Spot treatments work by delivering acne-fighting ingredients directly to the offending blemish. Spot treatments can help reduce redness, swelling, and pain. They can also help loosen or dissolve the blockage within the pore that created the blemish in the first place.
Applying a spot treatment after cleansing can allow the ingredients to work their way deep into the skin. As well as treating existing pimples, these products can target scarring and stop new breakouts.
