“Acrylic nails can be harmful when MMA (methyl methacrylate) liquid monomers are being used,” explains manicurist Sarah Chue, who has worked with celebs like Uzo Aduba and Samira Wiley.

“This ingredient was used early in the nail industry, complaints included severe nail damage, soreness, nail infections, and respiratory problems from inhaling. Because of this, the FDA banned the use of MMA in numerous states. Unfortunately, it is still being illegally used because it is cheap," she adds. Hence, why a traditionally pricey mani's cost could be slashed in half. 

Another problem? The bond between artificial and natural nails is must stronger than a “real” nail bed. Meaning if the nail rips or lifts up, that gap provides a rich, moist, warm environment for bacteria and fungi (e.g., an infection) to grow. Prolonged time on the nail allows infections to worsen. With acrylics, the opposite – drying out of natural oils – can occur, which can cause damage and splitting.

“You need to be careful with the salon you’re choosing to make sure they’re taking care of the nails in the most gentle way,” cautions Smith & Cult Beauty ambassador and celebrity nail artist Sarah Bland. 

“When you have soft gels on your nails, nobody should ever use a dremel to remove the gel. It should only be removed with a hand file and soaked with acetone, it should never be drilled off.”
