Detailed answer

Using anti-aging creams before a facial biopsy can potentially interfere with the results of the biopsy. These creams often contain active ingredients that can affect the appearance of the skin and potentially mask or alter any abnormalities that needed to be evaluated. It is important for the healthcare professional performing the biopsy to have a clear view of the skin and be able to accurately assess any suspicious areas. Therefore, it is advisable to refrain from using any skincare products, including anti-aging creams, on the specific area intended for biopsy for a few days prior to the procedure. It is always best to consult with your healthcare provider or dermatologist for specific instructions and recommendations based on your individual case.
