Pimples are formed due to clogging of skin pores these are usually seen on face and back. The clogging could be due to blocking of pores with dirt and grime or excess oil secretion. They start as whiteheads or black heads, they can be open pores (blackheads) or closed pores (whiteheads) and if these are left untreated they result into pimple and if a pimple gets inflamed or infected it results into acne.
Pimples start from pubertal age as the body is undergoing hormonal changes and may well continue into adult age or some may even notice pimples for the first time in their late 20's - 30's these could be purely hormonal.

Hormones mainly DHT, pre menstrual flare in women, junk food, dirt & grime, stress, oily skin, cosmetics (use oil free or water based cosmetics to prevent pimples), medications, post laser hair reduction, illness (PCOD) and occupational all of these may result into acne.
The pores on our skin are connected to oil glands and these oil glands secret sebum which can block pores and result into pimples. If the inflammation is right near the surface, a pustule (pus) is formed; if it is deeper, a papule (raised); deeper still and it become a cyst.
