Detailed answer

Having a tan does not provide sufficient protection against the harmful effects of the sun. Even with a tan, your skin is still at risk of sunburn, skin damage, and skin cancer from prolonged sun exposure. Sunscreen helps to block harmful UV rays and decrease the risk of these negative consequences. It is important to note that a tan is typically an indication of sun damage and does not provide a reliable means of protection. To effectively protect your skin, apply broad-spectrum sunscreen with at least SPF 30, even if you already have a tan. Additionally, it is recommended to seek shade during peak sun hours, wear protective clothing, and use other sun protection measures alongside sunscreen for optimal protection.
