Protecting scabs with make-up generally is a useful solution to conceal them and make them much less noticeable. There are a couple of alternative ways to do that, relying on the dimensions and site of the scab.
For small scabs, you need to use a concealer that’s near your pores and skin tone. Apply the concealer on to the scab and mix it out along with your finger or a make-up sponge. If the scab is barely raised, you could want to use a second layer of concealer.
