My face is very sensitive and gets red especially after i am exposed to sun rays and i constantly use a cleanser and a sunscreen so what should i do ?

Sunscreen: Cleaning your skin is good, but don't dry it out, or scrub when you wash. Use a mild cleanser and pat dry. Use sunscreen regularly!! You will need to reapply every hour or 2 when you are out in the sun. Wear a broad brimmed hat to protect your face as well. Drink a lot of water! That helps keep your skin moisturized and less sensitive to sun damage. If not better, see your doctor
