Scabs form as one of the body's healing mechanisms when the skin is scratched, punctured or otherwise injured, and can also form after a blemish has been picked or squeezed at. Deep wounds can result in scarring, and though you can take measures to avoid scars, it can also be important to hide scabs for job or performance purposes. Use concealer to hide scabs on the face as well as the rest of the body, but remember to blend the makeup well to avoid a "caked" look.
Inspect the scab to ensure it is still fully attached to the skin. If the wound is at all open, refrain from using concealer to avoid getting makeup in your bloodstream. Use a healing ointment or liquid on the scab, such as raw apple cider vinegar, to help speed the healing process and prep the scab for makeup.
Apply a moisturizer to the scab if possible to make the skin appear less flaky, and to give the makeup something to bind to other than your skin. The skin around scabs is often dry, and using makeup on dry skin will only make the product more visible as opposed to covering the scab successfully.
Dab at the scab with your concealer. Use your finger to pat the scab rather than rubbing it, which not only can remove the scab completely but also helps the makeup set on the scab better. Apply concealer until the scab is completely covered.
Use your finger or a cotton swab to remove excess makeup around the scab.
Dust loose powder over the scab to set the concealer and keep it in place all day and night.
Use stick concealers for thicker coverage. Always wash the face before applying makeup to avoid blemishes, which can subsequently turn into more scabs you will have to cover.
