To avoid a higher probability of bruising, we recommend stop taking over-the-counter blood thinners, such as aspirin or ibuprofen, 72 hours prior to your appointment. A few days prior to your appointment avoid consuming alcohol, waxing or using any type of hair removal product on the area of injection, and stop using topical products such as tretinoin, glycolic acids, retinols or any other anti-aging products that could potentially add irritation to the area of injection. Consult our nurse practitioner for further instructions or questions. DM or call us for more details.
