The best way to avoid tan is by practicing sun safety: Sunscreen: Apply sunscreen with SPF 30 or higher, even on cloudy days. Reapply every two hours, or more often if sweating or swimming. Seek shade: Plan outdoor activities for earlier or later in the day, or seek shade during peak sun hours (10 am to 4 pm). Cover up: Wear protective clothing like wide-brimmed hats, sunglasses, and loose-fitting, breathable fabrics.
