A. Taking care of your skin while trekking is essential to ensure you remain comfortable and avoid skin problems. Apply broad-spectrum, high-SPF sunscreen sunscreen with a high SPF rating to shield your skin from the sun's harmful UV rays. Reapply regularly, especially in high-altitude areas where UV exposure is stronger. Staying hydrated is crucial for your skin. Drink plenty of water to keep your skin moisturized from within. Choose moisture-wicking and breathable clothing to help regulate your body temperature and reduce sweat-related skin issues. Keep a change of clothes in case you get wet, and wear moisture-wicking socks to prevent blisters. Protect exposed areas from wind and cold by layering appropriately. Once your trek is complete, clean your skin thoroughly to remove dirt and sweat. Apply moisturizer and aa facewash to rehydrate your skin and relieve any dryness.
