Apply Sunscreen: Swimming is more harmful as, water acts like a lens and lets the sunlight penetrate deeper into the skin. Apply water resistant sunscreen lotion 20-30 minutes before going to the beach and re-apply it after swimming.
Cocoa effect: Use cocoa butter to prevent harmful peeling; they come in reasonable OTC (Over-the-counter) brands.
User Water-Resistant make up products: All make up products should be water resistant. To prevent sun burnt lips, apply a medicated lip protection guard with SPF.
Hair Care: For hair one must use a hair conditioner, or a hair moisturizer and detangler, so to avoid hair becoming rough and brittle. Hair is more sensitive to hard water.
Hats on: Wear wide hats when on the beach. Also drink lots of water to keep yourself hydrated.
