It's essential to use sunscreen to protect yourself from the sun's UV rays. Most people believe that sunscreen should only be used when you're outdoors, but the truth is quite different.

Have you ever wondered why your skin starts to tan, hyperpigment, or develop fine lines even when you're indoors? The answer could be not using sunscreen indoors. Let's understand why it's important to apply sunscreen even indoors.

UV Rays Coming Through Windows
There are two main types of sun rays: UVA and UVB.

UVB rays cause skin burns, but they can't penetrate glass. Therefore, you don't get sunburn indoors.

UVA rays are more dangerous because they can easily penetrate clouds and window glass. These rays penetrate deep into the skin and damage collagen.

Therefore, if you sit in a place where light comes in from a window, your skin is constantly exposed to UVA rays. This increases the risk of dark spots and wrinkles.

Digital Screens and Blue Light
These days, we spend most of our time in front of smartphones, laptops, and TV screens. These digital devices emit high-energy visible light, known as blue light. Prolonged exposure to blue light increases oxidative stress in the skin. This stress can cause uneven skin tone and worsen pigmentation. Therefore, it's important to use sunscreen indoors.

How to Choose the Right Sunscreen?
You don't need to use a heavy or sticky sunscreen indoors. You can keep these things in mind:

SPF 30 - Use a sunscreen with at least SPF 30, even for indoor use.

Broad spectrum - Check that your sunscreen protects against both UVA and UVB rays.
Lightweight formula – Gel or lotion-based sunscreens are better for applying at home, as they are lightweight.
