Deciding which sunscreen is ideal for you? Continue reading to learn about the difference between chemical and physical sunscreen. 

Sunscreens are well known to be an essential component of any skincare regimen. Put on some sunscreen, whether you’re sixteen or sixty, to avoid the aging effects of sun damage. However, did you realize there are several kinds of sunscreens? And no, the SPF is not on the table. Physical and chemical sunscreens can be generally categorized as sunscreens. Here is all the information you require about them.

Importance of applying sunscreen daily

The simplest way to explain the significance of sunscreen is to say that it shields your skin from the sun. UV (ultraviolet) rays, a type of natural energy the sun produces, can harm the skin. There are two kinds of UV radiation that can harm people in various ways:

  • UVA radiation, which has been linked to early skin aging
  • UVB — a type of ultraviolet light that causes sunburns

 Your outer layer of skin is composed of cells containing melanin, a pigment that protects your skin from the sun. Melanin, however, has a limited capacity; too much ultraviolet exposure damages these cells. 

Sunscreen shields your skin from UV damage and helps to keep it healthy. This damage could demonstrate as:

  • Sunburns that are intense or frequent.
  • Pop in your skin’s blood vessels
  • Age-related wrinkles in the skin
  • Skin Cancer

What is SPF?

The SPF level is denoted by a number on the bottles of sunscreen (typically 15, 30, 50, and so on). SPF stands for Sun Protection Factor, and the value indicates how long sunscreen application will prevent sunburn on your skin. A sunscreen with SPF 30 will protect your skin for 30 times longer than one without. 

Although you are technically protected for a specific time, it is typically advisable to reapply your sunscreen every two hours. 

What are physical sunscreens?

Physical sunscreens often sit on the skin and refract the sun’s rays, the most evident distinction between the two types of sunscreens. The physical sunscreens are typically creamy and frequently have a white cast since they are made of tiny particles of minerals like zinc oxide and titanium dioxide. Physical sunscreens’ thick consistency makes it simple to detect their presence on the skin, allowing you to apply them evenly. 

What are chemical sunscreens?

Most sunscreens seen on beauty aisles and suggested by dermatologists fall into this group. They take in ultraviolet light, transform them into heat, and then expel the heat from the body. Avobenzone, octinoxate, and oxybenzone are examples of active chemicals found in chemical sunscreens because of their gel-like nature. Chemical sunscreen offers efficient protection without the need for heavy application. It is appropriate for any day and season because it is lightweight and non-sticky. It is also effective against UVA and UVB radiation, which results in early aging.

When should you apply the sunscreen?

No matter what sequence you apply your skincare products, as long as the sunscreen is broad-spectrum, water-resistant, and at least SPF 30, it doesn’t matter. Some people discover that working with bare skin, without moisturizer or makeup, is the simplest. Find the solution that best suits your routine. Ask your dermatologist if you have any questions regarding layering particular products.

Do you need to reapply sunscreen?

In general, you need to reapply the sunscreen every two hours. You may not need a second application if you work indoors and sit away from windows. But be careful how often you go outside. To be cautious, keep a spare bottle of sunscreen at your workplace. Even a brief lunchtime stroll could be detrimental to your skin.
