What is the Best Sunscreen?
The one you will use!
It is best if it has the following:
- Broad-spectrum: UVA and UVB protection
- SPF 30 or greater
What does SPF mean?
Sun Protective Factor (SPF). An SPF of 30 means it will take you 30 times longer to develop a sunburn than if you did not use sunscreen.
There are 2 types of sunscreen
- Physical Sunscreen
- Active ingredients: zinc oxide and titanium dioxide
- This sunscreen creates a protective barrier between your skin and the sun
- Chemical Sunscreen
- Active ingredients: oxybenzone, avobenzone, octisalate, octocrylene, homosalate, and octinoxate
- These chemicals absorb the sun’s harmful UV rays
The “chemical” sunscreens are “UV organic filters” and the “Physical” sunscreens are inorganic mineral compounds.
Why is it important to have broad-spectrum sunscreen?
- UVB causes sunburns
- UVA causes premature aging
- Both contribute to skin cancer
- The best sunscreen is the one you will use!
- Sunscreen can prevent premature aging such as wrinkles and age spots
- SPF 30 blocks 97% of the sun’s UVB rays
- Creams and lotions are good choices for the face
- Gels and sprays are good for hairy areas such as the scalp
- You should reapply sunscreen every 2 hours
- Do not forget to apply sunscreen to your lips, tops of your ears, and to your scalp
- On overcast cloudy days 80% of the sun’s ultraviolet radiation reaches your skin.
