6 Natural Ingredients That You Should Probably Avoid

Citrus juices are said to help lighten dark spots... but it could also cause second degree burns. Yes, the juice contains vitamin C and alpha hydroxy acids, which might seem like a good thing, but remember that these ingredients are used in much lower (and thus, safer) concentrations in your skin care products.

NYC-based dermatologist Dr. Michelle Green explained to Greatist that DIY citrus juice treatments "can cause severe irritation, especially for those patients that have sensitive skin." So, steer clear — you're better off with a good vitamin C serum or AHA toner!
