1. HORMONAL CHANGES
Puberty is one of the biggest acne causes.
Acne forms, and becomes worse, when your body produces higher volumes of sebum than before and you aren’t able to regularly clear your pores.
2. EXCESS DEAD SKIN CELLS
When too many dead skin cells travel to your pores on the surface of your skin, they can clump together to clog your pores and appear as a pimple.
3. BACTERIA CONTAMINATION
More severe acne occurs when bacteria also becomes trapped with sebum in your pores.
Bacteria can cause inflammation and redness and can lead to the formation of painful cysts under the skin.
Cysts are lumps which, like pimples, contain pus, however, they don’t form a head on the outside of the skin.
Try to avoid touching your face, remember to regularly change your pillowcase and clean your phone screen to avoid contamination.
4. YOUR SKIN-TYPE
If you have oily skin, the excess oil on the surface of your skin can also block pores and cause acne.
If you have combination skin, you may have acne prone skin in the oilier areas of your face – typically on the forehead and nose.
