"If you notice your products are being used, keep them in a separate area from your roommates if possible to avoid any confusion or further temptation," said Myka. "Worst case scenario, take your products out of the communal area or bathroom and keep them in your room or in a drawer that is just yours."
If you keep your face masks or eye cream in the fridge you share with your roommate, consider getting a mini skincare fridge to keep in your room.
