How to choose sunscreen: Sunny days feel wonderful with beach trips, walks, or quick errands. And yes, sunlight boosts vitamin D and mood. But too much UV can harm your skin, which is why sunscreen matters. With SPF numbers, lotions vs. sprays, “water-resistant” labels, and more, it’s easy to get confused about what to choose and how to use them. Let’s simplify it.
Why do you need sunscreen?
You need sunscreen because the sun’s UV rays damage skin. UVA accelerates ageing with wrinkles or spots, and UVB causes burns and raises skin-cancer risk. Those rays reach you even on cloudy days and through windows.

What does SPF mean?
SPF means sun protection factor. It tells you how well a sunscreen shields against UVB. Higher numbers add a bit more protection, but no SPF blocks 100%. For most individuals, SPF 30+ represents the optimal level of protection. Wearing a broad-spectrum SPF daily is one of the simplest, most effective ways to protect skin health and keep it looking its best.
Different types of sunscreens:
There are two types of sunscreens based on how they work. Chemical sunscreens (e.g., avobenzone, octocrylene) absorb UV and convert it to heat. They spread easily, feel lightweight, and usually leave no white cast, making them popular for daily wear and swimming. Mineral sunscreens, which include zinc oxide and titanium dioxide, sit on the skin’s surface to deflect or scatter UV rays. They work immediately after application and are often preferred for sensitive skin and children, although they may leave a white or chalky finish unless tinted or micronised.
How to choose sunscreen for your skin type?
For oily or acne-prone skin, pick an oil-free, non-comedogenic gel or water-based sunscreen with a matte finish. Dry skin does better with formulas that include moisturisers, glycerin or hyaluronic acid. For those with sensitive skin, choose mineral (zinc oxide/titanium dioxide) options without fragrance or high alcohol.
How and when should you apply sunscreen?
Apply sunscreen every morning. Chemical sunscreens need 15–30 minutes before sun exposure, while mineral sunscreens work immediately. About 1 shot glass (≈30 ml) of sunscreen is enough for the whole body; the two-finger rule is a useful guide for the face and neck. Choose an SPF 30+ broad-spectrum sunscreen that can protect you from both UVA and UVB rays. Reapply sunscreen every 2 hours, as well as after swimming, sweating, or towel-drying. If the product is labelled as water-resistant, it protects for nearly 40 minutes in water; after that, reapplication is necessary.
