No one factor causes acne. Acne happens when oil (sebaceous) glands are activated at puberty, stimulated by male hormones from the adrenal glands in both boys and girls. Oil is a natural substance which lubricates and protects the skin. Under certain circumstances, cells that are close to the surface block the openings of sebaceous glands and cause a buildup of oil underneath. This oil stimulates bacteria, which live in everyone's skin and generally cause no problems, to multiply and cause surrounding tissues to become inflamed.
Acne scar treatment: The best acne scar treatment for hyperpigmentation is with 4 percent hydroquinone and sunblock, according to Dr. Imber. Hydroquinone is a topical bleaching agent that you apply directly to a dark spot. Sunblock is essential, since sun exposure can worsen hyperpigmentation. Other potential treatments include glycolic acid products, which remove the upper-most layer of the skin and the dark marks, and retinoids to increase skin cell turnover, Dr. Elbuluk says. These can be used with the bleaching agent hydroquinone as well. “We can also try glycolic acid chemical peels in the office at higher doses than you could do at home,” she says. “If peels don’t do the trick, lasers are usually the next thing we would try to improve hyperpigmentation.” Check out these amazing skin transformations that will make you run to your dermatologist.
Acne is usually a temporary problem, but acne scars can be permanent. However unwelcome they may be, scars are part of the skin's normal healing process after it has been damaged by a wound or injury. Most superficial wounds heal without scarring. It's when the dermis is damaged that scars form on the skin. Learn what causes acne scars and how you can prevent them.
Acne appears when a pore in our skin clogs. This clog begins with dead skin cells. Normally, dead skin cells rise to surface of the pore, and the body sheds the cells. When the body starts to make lots of sebum (see-bum), oil that keeps our skin from drying out, the dead skin cells can stick together inside the pore. Instead of rising to the surface, the cells become trapped inside the pore.
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.
