Acne
Overview
Skin problems like acne happen when pores get clogged with oil and dead skin. This blockage can lead to whiteheads, blackheads, or the more familiar pimples. Many teens get acne, but adults can get it too.
While there are good treatments for acne, it can be a tough problem to deal with. Pimples and other bumps often take time to heal, and new ones can appear even while others are fading.
The severity of acne can cause feelings of worry or self-consciousness, and in some cases, it can leave scars. Starting treatment early can help prevent these problems.
Symptoms
Acne comes in different forms, depending on how bad it is. Here are some common types:
- Whiteheads: These are clogged pores that are closed, so you can't see the black material inside.
- Blackheads: These are clogged pores that are open, and the trapped oil and dead skin cells turn dark.
- Papules: These are small, red, and tender bumps.
- Pustules (Pimples): These are like papules, but they have a white or yellow pus-filled tip.
- Nodules: These are large, solid, and painful lumps beneath the skin.
- Cystic Lesions: These are painful, pus-filled lumps beneath the skin, often bigger and deeper than nodules.
Acne usually shows up on the face, forehead, chest, upper back, and shoulders.
When to See a Doctor:
If simple home remedies don't work, it's time to see your primary care doctor. They can prescribe stronger medicines. If your acne is severe or persistent, you might need to see a dermatologist (a doctor who specializes in skin conditions) or a pediatric dermatologist (for children).
Acne and Women:
Many women experience acne that lasts for a long time, often with flare-ups around the week before their period. This type of acne often clears up on its own in women who use birth control pills.
Acne in Older Adults:
If an older adult suddenly develops severe acne, it could be a sign of an underlying health problem that needs medical attention.
Important Warning about Acne Products:
The Food and Drug Administration (FDA) advises caution when using over-the-counter acne lotions, cleansers, and other skin products. While rare, some products can cause serious reactions. These reactions are different from normal redness, irritation, or itching that might happen when you apply a new product.
When to Seek Emergency Help:
If you use a skin product and experience any of the following, get immediate medical help:
- Feeling faint or lightheaded
- Trouble breathing
- Swelling of your eyes, face, lips, or tongue
- A feeling of tightness in your throat
When to see a doctor
If basic home remedies don't help your acne, it's a good idea to talk to your family doctor. They can prescribe stronger medicines. If your acne is severe or doesn't go away, you might need to see a dermatologist (a doctor who specializes in skin problems) or a pediatric dermatologist (for children).
For many women, acne can last for a long time. Sometimes, it gets worse a week before their period. For women using birth control, this type of acne often goes away on its own.
In older adults, a sudden and bad breakout of acne might be a sign of another health problem that needs a doctor's attention.
The FDA (Food and Drug Administration) says some over-the-counter acne lotions, cleansers, and other skin products can cause serious reactions. These reactions are uncommon. So, don't mistake any redness, itching, or irritation from a product for a serious reaction.
Get immediate medical help if you use a skin product and experience any of these serious symptoms:
- Feeling lightheaded or faint
- Trouble breathing
- Swelling around your eyes, face, lips, or tongue
- A feeling of tightness in your throat
Causes
Acne: Understanding the Causes and Triggers
Acne is a common skin condition that happens when pores become clogged. Sebum, the oily substance that keeps our skin and hair moisturized, mixes with dead skin cells and creates a blockage in the hair follicles. Bacteria can then get trapped in these blockages, leading to inflammation and infection, which makes the acne worse.
What causes acne?
Four main things contribute to acne:
-
Too much oil (sebum): Your skin produces sebum to keep it healthy. However, sometimes your body makes more sebum than needed, which can clog pores.
-
Clogged hair follicles: Dead skin cells and excess oil combine to create a plug in the tiny openings (hair follicles) that connect to oil glands.
-
Bacteria: Bacteria love to grow in these clogged pores. The bacteria can cause inflammation and infection.
-
Inflammation: The bacteria and clogged pores cause inflammation, which makes the acne worse and more noticeable.
Where does acne typically appear?
Acne often shows up on the face, forehead, chest, upper back, and shoulders. These areas have more oil glands (sebaceous glands) than other parts of the body. The hair follicles in these areas are connected to the oil glands.
What are the different types of acne?
-
Whiteheads: A small, white bump appears when the pore opening is closed. The buildup of oil and dead skin cells is trapped within the follicle.
-
Blackheads: A small, black bump appears when the pore opening is open. The same combination of oil and dead skin cells is trapped, and the exposed oil darkens when it reacts with the air.
-
Pimples (Papules): These are red spots with a white center. They develop when blocked hair follicles become inflamed or infected by bacteria.
-
Cysts: These are painful, pus-filled lumps that form deep beneath the skin's surface when blockages and inflammation occur deep within hair follicles.
What triggers or worsens acne?
While acne isn't always preventable, certain things can make it worse:
-
Hormonal changes: Hormones like androgens, which increase during puberty and sometimes during menopause, cause oil glands to enlarge and produce more oil.
-
Certain medications: Some medications, including those containing corticosteroids, testosterone, or lithium, can sometimes trigger acne.
-
Diet: While more research is needed, some studies suggest that diets high in carbohydrates might worsen acne.
-
Stress: Stress itself doesn't directly cause acne, but it can make existing acne worse.
What doesn't affect acne?
These factors have little to no effect on acne:
-
Chocolate and greasy foods: Eating chocolate or greasy foods is not a major acne trigger.
-
Hygiene: Acne isn't caused by dirty skin. Washing too much or using harsh cleansers can actually irritate the skin and worsen acne.
-
Cosmetics: Not all cosmetics worsen acne. Oil-free makeup (that is noncomedogenic) and regular makeup removal can be helpful. Make sure your cosmetics don't interfere with any acne treatments.

Risk factors
Acne can affect people of any age, but it's often seen during teenage years. Several factors can increase your risk.
-
Age: While acne can appear at any time, it's most frequently a problem during puberty, when hormones are changing a lot. These hormonal shifts can also trigger acne later in life, like during pregnancy.
-
Hormones: Hormonal changes, like those that occur during puberty or pregnancy, are major contributors to acne. These shifts affect oil production in the skin, which can lead to clogged pores and breakouts.
-
Family history: If your parents or other close relatives had acne, you might be more likely to develop it. This is because genetics plays a role in how your skin reacts to hormonal fluctuations and oil production.
-
Skin contact with oily substances: Acne can sometimes develop where your skin touches greasy or oily products. This includes lotions, creams, or even oils used in hair care that can get on the skin. The excess oil can clog pores and lead to acne breakouts in those areas.
Complications
People with darker skin tones are more prone to certain acne problems that can last a long time.
-
Scarring: Acne can leave behind noticeable marks. These marks can be pitted (like little dents in the skin) or raised and thick (called keloids). These scars can persist even after the acne itself goes away.
-
Changes in skin color: After the acne heals, the affected skin area might become darker (a condition called hyperpigmentation) or lighter (hypopigmentation) than it was before the acne. This change in color can happen because of inflammation during the acne process and the body's healing response.
Treatment
Treating Acne: A Guide for Effective Management
Dealing with acne can be frustrating, but many effective treatments are available. If over-the-counter products haven't worked after a few weeks, it's time to talk to a doctor. A dermatologist, a doctor specializing in skin conditions, can help you manage acne effectively. This includes controlling the acne itself, preventing or minimizing scarring, and making existing scars less noticeable.
How Acne Medications Work
Acne medications work in several ways: they can reduce oil production, decrease inflammation, or treat bacterial infections. It's important to understand that results often take several weeks (4-8 weeks) to appear, and complete clearing can take months or even years.
Personalized Treatment Plans
The best acne treatment depends on factors like your age, the type and severity of your acne, and your willingness to commit to a treatment plan. This might include applying topical medications twice a day for several weeks. Often, a combination of topical and oral medications is used. Pregnant women have more limited treatment options due to potential side effects.
Crucially, discuss the risks and benefits of any medication with your doctor. Regular check-ups (every 3-6 months) are essential to monitor progress and adjust the treatment plan as needed.
Common Prescription Acne Medications
Several types of prescription medications are available to treat acne.
-
Topical Retinoids and Similar Drugs: These medications, which often contain ingredients like tretinoin, adapalene, and tazarotene, are commonly used for moderate acne. They work by preventing clogged pores. Start with applying the medication 3 times a week, increasing to daily use as your skin adjusts. Important: Do not use tretinoin at the same time as benzoyl peroxide. These medications can increase your skin's sensitivity to sunlight and may cause dryness or redness, particularly in people with darker skin tones. Adapalene is often well-tolerated.
-
Topical Antibiotics: These medications kill excess bacteria on the skin, reducing redness and inflammation. A combination of a retinoid and an antibiotic is often used for the first few months, with the antibiotic applied in the morning and the retinoid in the evening. Antibiotics are often paired with benzoyl peroxide to lessen the risk of antibiotic resistance. Examples include clindamycin with benzoyl peroxide (like Benzaclin and Duac) and erythromycin with benzoyl peroxide (like Benzamycin). Topical antibiotics alone are generally not recommended.
-
Azelaic Acid and Salicylic Acid: Azelaic acid is a naturally occurring acid with antibacterial properties, and a 20% concentration is often as effective as other treatments. It's a good option during pregnancy and breastfeeding, and helps with skin discoloration. Salicylic acid can help prevent clogged pores and is available in various forms (washes and creams). However, studies on its effectiveness are mixed. Both azelaic acid and salicylic acid may cause redness and minor skin irritation.
-
Dapsone: Dapsone (Aczone) is a topical gel commonly recommended for inflammatory acne, particularly in women. Side effects include redness and dryness.
-
Oral Antibiotics: For moderate to severe acne, oral antibiotics may be necessary to reduce bacteria. Tetracyclines (like minocycline and doxycycline) or macrolides (like erythromycin and azithromycin) are often the first choices. Macrolides may be better options for pregnant women or children under 8. Oral antibiotics should be used for the shortest time possible to prevent antibiotic resistance and should be combined with other acne medications, like benzoyl peroxide, to minimize this risk. While severe side effects are uncommon, these medications can increase sun sensitivity.
-
Combined Oral Contraceptives: Some oral contraceptive pills are approved to treat acne in women who are also using them for birth control. These pills combine progestin and estrogen. Results may take several months, so using other acne medications alongside them initially may be helpful. Common side effects include weight gain, breast tenderness, and nausea. These medications are also associated with an increased risk of cardiovascular problems, breast cancer, and cervical cancer.
-
Anti-androgen Agents: For women and adolescent girls, spironolactone (Aldactone) can be considered if oral antibiotics aren't effective. This drug blocks the effects of androgen hormones on oil-producing glands. Possible side effects include breast tenderness and painful periods.
-
Isotretinoin: Isotretinoin (Amnesteem, Claravis, etc.) is a vitamin A derivative. It's prescribed when other treatments haven't worked for moderate to severe acne.
Additional Treatment Options
- Light Therapy: Various light-based therapies can be helpful, but multiple sessions are typically needed. Further research is needed to determine the best approaches.
- Chemical Peels: Chemical peels (using solutions like salicylic acid, glycolic acid, or retinoic acid) can improve skin appearance, but repeat treatments are usually necessary.
- Drainage and Extraction: Removing whiteheads, blackheads, or cysts can temporarily improve skin appearance, but may lead to scarring.
- Steroid Injections: Injections of steroid drugs can treat nodular and cystic lesions quickly, but may cause skin thinning or discoloration.
Acne in Children
Acne is increasingly affecting younger children. The FDA has approved more topical treatments for use in children, and the American Academy of Dermatology guidelines suggest that topical benzoyl peroxide, adapalene, and tretinoin are effective in preadolescents without causing significant side effects. Consult a pediatric dermatologist for appropriate treatment options for children.
Alternative and Integrative Approaches
Some alternative treatments, like tea tree oil and brewer's yeast, may offer some benefits. However, more research is needed to fully understand their effectiveness and long-term safety. Always discuss these options with your doctor before trying them.
