What is the correct way to apply sunscreen?

Applying sunscreen "generously and evenly at least 15 minutes before sun exposure" is essential for ensuring effective protection against harmful UV rays. This timeframe allows the active ingredients in sunscreen to properly bind to the skin, maximizing their protective capabilities. Generosity in application means using enough product to cover all exposed skin areas adequately, which is crucial for preventing sunburn and long-term skin damage.

Furthermore, evenness in application ensures that there are no missed spots, which could lead to uneven protection and potential skin issues. It's also important to reapply sunscreen every two hours, or more often if sweating or swimming occurs, to maintain adequate sun protection throughout the day. This practice is necessary for achieving optimal benefits from sunscreen, as UV exposure can still occur even on cloudy days or in shady areas.
