Think You Don’t Need Sunscreen Indoors? Here’s What Really Happens
Think sunscreen is only for sunny days outdoors? Think again. Even when you’re inside your home, office, or car, your skin isn’t completely safe. From harsh UV rays sneaking through windows to blue light from your screens, skipping sunscreen - even indoors - can silently damage your skin over time.
Why Sunscreen Is a Daily Essential
Sunscreen isn’t just a summer essential - it’s your skin’s everyday defence shield. Whether you’re lounging by the beach, driving in traffic, or working under artificial lights, your skin faces constant exposure to harmful rays and visible light. Without sunscreen, you leave your skin unprotected, inviting issues like dullness, pigmentation, tanning, and premature ageing.
How Indoor Light Damages Your Skin
Most of us spend our days surrounded by LED lights, laptop screens, and smartphones - all sources of high-energy visible (HEV) light, commonly known as blue light. This light penetrates deeper into the skin than UVB rays, leading to oxidative stress, collagen breakdown, and the formation of free radicals. Over time, this results in fine lines, uneven skin tone, inflammation, and dullness, particularly in Indian skin types that are more prone to pigmentation.
UVA Rays Don’t Stop at Your Windows
Even if you’re indoors, UVA rays - known as “ageing rays” - can easily pass through glass windows. So, sitting near natural light or driving in daylight exposes your skin to the same risks as stepping outside. Many people who “hardly go out in the sun” still show signs of photo-ageing, such as wrinkles and dark spots, because of this hidden exposure.
Skipping Sunscreen After Skin Treatments Can Backfire
If you’ve undergone chemical peels, laser treatments, or injectables, sunscreen becomes even more important. Neglecting it can lead to delayed healing, irritation, and reversal of the benefits from your procedures. Your freshly treated skin is extra sensitive and needs protection from all light sources to recover effectively.
How to Protect Your Skin Indoors
To maintain healthy, radiant skin, dermatologists recommend:
Skipping sunscreen indoors might seem harmless, but it quietly accelerates skin ageing and damage. The light from your screens, lamps, and windows is enough to compromise your skin barrier. Make sunscreen a non-negotiable step in your daily skincare routine - rain or shine, inside or outside - because your skin deserves round-the-clock protection.

To maintain healthy, radiant skin, dermatologists recommend:
- Use a broad-spectrum sunscreen with SPF 30 or higher, even when indoors.
- Choose sunscreens with blue light protection, especially those containing iron oxides, niacinamide, or antioxidants.
- Reapply every 2–3 hours if you’re exposed to light, screens, or heat.
- Apply sunscreen every morning, regardless of weather or sunlight intensity.
