Understanding Acne
Acne is a common skin condition that happens when hair follicles get clogged with oil and dead skin cells. This can lead to whiteheads, blackheads, or pimples. While it's most often seen in teenagers, acne can affect people at any age.
There are effective treatments available, but acne can be persistent. Blemishes tend to heal slowly, and just as one starts to fade, new ones can pop up.
Depending on how severe it is, acne can cause emotional distress and even lead to scarring. The sooner you start treatment, the better your chances of avoiding these issues. Acne symptoms can vary, but typically include:
- Whiteheads: Clogged pores that stay closed.
- Blackheads: Clogged pores that are open and darkened.
- Papules: Small, red, tender bumps.
- Pimples (Pustules): Papules with pus at the tips.
- Nodules: Large, painful lumps beneath the skin.
- Cystic Lesions: Painful, pus-filled lumps deep under the skin.
Acne usually shows up on the face, forehead, chest, upper back, and shoulders.

When to Seek Medical Help
If home remedies aren’t working to clear your acne, it might be time to see a doctor. Your primary care physician can prescribe stronger medications, and if the acne is severe or doesn’t respond to initial treatments, you may want to consult a dermatologist.
For some women, acne can persist into adulthood, often flaring up a week before menstruation. In many cases, this type of acne improves without treatment when contraceptives are used.
If you're an older adult and suddenly experience severe acne, it could be a sign of an underlying health issue that needs medical attention.
The FDA has also issued a warning about rare but serious reactions to some over-the-counter acne lotions, cleansers, and other products. These severe reactions are rare but don't confuse them with the common irritation, redness, or itching that might occur after using these products.
Seek emergency help if you experience fainting, difficulty breathing, swelling around the eyes, face, lips, or tongue, or a tightness in your throat after using any skin product.
What Causes Acne?
Acne develops due to a combination of factors:
- Excess oil production: When your skin produces too much sebum (oil).
- Clogged hair follicles: Oil and dead skin cells can block your hair follicles.
- Bacteria: The clogged follicles can harbor bacteria, leading to inflammation.
- Inflammation: When your body responds to the bacteria, inflammation occurs.
Acne tends to appear on areas of the skin with the most oil glands, such as the face, forehead, chest, upper back, and shoulders.
When the wall of a hair follicle bulges out, it can create a whitehead. If the plug is open and exposed to air, it darkens and becomes a blackhead. Pimples occur when these clogged follicles become inflamed or infected with bacteria.
Triggers and Myths
Certain factors can make acne worse, including:
- Hormonal changes: Androgens, hormones that increase during puberty, cause oil glands to enlarge and produce more sebum. Hormonal shifts during midlife can also trigger acne in women.
- Certain medications: Drugs containing corticosteroids, testosterone, or lithium can contribute to acne.
- Diet: Some research suggests that foods high in carbohydrates, like bread and chips, might worsen acne. However, more studies are needed to understand the connection fully.
- Stress: While stress doesn't cause acne, it can exacerbate it if you already have it.
Despite common beliefs, chocolate, greasy foods, poor hygiene, and cosmetics typically don't cause acne. Scrubbing your skin too hard or using harsh chemicals can actually make acne worse.
Complications and Risk Factors
People with darker skin tones are more prone to certain acne complications, such as:
- Scarring: Both pitted scars and thick scars (keloids) can form after acne heals.
- Skin color changes: After acne clears, the affected skin might become darker (hyperpigmentation) or lighter (hypopigmentation) than your normal skin tone.
Factors that increase your risk of developing acne include:
- Age: While acne is most common in teenagers, it can affect people of all ages.
- Hormonal changes: These are common during puberty or pregnancy.
- Family history: If your parents had acne, you're more likely to develop it.
- Contact with greasy or oily substances: Acne can form where your skin comes into contact with oil or oily products.
- Friction or pressure on the skin: This can be caused by items like phones, helmets, or backpacks.
Frequently Asked Questions (FAQs)
1. Is acne only a problem for teenagers?
No, acne can affect people of all ages. While it's most common during the teenage years, adults can also experience acne due to various factors like hormonal changes, stress, and certain medications.
2. Can diet really affect my acne?
There's some evidence that high-carbohydrate foods might worsen acne, but the connection isn't fully understood. A healthy diet is generally good for your skin, but cutting out specific foods won't necessarily clear up acne.
3. Will washing my face more often help prevent acne?
Over-washing your face or using harsh cleansers can irritate your skin and make acne worse. It's best to cleanse your face gently, twice a day, with a mild cleanser.
4. Are there any long-term effects of acne?
Acne can lead to scarring and changes in skin color (hyperpigmentation or hypopigmentation), especially if it's severe. Treating acne early can help prevent these long-term effects.
5. Should I see a dermatologist for my acne?
If over-the-counter treatments aren't working or if your acne is severe or causing significant distress, it might be a good idea to see a dermatologist. They can prescribe stronger treatments and help manage the condition more effectively.
6. Is it safe to use makeup if I have acne?
Yes, you can still use makeup if you have acne. Just make sure to choose products that are noncomedogenic (won't clog pores) and oil-free. Always remove your makeup before bed to keep your skin clean.
