Discontinue using any active exfoliants for 5-7 days before coming in for your treatment. This includes but is not limited to retinol, salicylic acid, glycolic acid, and benzoyl peroxide. The risk of having an adverse reaction may increase if you use these products too closely to receiving microneedling. Let your aesthetician know if you are taking any antibiotics or prescription medications. These may also increase your skin’s sensitivity. Avoid direct sunlight and be sure your skin is not sunburnt when you come in for your treatment. Ideally you will want to discontinue using any medications that could thin your blood and increase your chances of bruising (NSAIDs, aspirin, ibuprofen etc). Caffeine and alcohol also fall under the same category and can cause blood-thinning which can lead to more bruising. Avoid them if you can for 1-2 weeks before your appointment.
