Before you proceed with permanent eyeliner or lash extension treatment, you may want to have a skin test done. A skin test will make sure you don’t have any skin allergies or medical conditions that may impact your eligibility for treatment due to possible adverse reactions. Some other precautions include: • Avoid working out on the day of the procedure as your body heat will expand your pores and negatively affect results • Avoid heavy sunlight exposure for three days before treatment to prevent sunburn • Avoid drinking coffee or alcohol before treatment, as caffeine and alcohol thin the blood which may cause you to bleed during treatment • Wear glasses to your appointment instead of contacts • Stop using any eyelash growth enhancement products at least 30 days before treatment • Avoid tinting or perming your lashes two days before treatment • Do not take any blood thinning medications or products 24 hours before your appointment — contact your doctor if you’re taking prescription blood thinning medication
