Experts Reveal Common Mistakes in Sunscreen Application Undermining Skin Protection

In Israel, where sun exposure is nearly constant, sunscreen is a vital part of daily skin care, but many people apply it incorrectly, reducing its effectiveness. Dr. Meital Heber, a dermatology expert, explains that sunscreen must be chosen carefully, applied generously, and reapplied regularly to truly protect against harmful UV radiation. The sun’s rays contribute not only to immediate sunburn but also to premature skin aging, pigmentation, wrinkles, and potentially deadly skin cancers.

Many users apply too little sunscreen, miss exposed areas like ears and neck, forget to reapply after swimming or sweating, or use expired products. Dr. Heber recommends applying about 30 milliliters (a shot glass amount) for full body coverage, 20 minutes before sun exposure, and reapplying every two hours or immediately after water contact. Spray sunscreens should be applied evenly and rubbed in, especially on children’s sensitive skin.

Choosing the right sunscreen depends on skin type and lifestyle; SPF 50 with broad-spectrum UVA and UVB protection is generally advised. Formulations vary from lightweight for oily skin to richer creams for dry skin or those on retinoids. For infants under six months, direct sun exposure should be avoided entirely, while mineral-based sunscreens are preferred for older children.

Sunscreen alone is not enough; additional measures include seeking shade, wearing wide-brimmed hats, UV-protective sunglasses, and light, dense clothing. Dr. Heber emphasizes that sunscreen is a crucial "seatbelt" for skin health but must be used correctly and combined with other protective habits to reduce the risk of skin damage and cancer in Israel’s intense sun environment.
