Summer is just around the corner, and with it comes the need to protect our skin from the harmful effects of the sun. Ultraviolet (UV) radiation from the sun can cause skin damage, including sunburn, premature aging, and even skin cancer. That's where sunscreen comes in. In this post, we'll explore how zinc sunscreen works to protect against UV rays, and why it's a better choice for both your health and the environment.
What is Zinc Sunscreen?
Zinc sunscreen, also known as mineral sunscreen, is a type of sunscreen that uses zinc oxide as its active ingredient. Zinc oxide is a naturally occurring mineral that provides a physical barrier between your skin and the sun's UV rays.
When you apply zinc sunscreen, it sits on top of your skin and reflects and absorbs UV rays away, rather than only absorbing them like chemical sunscreens.
How Does Zinc Sunscreen Protect Against UV Rays?
Zinc sunscreen works by creating a physical barrier on top of your skin. The zinc oxide particles in the sunscreen mostly reflect the UV rays away from your skin, so they don't penetrate and cause damage.
This is different from chemical sunscreens, which work by absorbing the UV rays and converting them into heat, which is then released from the skin.
Zinc sunscreen offers broad-spectrum protection, meaning it protects against both UVA and UVB rays. UVA rays are the ones that cause premature aging, while UVB rays are responsible for sunburn. By using a broad-spectrum sunscreen, you're protecting your skin from both types of damage.
Why is Zinc Sunscreen Better for Your Health?
Zinc sunscreen is a safer choice for your health than chemical sunscreens. Chemical sunscreens contain ingredients like oxybenzone and avobenzone, which have been shown to disrupt hormone systems and contribute to coral reef destruction.
Zinc oxide, on the other hand, is a natural mineral that has been used for centuries in traditional medicine. It's gentle on the skin and doesn't cause irritation or allergic reactions like some chemical sunscreens can.
Additionally, zinc sunscreen provides immediate protection upon application, whereas chemical sunscreens need to be applied at least 20 minutes before sun exposure to be effective. This means you don't have to worry about getting burned while waiting for your sunscreen to start working.
Is Zinc Sunscreen Environmentally Friendly?
Yes! Zinc sunscreen is a more environmentally friendly choice than chemical sunscreens. Chemical sunscreens have been shown to contribute to coral reef destruction, as the chemicals can bleach and kill coral reefs. In fact, Hawaii has banned the sale of sunscreens containing oxybenzone and octinoxate in an effort to protect its coral reefs.
Non nano zinc oxide is a mineral that doesn't harm coral reefs. Zinc sunscreen is also biodegradable and doesn't contain harmful chemicals that can leach into the environment.
How to Choose the Right Zinc Sunscreen?
When choosing a zinc sunscreen, look for one that is labeled "broad-spectrum" to ensure it protects against both UVA and UVB rays. You should also look for a sunscreen with an SPF (sun protection factor) of at least 30. It is essential you read the ingredients list and know what you are putting on your skin. Check to see if the zinc sunscreen you’re considering has at least 20% non-nano zinc oxide as it’s only Active Ingredient.
Zinc sunscreen can come in a variety of forms, including lotions, pastes, creams, and sticks. Choose the one that works best for your needs and preferences. Some zinc sunscreens can leave a white cast on the skin, but there are now many options that are tinted and blend into the skin seamlessly.
