Chemical Vs. Physical (Mineral) Sunscreen
You
need daily sun protection to keep your skin healthy and youthful. But,
which type of sunscreen should you choose?
Sun protection generally
falls into one of two categories: chemical and physical (mineral).
Sunscreen is essential to keep skin protected from the dangers of sun exposure, including sunburn, sun damage and melanoma. It's also beneficial in minimizing the aging effects of UV rays, such as fine lines and wrinkles, rough skin and hyper-pigmentation.
The
two categories of sunscreen are chemical and physical. While both
provide protection, chemical sunscreen and physical sunscreen differ in
their active ingredients as well as the way they protect against UV
exposure. Here, we've compiled the key points you need to know about
each type.
Chemical Sunscreen
Chemical
sunscreens are often referred to as 'absorbers'. Their active
ingredients are organic (carbon-based) compounds that absorb UV rays.
Through a chemical reaction, these compounds convert UV rays into heat,
then release that heat from the skin.
Physical Sunscreen
Physical sunscreens are "reflectors." Their active ingredients include zinc oxide and titanium dioxide, which act as physical blockers. These minerals form a protective barrier on the skin and reflect harmful UV rays before they make contact with the skin's surface.
Mineral Sunscreen Benefits
If you aren't yet convinced by zinc's superpowers, here are a few more reasons to add a mineral sunscreen to your daily routine.
Suitable For All Skin Types
Mineral sunscreens are hypoallergenic and non-comedogenic. With their anti-inflammatory properties, they are gentle enough for the most sensitive skin types. And, they are free of pore-clogging silicons, making them a better option for those prone to blemishes.
Reef-Safe
Mineral sunscreens are also reef-safe; zinc oxide and titanium dioxide do not pose a threat to our planet's delicate coral reefs. They are an ideal, environmentally-friendly choice for beach-goers and destination travelers who visit ocean side resorts.
Broad Spectrum Protection
Mineral sunscreens reflect both UVB and UVA rays from the skin's surface. UVB rays cause sunburn and uncomfortable symptoms such as redness, dryness and itchiness. UVA rays, which penetrate the skin more deeply, are responsible for premature aging and play a key role in the development of melanoma.
