Pimples are a common skin problem that erupt on the face when sebum oil mixes with the dead skin cells in your pores to create a soft clog called a comedone.

Acne, one of the most common skin disorders for Americans, according to the American Academy of Dermatology, or AAD. It affects 40 to 60 million people. Acne occurs when pores, which are attached to oil glands, become clogged with dirt, bacteria and sebum.

Some of the same ingredients in toothpaste can also clear up excess oil that can get trapped in your pores.

Dirt, oil and bacteria that clog up pores cause lesions or pimples to form, resulting in acne breakouts. According to Women's Health.gov, acne typically affects men and women differently. In adolescence, boys usually experience more severe cases of the condition, while women can break out with pimples at any age.

If a food allergen were responsible for acne, you could simply cut that food out of your diet and have clear, smooth skin in no time. Unfortunately, it’s not that simple. Food allergens do not cause any kind of acne, including cystic acne.

The Acne Resource Center states that acne results from a genetic predisposition influenced by the hormones testosterone and androgen. Diet does not create this common skin condition; it can, however influence the severity of acne and trigger breakouts.

When you suffer from acne, it's usually a product of dead skin and oil forming a plug within a pore, according to the Mayo Clinic. For some people, the presence of a plug increases the chances of infection, which can prompt inflammation of the follicle, resulting in a pustule, nodule or cyst under the skin.

Shoulder acne can be an annoyance, especially during the warmer months. Having breakouts on your shoulders may make you feel self-conscious about wearing sleeveless clothing. Shoulder acne can be severe, because the pores are larger on this part of the body and sizable lesions can appear.

When people look at your skin, it relays non-verbal communication to them. A nose that appears oily may seem to be the result of infrequent or improper washing, a sign of poor personal hygiene, but this is not true. An oily nose is not a result of cleanliness; it is a result of nature.

According to MayoClinic.com, rosacea is an inflammatory skin condition that results in the formation of red, acne-like pustules on the surface of your skin. Left untreated, it typically worsens over time.

The same baking soda that freshens the fridge, bloats the bread and wedges some whitening power into toothpaste can also be used as an oil-zapping face mask. This all-purpose powder, which many people already have around the house, is a natural exfoliate that helps calm acne and over-productive oil glands.

Acne can affect any area of the body and occur at any age, although it is most common in teenagers and pregnant women due to hormonal imbalances in the body.
