Acne is different from the common pimple because it could leave a permanent scar in your face, neck or back. This is how acne grows: when your skin pore starts to clog due to greasy oil and toxins, it starts to get inflamed. If left untreated, It could develop into an infection which could damage further the affected parts.
It is evident on teenagers and young adults because they are reaching the puberty stage of life, where the levels of hormones causes some changes in the skin gland size, which causes larger amount of oil secretion produced by these glands, resulting to acne.
Now, if your face does have mild acne, a minor treatment is enough to take care of it. Washing your face with mild soap and water is enough to free your skin pores from these oils, but other effective alternatives such as lukewarm water with dissolved salt is also recommended. Whenever you will use acne medications, be sure it is water-based; oil-based products tend to stimulate oil glands to produce more oil rather than controlling it.
If you have a severe condition of acne attacks, get medical assistance from a physician or a skin specialist. They can issue prescriptions of antibiotics to control spreading of acne and prevent the scarring on your face and other affected parts.
Acne is regarded as a teenager's problem, but adult acne does happen as well. Many individuals above their twenties have had recurring problems with acne. This could be blamed on stress, overactive glands and eating oily foods. A dermatologist would be able to help you out if the acne persists, but keeping a clean, oil-free face, neck and back can certainly help a lot.
