After application, avoid sweating, heat, steam and water for 24 hours. Try to workout, shower and tan before your appointment. Especially important, do not spend time out in the hot sun for at least 24 hours after your appointment.
Oil must be avoided on and around your new lashes every day. Beware of concealers, foundations and eye cream with oils. A good rule of thumb is to avoid getting anything on the lashes in general.
Remember to wash your lashes at least once a day with the Fluff Cleanser and Makeup Remover (it's specially formulated specifically for the lashes.)
