Why Amount Matters

Using too little sunscreen drastically lowers its effectiveness. Less product can reduce SPF 50 to SPF 30 or less, offering far weaker UV protection.

Coverage Tips

Don’t forget ears and neck when applying sunscreen each morning. These often-missed areas are also prone to sun damage.

Daily Routine

Sunscreen isn’t just for sunny days — UV exposure happens even on cloudy days. Make it a part of your everyday skincare before stepping outside.

Reapplication Reminder

For prolonged sun exposure, reapply sunscreen every 2–3 hours. This keeps your protection level high, especially if you’re outdoors or sweating.
