When it comes to sun protection, the variety of products on the market may make you question which formula is the right one for you.
You might have heard about chemical sunscreens and physical sunscreens, but what are the differences that set them apart?
Continue reading about the qualities of each product to find which formula is ideal for your skin type and lifestyle.
Chemical Sunscreen
Chemical sunscreens work by absorbing UV radiation and converting it into heat that's released from the skin.
When you apply a chemical sunscreen, it penetrates the top layer of your skin. The products are composed of organic compounds that create a chemical reaction to protect your skin from the sun's harmful rays.
Ingredients
Chemical sunscreens include ingredients such as oxybenzone, avobenzone, octisalate, octocrylene, and octinoxate. Each of these ingredients has unique properties that protect against different types of UV radiation.
- Oxybenzone absorbs UVB and UVA rays for broad-spectrum protection.
- Avobenzone is effective against the entire UVA spectrum to prevent skin damage and aging.
- Octisalate enhances the stability of other sunscreen components and helps absorb UVB rays.
- Octocrylene protects against UVB rays and stabilizes other ingredients so that they don't break down.
- Octinoxate provides UVB protection.
Pros and Cons
Chemical sunscreens blend seamlessly into the skin and do not leave a white cast. They are also water-resistant, making them ideal for swimming or sweating.
However, some people with sensitive skin may experience irritation or have allergic reactions to the ingredients.
Physical Sunscreen
Physical or mineral sunscreens protect your skin by reflecting UV rays away from the surface of the skin. They don't absorb into the skin. Instead, they sit on the surface to form a physical shield that scatters UV radiation.
Ingredients
The primary ingredients in physical sunscreens are zinc oxide and titanium dioxide. These minerals provide broad-spectrum protection by blocking both UVA and UVB rays.
Zinc oxide is ideal for those with sensitive skin because of its non-irritating properties. Nonetheless, titanium dioxide is also gentle and effective.
Pros and Cons
Physical sunscreens are less likely to cause skin irritation and are generally considered safer for those with sensitive skin and children.
The downside of the formula is it can leave a white cast on the skin. Plus, it might feel heavier or greasier on the skin when compared to chemical sunscreens.
Tips for Applying Sunscreen
It might seem obvious how to apply sunscreen. Nevertheless, there are a few techniques to note for adequate skin protection.
1. Chemical Sunscreen Needs Time To Absorb
Smooth chemical sunscreen on your skin 15 minutes before going outside. Since it works best once absorbed, you need the extra time to receive the benefits.
2. Apply Mineral Sunscreen Last
Learning when to apply sunscreen in your skincare routine is just as important as the type you choose. Mineral sunscreen works best when it’s applied last in your routine. It forms the final barrier you need for ultimate protection.
3. Reapply Sunscreen Throughout the Day
One of the differences between chemical and physical sunscreen is that chemical sunscreen is more water-resistant. If you’re sweating or swimming, chemical sunscreen will last for longer. Reapply this type of sunscreen every two hours.
Physical sunscreen, on the other hand, is more likely to wear off if it comes into contact with sweat or water. In this case, reapply it every hour to safeguard your skin.
