There isn’t a single specific downside to using citrus oils daily in your skincare routine, as they are both beneficial and safe. Citrus oils are loaded with antioxidants, which help to fight free radicals that can cause skin damage and inflammation. Additionally, they contain beneficial vitamins and minerals such as vitamin E, iron, calcium, magnesium, zinc ,and folate. These nutrients work together to nourish the skin while protecting it from environmental aggressors like pollution or UV radiation.
When used correctly (i.e., only in low concentrations), citrus oils can also improve the texture and appearance of skin tissue by acting as an emulsifier and thickening agent. So there really is no bad side to using them day-in and day-out!
