Opened vs Unopened Shelf Life
Most chemical sunscreens perform best within 12 months after opening; unopened bottles are often fine for up to 3 years if stored cool and dark.
Mineral filters (zinc oxide/titanium dioxide) are more stable, but oils and film formers can still degrade.
- Find the PAO symbol (e.g., 12M after opening)
- Store cool and away from sun; close the cap tightly
- After high-heat trips, try to finish within 6 months
Is it safe to use expired sunscreen?
Not recommended. UV filtration may drop and preservatives can fail, increasing irritation risk. Choose a fresh SPF50+.
- Check signs: separation, off-odor, or color change — discard
- Sensitive skin: prefer mineral formulas and check dates
- For short indoor exposure, rely more on sleeves/shade
Choosing and Reapplying
UV 6 or in summer: SPF50+ / PA+++ to PA++++; reapply outdoors every >1 hour.
Humidity 60% or oily skin: mattifying primer + water-resistant base + setting spray.
- Two-finger rule to cover face and neck
- Makeup on: reapply with mists or cushions; keep spray away from nose/mouth
- Mask commute: let sunscreen set before base; blot T-zone
