Yes, sunscreen is necessary even in an AC room.
While it's tempting to think we're safe from the sun indoors, that's not entirely the case. Here's why sunscreen should be a part of your indoor routine:
Why You Need Sunscreen Indoors
-
UV Damage: Even when you're not directly exposed to sunlight, UV rays can still penetrate windows. According to the reference, SPF is essential indoors as well as out, because we need to protect against UV damage.
-
Blue Light Exposure: Digital devices like computers, smartphones, and tablets emit blue light. The reference indicates that SPF is necessary to protect from blue light damage. Blue light can contribute to skin damage, aging, and hyperpigmentation.
-
Cumulative Exposure: Daily exposure, even in small amounts, adds up over time. It's crucial to protect your skin every day, not just when you're outdoors.
How to Choose the Right Sunscreen for Indoor Use
While you might use a heavy-duty SPF for outdoor activities, a lighter formula might be sufficient for indoors:
- Broad Spectrum: Look for a sunscreen labeled "broad spectrum." This means it protects against both UVA and UVB rays.
- SPF 30 or higher: Even for indoor use, a minimum of SPF 30 is recommended.
- Lightweight Formula: Choose a lightweight, non-greasy sunscreen that feels comfortable on your skin.
- Consider Mineral Options: Mineral sunscreens containing zinc oxide or titanium dioxide can be a good option, especially if you have sensitive skin.
- Remember to reapply: Even indoors, if you're in front of windows for long periods, it is a good practice to reapply sunscreen for the best protection.
Practical Tips
- Incorporate it into your Routine: Make applying sunscreen a part of your daily skincare routine, just like brushing your teeth.
- Apply to Exposed Areas: Focus on areas that are typically exposed to light, like your face, neck, and hands.
- Use It Daily: Even on cloudy days, UV rays can still penetrate through the clouds.
Summary

| Blue Light | Yes, from digital devices. |
| Cumulative Exposure | Yes, daily exposure adds up. |
| Indoor Protection | SPF is a necessity |
In conclusion, the reference clearly states that SPF is necessary indoors, in addition to outdoor use, to protect against both UV and blue light damage. This means that despite being indoors, such as an AC room, it's important to wear sunscreen daily for optimal skin protection.
