Physical vs. Chemical Sunscreens
Summertime is here, and with so many family-friendly outdoor activities available, it’s time to protect yourself and your family against potential sun damage.
Sunscreen is usually the first line of defense when it comes to sun protection, but with so many options, which should you use?
Physical sunscreens (sometimes referred to as inorganic sunscreens) use physical UV filters and protect your skin by deflecting or blocking the sun’s rays.
- Physical sunscreens don’t wear off as quickly so they can last longer than chemical sunscreens.
- They start to work immediately and generally do not require as much (if any) re-application as chemical ones.
- Physical sunscreens are a bit thicker, so they tend to leave a white streak after application (kind of like when lifeguards apply them to their noses).
- They feel a bit greasy after application.
Chemical sunscreens (or organic sunscreens) use chemical UV filters and protect your skin by absorbing the sun’s rays.
- Chemical sunscreens generally offer more coverage against UVA and UVB rays.
- They’re usually colorless and odorless, unlike physical sunscreens.
- Chemical sunscreens can take up to 20 minutes before they’re effective, and they must be re-applied more often.
- Some chemical ingredients produce free radicals, which can cause skin damage, irritation and aging.
Most dermatologists recommend sunscreens with SPF 30 for the average person, as those with a higher SPF do not provide a significant increase in protection.
