Do You Need to Wear Sunscreen Indoors?


Sunscreen or sun protection cream is a skincare product commonly used to protect the skin from the harmful effects of sunlight, including ultraviolet (UV) rays. However, many people wonder if it's necessary to wear sunscreen indoors or at night. This article will discuss whether sunscreen needs to be used indoors and at night.

Do You Need to Wear Sunscreen Indoors?

Even though most of us spend time indoors, UV rays can still damage our skin. UVB rays, which cause sunburn, can be absorbed by glass, and UVA rays, which can lead to wrinkles, freckles, and increased signs of aging, can penetrate windows. Therefore, if you spend a significant amount of time indoors in a sun-exposed area, such as a room with many windows, it is advisable to use sunscreen.

However, if you are in an area with minimal sunlight indoors, such as a windowless room, then the use of sunscreen may not be necessary. However, if you have specific skin concerns, such as melasma or hyperpigmentation, using sunscreen indoors can still help prevent those conditions from worsening.

Do You Need to Wear Sunscreen at Night?

At night, the skin is not exposed to sunlight. Therefore, wearing sunscreen at night may not be necessary. However, some types of sunscreen also have additional benefits, such as moisturizing the skin and protecting it from air pollution, so they can still be used at night.

Additionally, many other skincare products, such as acid peels or retinol, can make the skin more sensitive to sunlight. So, if you use these products, it's recommended to continue using sunscreen during the day and at night to protect your skin.


Sunlight can damage our skin even when we are indoors. Therefore, the use of sunscreen can help protect our skin from harmful UV rays. However, if you have specific skin concerns, such as freckles/melasma or you want to reduce the signs of aging, the use of sunscreen is highly recommended.
