Numerous common skin care ingredients can also render your skin more susceptible to sun damage, notes Alessandra Caceres, an aesthetician and the founder of Miami Beach's Lavender Facial Bar.

Other common ingredients that lead to sun sensitivity are benzoyl peroxide, hydroquinone, essential oils and salicylic acid. Even if you're only using these products at night, they still make your skin more sensitive in general.
