When investing in sunscreen, you want effective sun protection. SPF (Sun Protection Factor) measures defence against UVB rays, which cause painful sunburn. Always choose a broad-spectrum sunscreen to ensure protection against both UVA and UVB rays.
The rule is simple: the higher the Sun Protection Factor, the greater the UVB protection. However, no sunscreen blocks UV rays completely, and the difference between higher SPFs is smaller than you might think.
SPF 15 blocks around 93% of UVB rays
30 blocks about 97%
50 blocks close to 98%
100 blocks roughly 99%
For example, the Beauty of Joseon Rice Sunscreen With Rice Water & Prebiotic Complex SPF 50+ offers high protection. It remains one of the most trusted choices for daily use, helping to prevent sunburn, premature ageing, and skin cancer.
Water resistance matters for outdoor protection
Water-resistant Sun Protection Factor is vital if you are swimming, sweating, or enjoying long days outdoors. Without it, sunscreen can wash away, leaving your skin vulnerable to dangerous UV exposure.
Sunburn, early wrinkles, and a higher risk of skin cancer all become real dangers without water-resistant protection. However, water-resistant does not mean waterproof. You still need to reapply sunscreen regularly, especially after swimming, sweating, or towelling off.
A good example is Sun Bum SPF 50 Face Lotion, which stays water-resistant for up to 80 minutes. It is ideal for beach trips, sports, and family days in the garden.
SPF by age group: essential guidance for families
According to Franchesca Villar, Beauty Editor at Cosmetify, the right Sun Protection Factor varies by age. For infants (0–6 months), avoid sunscreen and use shade and protective clothing. For babies and toddlers (6 months–12 years), use a broad-spectrum SPF 50 such as Heliocare 360 Pediatric Atopic Lotion Spray SPF 50.
Teens (13–18 years) should apply an SPF 30–50 daily. For those with oily or acne-prone skin, Dermalogica Oil-Free Matte SPF 30 works brilliantly.
Adults (18+) should use SPF 30–50 with skincare benefits like vitamin C or oil control. Older adults (60+) need SPF 30–50+ with hydrating ingredients such as hyaluronic acid or glycerin.
Using the right sunscreen for your age and lifestyle is crucial to protect your skin at every stage of life.
