Can I Leave Sunscreen On Overnight?

No, you generally shouldn't leave sunscreen on overnight. While sunscreen protects your skin from the sun's harmful UV rays, leaving it on for extended periods can have negative consequences.

• Clogged Pores: Sunscreens, especially those with oil-based active ingredients, can clog pores and lead to breakouts. The active ingredients are oils that need to be removed before bed. As the day progresses, sunscreen can break down and further clog pores, preventing the absorption of natural skin oils. This creates a breeding ground for acne-causing bacteria.

• Dryness: Some sunscreens can be drying, and leaving them on overnight can exacerbate dryness. [Source: Lifehacker article states a dermatologist said leaving sunscreen on can unnecessarily dry out the skin].

Exceptions and Considerations

While generally it's best to remove sunscreen before bed, some individuals may have different experiences. It's important to note that individual reactions vary greatly. Always pay attention to your skin's response. If you notice no negative effects after sleeping with sunscreen on, this may be acceptable for you. However, this is not a universally recommended practice.

Best Practices

• Cleanse your face before bed: Removing sunscreen is a crucial step in your nighttime skincare routine.
• Choose a non-comedogenic sunscreen: Look for sunscreens labeled "non-comedogenic," which are less likely to clog pores.
• Listen to your skin: If you experience any irritation or breakouts, discontinue sleeping with sunscreen on.
