They are hardly noticeable because they are matte and translucent and blend easily into the skin. It is just satisfying to see your blemish disappear and heal faster. When I feel a blemish coming up, I put one of these patches on it and the blemish just shrinks so much faster and it gets all the gunk out. These patches also prevent me from wanting to pick my blemishes. Don't we all have that urge that we want to touch a blemish and usually making things worse?
