applying sunscreen at night

Applying sunscreen at night isn’t really necessary, especially when you’re inside and away from direct sunlight. Sunscreen is formulated to protect the skin from harmful UV rays, which aren’t a concern after the sun sets. Your friend’s right that sunscreen typically serves its purpose during the day when you’re exposed to sunlight. At night, focus should ideally be on products that encourage skin repair and hydration. When you apply moisturizers or other treatments in your nighttime skin care routine, those are designed to work without the interference of sunscreen. Sunscreens can form a barrier that might prevent your night-time products from fully absorbing into the skin, potentially diminishing their effectiveness. If you’ve read sources suggesting nighttime sunscreen use, it’s possible they’re referencing specific contexts like high-energy visible (HEV) light from screens, which might be a consideration for some. However, even for this, a good antioxidant or a blue light-specific product might suffice rather than sunscreen. Stick to deleting your face thoroughly, following with a suitable moisturizer and perhaps serums or retinoids appropriate for your skin type. If you’re worried about blue light, there are easier ways like adjusting screen settings, using night mode, or reducing screen time. Overall, you’re unlikely missing something crucial by not applying sunscreen at night. Save it for daytime when it can really do its job.
