We all know a good skincare routine is essential for healthy, glowing skin. However, harmful UV rays can penetrate the clouds, putting our skin at risk of damage. Sun damage isn’t just about sunburn; it can lead to premature ageing and even increase the risk of skin cancer. That’s where SPF, or Sun Protection Factor, comes in.
In fact, Ireland experiences higher ultraviolet (UV) levels than one might expect, owing to its location and atmospheric conditions. This handy rating system tells you how well a sunscreen protects your skin from UVB rays, the main culprit behind sunburn.
What is SPF?
SPF, the Sun Protection Factor, protects your skin against the sun’s harmful rays. It tells you how much longer you can stay in the sun without burning compared to not wearing sunscreen. So, an SPF 30 is good, as this sunscreen lets your skin handle 30 times more UVB exposure before burning. This is the most common question: how long do SPF 30 and SPF 50 last? The answer is that SPF 30 filters out approximately 97% of UVB rays, while SPF 50 filters out about 98%.
But there’s more to the sun’s wrath than just sunburn. UVA rays penetrate deeper, causing wrinkles and premature ageing. While SPF for face primarily focuses on UVB protection, many sunscreens now offer “broad spectrum” coverage, meaning they shield against both UVA and UVB rays.
How Does SPF Protect Your Skin?
SPF forms a barrier on the skin’s surface that absorbs, reflects, or scatters UV rays before they penetrate the skin. This helps prevent sunburn, skin damage and reduces the risk of skin cancer. Incorporating SPF into your routine gives your skin a fighting chance against sun damage, keeping it healthy and youthful.

How To Choose The Right SPF Product?
When it comes to sun protеction, SPF (Sun Protеction Factor) is your guidе. This numbеr indicatеs how еffеctivеly a sunscrееn shiеlds your skin from UVB rays. Whilе SPF 50+ offеrs a slightly highеr protеction lеvеl (blocking 98% of UVB rays compared to SPF 30’s 97%), thе diffеrеncе for daily usе in Irеland is minimal.
We are often asked questions: Is SPF 15 enough, or is SPF 30 or 50 better?
Hеrе, SPF 30 providеs amplification against our climatе’s UV rays. But choosing thе right SPF goеs bеyond thе numbеr. Considеr your skin typе – oily skin might bеnеfit from a non-comеdogеnic (won’t clog porеs) formula — and activity lеvеl. If you swеat a lot during еxеrcisе, a watеr-rеsistant sunscrееn with SPF 30 is a great choice. Rеmеmbеr, consistent application is kеy, rеgardlеss of thе SPF rating.
How To Use SPF Effectively?
Don’t skimp on sunscreen! Apply liberally — about 2 tablespoons for the face and body, ensuring thorough coverage. Remember, reapplication is crucial. Reapply your best face SPF every two hours, and more often, sweat or swim. Don’t forget your lips — use an SPF lip balm for complete sun protection. Make it a habit of using SPF for face daily. These simple steps help maximise the effectiveness of SPF and reduce the risk of sunburn and skin damage.
