Sunscreen to prevent sunburn

Start by selecting a broad spectrum sunscreen with SPF 30 or higher to prevent sunburn. Look for UVA/UVB coverage and water resistance if you’ll be sweating or swimming, and always check the label for broad spectrum protection. Brands like Neutrogena and Coppertone offer reliable options, with sensitive-skin formulas from other trusted lines. Choose based on your activity, skin type, and ensure the product’s expiry date is current.

SPF measures protection against UVB rays, the portion of sunlight that causes sunburn. Broad-spectrum labeling ensures protection against UVA rays as well, which contribute to longer-term skin damage. Higher SPF blocks more UVB, but the increase is not perfectly proportional, and you still need to reapply every two hours or after sweating or swimming. Combine SPF with shade, protective clothing, and reapplication for best results.

For brief outdoor time, a broad-spectrum sunscreen with SPF 30+ is usually enough. For long days at the beach or on outdoor sports, choose SPF 50+ and a water-resistant formula to maintain protection when you sweat. Remember to complement sunscreen with hats, sunglasses, and protective clothing for extra safety.

Apply sunscreen 15 to 30 minutes before sun exposure to allow it to absorb. Reapply every two hours, and more often if you swim, sweat, or towel off. Use a generous amount: about a nickel-sized dollop for the face and neck, and a full-body application when needed. If you wear makeup, consider reapplying with a product designed for makeup wearers or a lightweight layer underneath.

Choose fragrance-free, broad-spectrum sunscreen with SPF 30 or higher for sensitive skin or kids. Look for mineral filters like zinc oxide or titanium dioxide if possible. Patch test on a small area first and avoid known irritants or sensitive ingredients. Reputable brands such as Neutrogena, Coppertone, and La Roche-Posay offer lines aimed at sensitive skin and young users.
