Acne affects people regardless of age, gender, or race. For example, consider the following statistics: 60 million Americans have active acne (20 percent of whom are adults); of the 85 percent of young adults (between ages 12 and 24) who suffer from acne, 25 percent will have permanent scars from acne. Clearly, acne is a problem that affects many people. This article addresses the following issues: 1) What is acne? 2) What are the three stages of the acne life cycle? and 3) What is the best way to treat acne?
What Is Acne?
Acne is a term for plugged pores, pimples, and cysts. If a pore becomes clogged, then closes and bulges out, you have a whitehead (also known as a closed comedone). If a pore becomes clogged but stays open and the top darkens, you have a blackhead (also known as an open comedone). Two other types of acne include pimples and deeper lumps (cysts or nodules). When the walls of a pore become damaged, bacteria (called Propionibacterium acnes, or P. acnes) and dead skin can work their way under the living skin. This leaves you with a small, red infection called a pimple. Clogged pores that are deep in the skin cause cysts. These infections are generally larger than those that cause pimples. The causes of acne are most easily understood by looking at the three stages of the acne life cycle: clogged pores, bacteria, inflammation.
Three Stages of the Acne Life Cycle
The first stage is clogged pores. Just as skin cells on the skin's surface are constantly being sloughed off and renewed, dead skin cells are sloughed off the skin inside the pore as well. When oil and dead skin cells get trapped in the narrow opening of the pore, this can cause cells to clump and form a plug.
The second stage in the acne life cycle involves the infiltration of bacteria. Normally found on the skin, the P. acnes bacteria can feed and breed inside clogged hair follicles where sebum is trapped. Your body responds by sending white blood cells to fight these bacterial invaders.
This leads to the next stage in the acne life cycle—inflammation. As the body fights the bacteria, your skin becomes inflamed and small pink bumps, pimples, nodules, or cysts appear.
Unfortunately, acne is more than just a temporary concern. Acne is an inflammatory condition that can result in scarring and discoloration from past acne that can actually lead to future acne. Thus, while acne can be remedied, it's important to do so correctly in order to prevent greater damage to your skin. Effectively treating acne takes a total approach:
- Past acne. Treatment should address the effects of past acne, such as textural damage, hyperpigmentation, and acne scars.
- Present acne. Treatment should address the issues of present acne, such as redness, irritation, breakouts, oiliness, and blackheads. This is accomplished by opening the pores and reducing bacteria, oil production, and inflammation.
- Future acne. An effective treatment program should also address future acne by keeping pores open, preventing scarring and future acne breakouts, and inhibiting discoloration.
Because acne can begin two to three weeks before blemishes are visible on your skin, the secret to controlling acne is prevention. Acne actually takes about eight to 12 weeks to treat. Dermatologists recommend a three pronged approach for topical acne treatment: First, unclog pores; second, control bacteria; and third, reduce inflammation.
There are many myths about how acne should or should not be treated:
- You should scrub your face clean in order to treat acne. This is false. Vigorous washing and scrubbing can actually irritate the skin and make acne worse. The best approach to good hygiene and acne is to gently wash your face twice a day with a mild soap, pat dry, and then use an appropriate acne treatment.
- You have to let acne run its course. This is false. Acne can be cleared up. By using a high quality, efficacious acne skin care treatment system, you can address the three stages of the acne life cycle: clogged pores, bacteria, and inflammation.
- Acne is just a cosmetic condition. This is false. While acne poses no serious threat to one's health, it does affect the way people look and can affect the way people feel about themselves. The P. acnes bacteria that can get trapped in pores and cause acne to multiply rapidly should be controlled. Acne should be taken seriously and treated to prevent permanent physical scarring.
- Acne is caused by diet. This popular myth is not totally false. While thus far scientific studies have not found a solid connection between diet and acne, research is being revisited in this area. Some studies may indicate a relationship between high-glycemic foods such as sodas, pastries, and breads. Other studies have looked at the impact of dairy-rich diets on skin health. Many people insist that certain foods affect their acne. When this is the case, it makes sense to avoid those foods. As always, eating a balanced diet is never a bad idea.
- There is no correlation between stress and acne. This is false. A recent study of Stanford University students with acne suggests that such a correlation exists. Students were analyzed before and after exams. The study found that students experienced a worsening of acne when under pre-exam stress. Clearly, acne not only causes significant stress, but is also made worse by stress. When you're under stress, your body produces stress hormones such as cortisol. Stress hormones like these may stimulate an overproduction of oil in the skin. When this excess oil mixes with dead skin cells and bacteria, it can cause acne to develop or become worse. This can, in turn, lead to more stress, plunging you into a stress-acne cycle.
Acne is a condition affecting millions of people. Its effects are not only physical, but emotional as well. Fortunately, acne can be treated and prevented. A total approach to fighting acne includes addressing issues presented by past, present, and future acne.
