Detailed answer

To prevent hyperpigmentation during swimming, it is important to take certain precautions. Firstly, always apply a broad-spectrum sunscreen with a high SPF before swimming. This will help to shield your skin from harmful UV rays. Additionally, it is advisable to wear protective clothing, such as a wide-brimmed hat and a rash guard, to further minimize sun exposure. It is also essential to avoid swimming during peak sun hours, usually between 10 am and 4 pm, as this is when the sun's rays are the strongest. After swimming, remember to cleanse your skin thoroughly and apply moisturizer to keep it hydrated. Following these steps will help protect your skin and reduce the risk of hyperpigmentation.
