Essential oils

While some essential oils have benefits such as antioxidants or natural antibacterial properties, they can often do more harm than help, according to Paula's Choice.

Be warned: Essential oils such as rosemary, lemongrass, thyme, cinnamon, citronella and tea tree oils have been said to be helpful for skin, but they can also cause major irritation and redness. You should especially avoid fragrant oils.

Sugar

Joshua Ross, celebrity aesthetician and founder of West Hollywood's SkinLab, told Byrdie that he doesn't recommend sugar scrubs, as they can cause irritation and microtears. He says you're much better off with a washcloth and a mild chemical exfoliator.
