It's generally not recommended to leave sunscreen on overnight. Leaving sunscreen on can prevent your skin's natural oils from escaping, which can lead to clogged pores and breakouts. This is because sunscreen, especially chemical sunscreen, can be thick and occlusive, meaning it creates a barrier on the skin that prevents moisture from escaping.
While it's not necessarily harmful, leaving sunscreen on at night can also lead to skin irritation, clogged pores, and acne breakouts. Your skin needs time to breathe and regenerate overnight, and sunscreen can interfere with this process.
In summary, it's best to wash your face and body with a gentle cleanser before bed, removing any sunscreen residue. This allows your skin to breathe and prevents potential irritation and breakouts.
