Does sunscreen go out of date?
Yes, sunscreen does expire. After the expiration limit, its effectiveness is reduced, potentially leaving your skin less protected from UV rays. Always check the expiration date on the packaging.
When to use sunscreen with SPF?
SPF should be used every day, at least 30 minutes before going outside. UV rays can still cause damage on a cloudy or rainy day, so daily use is key. Find more information here.
Should I wear SPF in the winter?
Yes, SPF is recommended even in winter. UV rays in winter can still cause premature ageing and pigmentation, elevating your risk of skin cancer. Snow can also reflect UV rays, increasing your skin’s exposure.
What does SPF stand for in sunscreen?
SPF means Sun Protection Factor. It indicates how well a sunscreen protects your skin from UV rays, the main cause of sunburn and skin damage. For example, SPF50 filters about 97% of UVB rays when applied correctly. Dermatologists recommend reapplying SPF every 2 hours.
