Moisture support
Use lotion or cream on dry-prone areas during the highest-stress days. Consider room humidifier use at night on peak DSI days.
Sun care
Use your DSI-matched moisturizer, then broad-spectrum SPF 30+ sunscreen on exposed skin. Choose water-resistant sunscreen for swimming or sweating, and reapply at least every two hours while outdoors.
Add shade, protective clothing, a hat, and sunglasses when practical; UV can still be meaningful on cloudy days.
