Immediately after shaving, you have let the guard down on your face. Shaving removes the top layer of the epidermis and leaves the pores open to all kinds of risk factors. The risk factors can cause dryness, damage, ingrown hairs, irritation and even premature aging. Aftershaves are used to protect the skin. Aftershaves typically come in two forms: splash and balm. Most aftershave splash contains Witch Hazel and Aloe Vera, which will leave the skin clean and pores closed. The balm is heavier and has a longer lasting effect, locking in moisture.
