Serum antioxidants, including Vitamin C Serum, are recommended for PRP microneedling after care, as their properties are optimal in helping the wounded skin by reducing irritation. PRP microneedling aftercare may also include the incorporation of Hyaluronic Acid Serum, especially if the patient’s skin feels drier than normal following a Derma Pen treatment. HA Serum is a powerful hydrator and aids in restoring balance to the skin.
