Alcohol thins the blood, and if consumed prior to treatment, you have an increased risk of bleeding and bruising. This is not a great recipe with dermal fillers, as we are often injecting deep into the skin, above periosteum (bone). This means the needle will pass through the dermis, where the vascular structure lays. The needle is generally larger for dermal filler than anti-wrinkle injections, to allow the viscosity of the filler to pass through the needle. Expert injector Dr. Arthur Swift has stated that every time a needle is inserted into the skin, the patient has bruised, it just might not come to the surface, where we can see the bruise. If you were to drink alcohol after bruising, it will prolong healing and potentially cause more swelling in the area.
If if you’re worried about bruising, I advise my patients to avoid blood thinning medications, such as fish oil, ibuprofen, green tea, et c., if not under the care and prescription of their doctor. Over-the-counter medicine – Arnica, is advised to prevent and bring bruising out. This is available at chemists, however, it is not something to take to out weight consuming alcohol.
