Are Physical Sunscreens Effective? The What and Why
Physical sunscreens are also known as mineral sunscreens are becoming increasingly popular among skincare enthusiasts. These sunscreens work by physically blocking the sun's harmful ultraviolet (UV) rays. In contrast, chemical sunscreens contain ingredients to absorb them.
Here are some of the benefits of using physical sunscreens:
1. Physical sunscreens are generally considered to be safer for the skin than chemical sunscreens. Chemical sunscreens can contain a range of potentially harmful ingredients, including oxybenzone, avobenzone, and octinoxate - that have been linked to skin irritation, hormone disruption, and even cancer. Physical sunscreens typically use natural minerals like zinc oxide and titanium dioxide to block UV rays, making them a safer option. These ingredients are also less irritating for those with sensitive skin or allergies.
2. Physical sunscreens are effective immediately upon application. Chemical sunscreens need to be applied 20-30 minutes before sun exposure in order to be fully effective. This is inconvenient for people in a hurry, and those who forget to apply sunscreen until they're out in the sun. With physical sunscreen, you can simply apply it and go. Your skin is protected right away.
3. Physical sunscreens don't contain the chemical ingredients that can be irritating to eyes. Physical sunscreens a great option for people who are active outdoors, or who spend a lot of time in the water, where chemical sunscreens can easily run into the eyes and cause discomfort.
4. Physical sunscreens are better for the environment versus chemical sunscreens. The ingredients in chemical sunscreens have been found in high concentrations in the ocean and can be harmful to marine life. In contrast, the minerals used in physical sunscreens are not harmful to marine life, and are biodegradable. Physical sunscreens are reef-safe.
Physical sunscreens offer a number of benefits over chemical sunscreens. They are safer for the skin, effective immediately upon application, less likely to cause irritation or stinging in the eyes, and better for the environment. For these reasons, many people are choosing to switch to physical sunscreens to protect their skin from the sun's harmful UV rays.
