To determine the most suitable sunscreen for your face, consider your skin type and specific needs. If you have oily or acne-prone skin, opt for oil-free, non-comedogenic formulas. Dry skin benefits from moisturizing sunscreens, while sensitive skin requires hypoallergenic and fragrance-free options. Look for broad-spectrum protection with SPF 30 or higher, and don't forget to patch test new products to ensure compatibility.
