Choosing the right sunscreen requires evaluating SPF level, UVA/UVB protection, skin type, usage conditions, and ingredient structure together. SPF 30 is generally recommended for daily use, while SPF 50 may be safer during intense sun exposure. Non-comedogenic formulas are often better for oily skin, while moisturizing formulas suit dry skin more effectively. Comfort and consistency of use are among the most important selection factors.
