like water exposure or sweating, more frequent sunscreen application 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 outside.
- Sunscreen should be applied to the face, ears, and décolletage area and reapplied every 3 hours.
- It should be reapplied after coming out of the water or after sweating.
- Sometimes, just using sunscreen may not be enough. During peak sun hours, it's essential to avoid prolonged sun exposure, wear a hat, and put on light clothing.
How to Choose Sunscreen According to Skin Type?
- For oily skin: For oily skin types, a matte-finish sunscreen should be chosen to prevent clogged pores and shine.
- 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 Do SPF 30 and 50 Factor Mean?
- SPF 50+ sunscreen blocks 98% of UV radiation.
- SPF 30+ sunscreen blocks 96% of UVB rays.
- SPF 15 sunscreen blocks 93% of UVB rays.
- SPF 30 sunscreen blocks 96% of UVB rays.
- SPF 50 sunscreen blocks 98% of UVB rays.
What Does SPF 100 Sunscreen Mean?
For daily use, you should choose a sunscreen with at least 30 SPF. However, if you spend a long time outdoors, you may need to use an SPF 60 or higher sunscreen. SPF 100 sunscreen prevents 99% of UVB rays from reaching your skin. SPF 100 is especially recommended for sensitive skin and those with excessive sun exposure.
What to Consider When Choosing Sunscreen?
- Cilt tipi: Kuru, yağlı ve hassas cilt tiplerinin ihtiyaçları farklıdır. Tüm cilt tipleri için aynı güneş kremini kullanmak doğru olmaz. Kuru ciltler için nemlendirici özelliği olan bir güneş kremi, yağlı ciltler için de mat bitişli bir güneş kremi seçilmelidir.
- Geniş spektrumlu koruma: UVA ışınları cildin yaşlanmasına ve çeşitli cilt sorunlarına yol açabilir. UVB ışınları ise güneş yanıklarına neden olabilir. Cildinizi UVA ve UVB ışınlarından korumak için geniş spektrumlu güneş kremi kullanabilirsiniz.
- Günlük aktiviteler: Güneş ışınları saat 10.00 ile 16.00 arasında daha etkilidir. Bu saatlerde dışarıda olmanız gerekiyorsa yüksek SPF'li bir güneş kremi kullanabilirsiniz.
- Son kullanma tarihi: Son kullanma tarihi geçen güneş kremi etkisini kaybedebilir. Satın alırken son kullanma tarihine bakmayı unutmayın.
