Serious Question – Should You Wear Sunscreen Indoors?

Published : July 2, 2021 10 mins read Updated On : May 03, 2023

The issue of whether or not sunscreen should be worn indoors has come up for discussion as people become more aware of how important sun protection is. Sunscreens or sunblocks have typically been connected to outdoor pursuits like going to the beach or playing sports. However, the need for indoor sun protection has drawn more attention as people spend more time indoors, particularly with the advent of remote work and spending more time at home due to lifestyle changes. This blog post will explore this important topic and examine why using sunscreen inside might be helpful.

What happens when you apply sunscreen indoors?

Sunscreen functions as a barrier on your skin to block or reflect ultraviolet (UV) light from the sun when applied indoors. Because less UV light reaches your skin indoors than outside, sunscreen's effectiveness may be lessened. However, because windows and walls shield most UVB (shortwave) and some UVA (longwave) rays, indoor UV radiation exposure is substantially less intense than outdoor UV radiation exposure.

Since most sunscreens are designed mainly for outdoor use, using them indoors may be optional or as effective. Nonetheless, wearing sunscreen to protect your skin from potential UV exposure may be advantageous if you spend extended periods close to windows with direct sunlight or use artificial sources of UV radiation indoors, such as tanning beds. Also, specific contemporary windows are made to let a certain amount of UV radiation through, so it's still feasible to get some UV exposure indoors.

Not all sunscreens are created equal, and their efficacy might change based on things like the SPF (sun protection factor) rating, the kind of UV radiation being blocked (UVA or UVB), and the sunscreen's formulation. Hence, whether you're inside or outside, it's essential to pick a broad-spectrum sunscreen with a high SPF and apply it as instructed by the manufacturer for the best protection. The use of protective clothes, searching out shade, and limiting screen time are other ways to reduce indoor UV exposure and safeguard your skin from potential harm.

Do You Need a Full Spectrum Sunscreen Indoors?

A full-spectrum sunscreen, commonly called a broad-spectrum sunscreen, offers protection against UVA and UVB rays. In contrast to UVB radiation, which predominantly affects the skin's outer layer and is linked to sunburns, UVA radiation has a longer wavelength and can penetrate deeper into the skin. UVA radiation also causes the skin to age. UVA and UVB radiation can harm the skin and raise the risk of skin cancer.

While UV exposure from the sun indoors is often less potent than outside UV radiation, skin damage can develop over time. For instance, continuous exposure to artificial light sources like computer screens, LED lights, and fluorescent lights can cause fine lines, wrinkles, and pigmentation changes in the skin. Also, although the risk is typically lower compared to outdoor UV exposure, certain studies have revealed that indoor UV radiation may also contribute to developing skin cancer.

Using a broad-spectrum sunscreen indoors can lessen the risk of skin damage by shielding your skin from UVA and UVB radiation. Suppose you spend much time indoors or are exposed to strong artificial light sources. In that case, applying sunscreen liberally to all exposed skin regions is crucial and reapply it as the manufacturer instructs. Your skin's defence against indoor UV radiation can also be improved by combining sunscreen with other sun safety practices, including seeking shade, using protective clothing, and minimising screen time.

Do You Need To reapply Sunscreen Every Couple of Hours?

Well, it's usually advised to reapply sunscreen every couple of hours, especially if you're outside and in the sun. This is because elements including sweat, water, friction from clothing or a towel, and sun exposure can cause sunscreen to wear off or lose its effectiveness over time. Reapplying sunscreen ensures sustained protection against damaging UV radiation while preserving its efficacy.

Many elements, including the sunscreen's SPF (sun protection factor), the quantity of sunlight exposure, the amount of physical activity or sweat, and whether you have wiped or touched your skin, might affect how often you should reapply sunscreen. Reapplying sunscreen usually is advised every two hours, as well as away after swimming or sweating profusely and right after towel drying.

For optimum use, it's crucial to adhere to the manufacturer's directions since certain sunscreens may have varying suggestions for reapplication. Although some sunscreens may make claims of being "water-resistant", "acne-prone skin sunscreen", or "sweat-resistant," meaning they might offer more prolonged protection, it's still crucial to reapply sunscreen frequently for the most excellent benefits.

Remember that sunscreen should be one step in your total sun protection routine. To further shield your skin from damaging UV rays, it's also vital to seek out shade, wear protective gear like hats and sunglasses, and limit your time in the sun during peak hours. Now the question arises what type of sunscreen to use, chemical or mineral?

Chemical Sunscreen vs Mineral Sunscreen

Chemical and mineral sunscreens are two distinct forms of sunscreens that shield the skin from the damaging effects of UV radiation in different ways.

Chemical Sunscreens: Chemical sunscreens are composed of organic (carbon-based) substances that absorb ultraviolet (UV) radiation and transform it into heat expelled from the skin. Avobenzone, oxybenzone, octinoxate, and other organic chemicals, which absorb UVA or UVB radiation or both, are frequently found in chemical sunscreens. When applied to the skin, chemical sunscreens typically seem straightforward and are simpler to disseminate.

Mineral sunscreens: Often referred to as physical sunscreens or inorganic sunscreens, mineral sunscreens contain mineral components like zinc oxide and/or titanium dioxide that act as a physical barrier on top of the skin to reflect and scatter UV rays away from the skin. Mineral sunscreens offer broad-spectrum UVA and UVB protection. Due to the mineral particles, they often have a thicker texture and may leave a white cast on the skin.

Both chemical and mineral sunscreens are permitted for use in the sun and can successfully lower the risk of sunburn, ageing skin, and skin cancer. Which sunscreen is "better" depends on the needs, skin type, and individual preferences. It's important to consider the following:

Chemical sunscreens are typically simpler to apply and might be more appropriate for daily usage on broader areas of the skin, including the body. They frequently have a lighter texture, making them preferable for everyday use when concealer or other skin care products are worn.

Niacinamide sunscreens that have become increasingly popular recently come under mineral sunscreens. On the other hand, those with sensitive skin or a history of skin allergies might prefer mineral sunscreens because they are less likely to irritate their skin. Also, because they function by sitting on top of the skin, they offer protection right once, in contrast to chemical sunscreens, which may take some time to operate because the skin needs to absorb them first.

Mineral sunscreens like a niacinamide sunscreen may also be recommended for application on more delicate body parts like the face and neck since they can act as a physical barrier to block UV rays and are less prone to irritate the eyes.

It's also important to remember that certain chemical sunscreens, particularly those that contain oxybenzone, have sparked environmental worries due to their potential effects on coral reefs and other marine ecosystems. In contrast, mineral sunscreens are typically considered more environmentally benign since they don't include these potentially dangerous ingredients.

The sunscreen that you feel comfortable using consistently is the one that best suits your needs and preferences. The ideal sunscreen should provide broad-spectrum (UVA and UVB) protection, have an appropriate SPF (sun protection factor) rating for your skin type and activity level, and be applied according to the manufacturer's instructions. Chicnutrix Block is the ideal solution for this and the best sunscreen for the face.

What is Chicnutrix Block?

A new sunblock from Chicnutrix is called Chicnutrix Block. It is made in Korea specifically for Indian skin. It is made using potent and secure components like Niacinamide and Adenosine. It is a broad-spectrum sunscreen with SPF 45 PA+++ that offers UVA + UVB protection, shields against UV radiation and sun damage, and minimises fine lines and wrinkles while keeping the skin hydrated. Chicnutrix Block's advantages include the following:

Being easy to carry.

Suiting all skin types.

Leaving no white cast.

Being non-greasy.

Having a light formula.

The majority of people are thankful for sunshine, which is a beautiful thing. No matter how grateful you are, protecting your skin from it is essential. Although it should go without saying to apply SPF before being in the sun, many individuals find it difficult to accept that SPF is also important indoors, especially in light of society's increasing infatuation with screen time.

Blue light and UV deterioration build up over time. This implies that the more exposure you have to it—whether through extended outdoor trips or prolonged inside streaming sessions—the more at risk your skin is. Due to this, there is no argument about wearing sunscreen indoors. That is necessary.


You may have a few concerns about sunscreens. The most frequently asked questions about sunscreens are answered here.

What is SPF?

A sunscreen's ability to shield the skin from UVB (ultraviolet B) light, which causes sunburn, is measured by the SPF (Sun Protection Factor), an acronym for Sun Protection Factor. A sunscreen with an SPF of 30 blocks is approximately 97% of UVB rays, whereas one with an SPF of 50 blocks is around 98%. Higher SPF values indicate more UVB protection. Although UVA (ultraviolet A) radiation can also contribute to skin ageing and skin cancer, SPF only measures the extent of protection against UVB radiation.

How much sunscreen should I use?

Sunscreen should be applied liberally and uniformly to guarantee enough coverage and protection. A complete body application of sunscreen should use around one ounce (30 millilitres) to adequately cover all exposed skin. This equates to around a shot glass' worth of sunscreen.

How frequently should sunscreen be reapplied?

It is typically advised to reapply sunscreen every two hours, immediately after swimming, sweating profusely, towel drying, and after being in the sun for an extended time. The SPF of the sunscreen, the amount of sunlight, physical activity, and other individual characteristics may all affect this, though.

Can I apply sunscreen to young children and infants?

In addition to employing shade, protective clothes, hats, and sunglasses, it's crucial to keep babies and young children well-protected from the sun. Yes, it is safe to apply sunscreen to babies and young children. Nevertheless, it is essential to choose a sunscreen explicitly designed for sensitive skin and to follow the advice of a physician or dermatologist.

Can I use sunscreen that has expired?

Using sunscreen that has passed its expiration date is typically not advised because the level of sun protection may be diminished as the active components lose some of their potency over time. Always ensure the sunscreen is still effective by checking the expiration date on the bottle. Moreover, keeping sunscreen in a cool, dry environment can aid in preserving its efficacy.

Can I wear sunscreen inside or on cloudy days?

Sunscreen should still be worn even on cloudy days and inside because UV radiation can still pass through windows, clouds, and other obstacles. No matter the weather or interior settings, with exposure to natural light, UV radiation can harm your skin even when the sun isn't shining strongly. For this reason, sunscreen protection is essential no matter where you are, as mentioned in the blog above.

Can I apply sunscreen to any skin?

All skin types can use sunscreen, yes. Sunscreens come in various formulas, especially those designed for distinct skin types, including oily, dry, sensitive, or acne-prone skin. It's critical to select a sunscreen appropriate for your skin type and consider any particular skin issues you may have. Furthermore, Chicnutrix Block is the best because it works for all skin types, moisturises the skin, and is the best sunscreen for oily skin.

Sunscreen is the ultimate skin saviour; apply it regularly, even indoors, and enjoy skin that shines with favour! So, Block the sun, not the fun, with Chicnutrix Block!
