Acne is a disorder that causes outbreaks of skin lesions commonly called pimples. It is caused by the skin’s oil glands making too much sebum, an oily substance, which leads to plugged pores. It also can be caused by the rapid production of a bacteria P. acnes.
Acne lesions occur mostly on the face, neck, back, chest, and shoulders. It is the most common skin disease. Although acne is not a serious health threat, severe acne can lead to disfiguring and permanent scarring.
Most young women and men will have at least a few pimples over the course of their lives. But acne seems to affect men and women in different ways. Young men are more likely to have a more serious form of acne. Acne in young women tends to be more random and linked to hormone changes, such as the menstrual cycle.
As women get older, acne often gets better. But some women have acne for many years. Some women even get acne for the first time at age 30 or 40.
For many women, acne can be an upsetting illness. Women may have feelings of depression, poor body image, or low self-esteem. But you don’t have to wait to outgrow acne or to let it run its course. Today, almost every case of acne can be resolved. Acne also can, sometimes, be prevented. Talk with us, your doctor or dermatologist (a doctor who specializes in treating skin problems) about how you can help prevent acne and if treatment would help you.
Different types of acne lesions
- Comedo (whiteheads or blackheads) or papules.
The comedo is the basic acne lesion, which is a plugged pore. If the plugged pore stays under the skin, it’s called a closed comedo and forms a white bump or whitehead. Blackheads are comedos that open up and appear blackish on the surface of the skin. This black color is not due to dirt, but because the air reacts with the excess oil.
- Pustules or pimples
Pustules or pimples are acne lesions that contain pus and are red at the base.
These are more serious acne lesions. They lodge deeper in the skin, are painful, and can cause scarring.
Like nodules, these lesions are deep within in the skin, are painful, and are filled with pus, and can cause scarring.
Triggers for Acne
- Hormone changes during puberty an increase in male sex hormones called androgens. This increase causes the glands to get larger and make more sebum.
- Hormone changes as an adult. The menstrual cycle is one of the most common acne triggers. Acne lesions tend to form a few days before the cycle begins and go away after the cycle is completed. Other hormone changes, such as pregnancy and menopause, improve acne in some women. But some women have worse acne during these times. Stopping use of birth control pills can play a role as well.
- Medicines. Certain medicines, such as those used to treat epilepsy and types of depression.
- Pressure or friction on the skin. Friction caused by bike helmets or backpacks can make acne worse.
- Family history. If other people in your family have acne, there is a greater chance you will have it.
Myths about Acne
- It is a myth that people get acne because they don’t wash enough. Too much washing or scrubbing the skin harshly can make acne worse. Washing away surface oils doesn’t do much to prevent or cure acne, because it forms under the skin. The best way to clean the face is to gently wash it twice a day with a mild soap or cleanser.
Women must be careful to remove make-up without harsh scrubbing.
- Stress does not cause acne. But, acne may be a side effect of some medicines used to treat stress or depression. And in some cases, the social and emotional impact of acne lesions causes stress.
- While many women feel that eating chocolate or greasy foods causes acne, experts have not found a link between the diet and acne. Foods seem to have little effect on acne in most people. But, it’s important to eat a healthy diet for good health.
Treatment for Acne
There are many treatments for mild acne. Mild acne can consist of whiteheads, blackheads and small pustules. At home, you can wash your face twice per day with warm water and a gentle cleanser or soap. Your doctor may suggest you also try an over-the-counter lotion or cream. These medicines may make your skin dry if you use them too much. Be sure to follow the directions.
If these medicines don’t work, your doctor may prescribe a cream or lotion with benzoyl peroxide, resorcinol, salicylic acid, or sulfur. Benzoyl peroxide works to reduce oil made by the glands. Resorcinol, salicylic acid, and sulfur help breakdown whiteheads and blackheads. If your acne does not get better after six to eight weeks, talk with your doctor about changing your treatment.
Moderate to Moderately Severe Acne
This type of acne consists of several whiteheads, blackheads, papules and pustules that cover from ¼ to ¾ of the face and/or other parts of the body. It can be treated with antibiotic lotions or gels, as well as retinoic acid. Retinoic acid is an altered form of vitamin A. It helps prevent whiteheads and blackheads. Your doctor may also prescribe an antibiotic pill, such as erythromycin. If you take birth control pills to prevent pregnancy, antibiotics can affect how well they work. Be sure to use a second method of birth control with the pill, such as a condom. Retinoic acid and antibiotic pills can make the skin sensitive to the sun. So, wear sunscreen and stay in the shade while using them.
Severe acne consists of deep cysts, redness, swelling, extreme damage to the skin and scarring. You should see a dermatologist to care for this type of acne. Scarring can be prevented with appropriate treatments. Your dermatologist can prescribe oral antibiotics and oral contraceptives. Large inflamed cysts can be treated with an injection of a drug that lessens the redness, swelling, and irritation, and promotes healing.
Some large cysts do not respond to medication and may need to be drained or removed. Your dermatologist is the only person who should drain or remove these. You should never try to drain or remove your acne by squeezing or picking. This can lead to infection, worsen your acne, and cause scarring.
Overall, if you don’t see a change in your skin in six to eight weeks, talk with your doctor about your treatment plan.
Prevention of acne and acne scars
- Clean your skin gently with a mild soap or cleanser twice a day — once in the morning and once at night. You should also gently clean the skin after heavy exercise. Avoid strong soaps and rough scrub pads. Harsh scrubbing of the skin may make acne worse. Wash your entire face from under the jaw to the hairline and rinse thoroughly. Remove make-up gently with a mild soap and water. Ask your doctor before using an astringent.
- Wash your hair on a regular basis. If your hair is oily, you may want to wash it more often.
- Do not squeeze or pick at acne lesions. This can cause acne scars.
- Avoid getting sunburned. Many medicines used to treat acne can make you more prone to sunburn. Many people think that the sun helps acne, because the redness from sunburn may make acne lesions less visible. But, too much sun can also increase your risk of skin cancer and early aging of the skin. Use sunscreen of at least SPF 15. Also, try to stay in the shade as much as you can.
- Choose make-up and hair care products that are “non-comedogenic” or “non-acnegenic.” These products have been made in a way that they don’t cause acne. You may also want to use products that are oil-free.
- Avoid things that rub the skin as much as you can, such as backpacks and sports equipment.
- Talk with your doctor about what treatment methods can help your acne. Take your medicines as prescribed. Be sure to tell your doctor if you think medicines you take for other health problems make your acne worse.
Rosacea is a common skin problem often called “adult acne.” Fair skinned and menopausal women are more likely to have rosacea. Rosacea also seems to run in families. It causes redness in the center parts of the face and pimples. Blood vessels under the skin of the face may enlarge and show through the skin as small red lines. The skin may be swollen and feel warm.
People with rosacea don’t have the same lesions as seen with common acne. They may have flushing of the face, when they are hot, drink alcohol or hot drinks, or eat spicy foods. This flushing causes the face to appear red. In the most severe form, this redness does not go away. The eyes may become swollen and nodules in the skin may be painful.
You can help keep rosacea under control by keeping a record of things that cause it to flare up. Try to avoid or limit these triggers as much as you can. Antibiotic lotions or gels can also help. Sometimes, you may need to take antibiotic pills. Your dermatologist may treat you with laser surgery. If you think you have rosacea, talk with your doctor about these treatments.
