Key Features to Look for When Choosing Sunscreen for Optimal Skin Protection
Knowing how to select the right sunscreen can help improve your protection against sun damage. Dr Jaafar, a skincare expert, highlights two key features to check on sunscreen labels for effective use.
First, it is vital to look for a broad-spectrum label. This means the sunscreen protects against both UVB and UVA rays. UVB rays are primarily responsible for sunburn, while UVA rays can contribute to skin aging and cancer.
Another important factor is the Sun Protection Factor (SPF) number. Dr Jaafar explains, "The number tells you how much longer you can stay in the sun before burning, compared to wearing no protection at all. So, SPF 30 means it would theoretically take 30 times longer for your skin to burn. In real life, however, factors like sweating, swimming, and simply not applying enough all reduce that protection significantly, so it is essential to apply more than normal in those situations."
Choosing a sunscreen with these features can significantly enhance your safety in the sun, especially during the summer months or while on holiday. Always remember to reapply sunscreen as needed to maintain its effectiveness.
