Sunscreen works by forming a protective layer on your skin that absorbs and blocks harmful UV rays. This helps prevent sunburn, skin damage, premature aging, and reduces the risk of skin cancer.

Some sunscreens use older UV filters that break down in sunlight, which means they need to be reapplied every 2–3 hours. AccuFix's sunscreens are made with modern, photostable filters that stay effective for much longer, so you only need to reapply if you’re sweating, swimming, or wiping your skin.

Yes, sunscreen does expire. Most sunscreens have a shelf life of 2 to 3 years, but you should always check the expiry date on the packaging. Using expired sunscreen may reduce its effectiveness and leave your skin unprotected from harmful UV rays.

The best sunscreen is one that suits your skin type, offers broad-spectrum protection, and has an SPF of 30 or higher. For oily or acne-prone skin, lightweight, non-comedogenic formulas are ideal. If you have sensitive skin, go for physical (mineral) sunscreens with zinc oxide or titanium dioxide.

Sunscreen is generally not needed after 6pm—especially if the sun has set or UV levels are low. However, if you’re still outdoors and the sun is visible, apply sunscreen to stay protected. UV rays can linger until sunset, particularly in summer or tropical areas.
