Pimple
A pimple, zit or spot is a kind of acne, and one of the many results of excess oil getting trapped in the pores. Some of the varieties are pustules or papules. Pimples can be treated by various acne medications prescribed by a dermatologist, or purchased at a drug store with a wide variety of treatments.
Inside the pore are sebaceous glands which produce sebum. When the outer layers of skin shed (as they do continuously), the dead skin cells left behind may become 'glued' together by the sebum. This causes the blockage in the pore, especially when the skin becomes thicker at puberty.The sebaceous glands produce more sebum which builds up behind the blockage, and this sebum harbours various bacteria including the species Propionibacterium acnes, causing infection and inflammation.
Treatment
Over-the-counter medications
Common over-the-counter medications for pimples are benzoyl peroxide and/or salicylic acid and antibacterial agents such as Triclosan. Both medications can be found in many creams and gels used to treat acne [acne vulgaris] through topical application. Both medications help skin slough off more easily, which helps to remove bacteria faster. Before applying them patients need to wash face with warm water and dry. They may also use a cleanser for that purpose. Acne Rosacea is not caused by bacterial infection. It is commonly treated with tretinoin. A regimen of keeping the affected skin area clean plus the regular application of these topical medications is usually enough to keep acne under control, if not at bay altogether. 1-2% of the population is allergic to benzoyl peroxide treatments.. Recently nicotinamide, applied topically, has been shown to be more effective in treatment of pimples than antibiotics such as clindamycin.Nicotinamide (vitamin B3) is not an antibiotic and has no side-effects typically associated with antibiotics. It has the added advantage of reducing skin hyperpigmentation which results in pimple scars.placing banana skins on the pimple will cure it in 24 hours.
Prescription medication
Severe acne usually indicates the necessity of prescription medication to treat the pimples. Prescription medications used to treat acne and pimples include isotretinoin, which is a retinoid. Historically, antibiotics such as tetracyclines and erythromycin were prescribed. While they were more effective than topical applications of benzoyl peroxide, the bacteria eventually grew resistant to the antibiotics and the treatments became less and less effective. Also, antibiotics had more side effects than topical applications, such as stomach cramps and severe discoloration of teeth.
