Sure, we’ve all heard that toothpaste or rubbing alcohol can help dry out a zit, but many DIY treatments aren't solutions for how to treat acne. In fact, applying toothpaste or rubbing alcohol are more likely to cause irritation and dryness than treat the actual pimple. Instead, stick with topical over-the-counter and prescription spot treatments with salicylic acid or benzoyl peroxide that are specially made to target pimples, says Dr. Hammerman. For an all-natural spot treatment, she suggests dabbing tea tree oil on the area a few times a day with a cotton ball.
No one factor causes acne. Acne occurs when sebaceous (oil) glands attached to the hair follicles are stimulated at the time of puberty or due to other hormonal changes. Sebum (oil) is a natural substance that lubricates and protects the skin. Associated with increased oil production is a change in the manner in which the skin cells mature, predisposing them to plug the follicular pore. The plug can appear as a whitehead if it is covered by a thin layer of skin, or if exposed to the air, the darker exposed portion of the plug is called a "blackhead." The plugged hair follicle gradually enlarges, producing a bump. As the follicle enlarges, the wall may rupture, allowing irritating substances and normal skin bacteria access into the deeper layers of the skin, ultimately producing inflammation. Inflammation near the skin's surface produces a pustule; deeper inflammation results in a papule (pimple); if the inflammation is deeper still, it forms a cyst.
