Top 50 Skincare Facts

🧴 General Skincare Facts

1. Your skin is the largest organ of your body, playing a vital role in protection and sensation.

4. A surprising amount—more than 50%—of household dust comes from your dead skin cells.
5. As early as your mid-20s, your body starts to slow down collagen production.
6. Staying hydrated internally can significantly boost your skin’s elasticity and appearance.
7. Ingredients in skincare matter—skin can absorb as much as 60% of what’s applied to it.
8. The skin’s surface maintains a slightly acidic pH, typically between 4.5 to 5.5, to keep harmful bacteria at bay.
9. People with naturally oily skin may develop wrinkles more slowly due to added hydration.
10. Your body sheds approximately 30,000 to 40,000 skin cells every minute.

🌞 Sun & SPF Facts

11. Exposure to UV rays is responsible for up to 90% of premature skin aging.
12. Daily sunscreen use is essential—even on cloudy days or when you’re indoors near windows.
13. UVA rays contribute to aging, while UVB rays cause sunburn—broad-spectrum SPF protects from both.
14. SPF ratings reflect the time your skin is protected before burning compared to unprotected skin.
15. For effective coverage, apply about one teaspoon of sunscreen per area (e.g., face or each arm).
16. There’s no such thing as a “safe” tan—tanning is a form of skin damage.
