If you are swimming at a pool, there are often showers on site that you can use before you get into the pool.
You can find moisturizer with squalene and zinc online or at your local drugstore.
Always reapply sunscreen every time you get out of the water to ensure your skin is protected from the sun and at least every two hours. Apply generously, use about enough to fill a shot glass.
If you tend to get in and out of the water while you swim, try to shower between swims. This will help to reduce the amount of time the pool or ocean water stays on your skin. Even just using a spray bottle filled with tap water may help to rinse yourself off a little.
You should also wash your hair during the shower, as the chemicals in pool water can damage your hair if they stay on your scalp for too long. Salt water can also be harsh on your hair so you should shower using mild shower gel after you swim in the ocean.
If you are going to swim indoors, go for a pool that has good ventilation and low chlorine content.
