4. Absence of Blackheads
One of the other clues when it comes to comparing rosacea with acne is that acne goes through a cycle of specific skin changes. If you have acne, then this will be caused by pores becoming blocked. Pores are of course tiny holes in your skin, and when these get jammed with grime and bacteria, it can then lead to the area getting infected.
When this first happens, you’ll notice tiny blackheads forming – which are the clogged pores. These may then get infected by bacteria, resulting in the appearance of full-blown spots.
Various things will contribute to the formation of spots then, ranging from having larger pores, to begin with, all the way to producing too much oil and sebum. Anything that increases the bacteria on your face is also liable to create more issues.
For these reasons then, you may be able to tell the difference between spots and rosacea by looking carefully for the other stages of spots. If you don’t notice any blackheads, then perhaps it is not acne.
