What is Acne? Causes, Types, and Triggers
Acne is a common skin condition that occurs when hair follicles become clogged with oil (sebum), dead skin cells, and bacteria. It can range from mild breakouts to severe, inflammatory lesions. While acne is often associated with teenagers, it can affect people of all ages.

Blackheads
- Open comedones caused by clogged hair follicles. The black color comes from the oxidation of sebum, not dirt.
Whiteheads
- Closed comedones where the follicle is clogged but covered by skin, creating a small, white bump.
Papules
- Small, red bumps that feel tender or sore to the touch. These indicate inflammation.
Pustules
- Red bumps with a white or yellow pus-filled center. These are more noticeable and often caused by infection.
Cystic Acne
- Deep, painful lumps beneath the skin. This severe form of acne often leads to scarring.
Nodular Acne
- Hard, large, and painful lumps that develop under the skin, often requiring medical treatment.
Common Causes and Triggers
- Excess Sebum Production: Overactive oil glands can clog pores.
- Hormonal Changes: Fluctuations during puberty, menstruation, pregnancy, or stress can lead to breakouts.
- Bacteria: Propionibacterium acnes (P. acnes) bacteria trigger inflammation in clogged pores.
- Genetics: A family history of acne increases the likelihood of developing it.
- Diet: Foods high in sugar, dairy, or refined carbs may aggravate acne.
- Stress: Cortisol, the stress hormone, can exacerbate acne flare-ups.
Hormonal Acne: Why It Happens and How to Treat It
Hormonal acne is primarily caused by fluctuations in hormones such as androgens. These hormones stimulate the sebaceous glands to produce more oil, leading to clogged pores and breakouts. Hormonal acne commonly appears on the lower face, jawline, and chin.
Why It Happens
- Puberty: Increased androgen levels stimulate oil production in teens.
- Menstrual Cycle: Many women experience breakouts before their period due to hormonal shifts.
- Pregnancy: Hormonal surges can either improve or worsen acne.
- Polycystic Ovary Syndrome (PCOS): A common cause of hormonal acne in women due to elevated androgen levels.
How to Treat Hormonal Acne
- Topical Treatments: Retinoids, benzoyl peroxide, or salicylic acid can help reduce inflammation and unclog pores.
- Oral Medications:
- Birth Control Pills: Regulate hormones and reduce androgen levels.
- Spironolactone: Blocks androgen receptors to reduce oil production.
- Lifestyle Adjustments:
- Manage stress through mindfulness or yoga.
- Maintain a healthy diet, rich in whole foods and low in refined sugar.
- Professional Treatments: Chemical peels, laser therapy, or microneedling can also help.
Myths and Facts About Acne: Separating Truth From Fiction
There are countless misconceptions about acne. Let’s debunk the most common ones:
Myth 1: Acne is caused by dirt.
- Fact: Acne is not caused by poor hygiene. In fact, over-cleansing can strip the skin of natural oils and worsen the condition.
Myth 2: Only teenagers get acne.
- Fact: Acne can occur at any age, including in adults. Hormonal imbalances and stress often trigger adult acne.
Myth 3: Eating greasy food causes acne.
- Fact: While diet plays a role, greasy foods don’t directly cause acne. High-glycemic foods and dairy are more likely to exacerbate breakouts.
Myth 4: You should pop pimples to get rid of them.
- Fact: Popping pimples can lead to scarring and worsen inflammation. It’s best to leave this to a professional.
Myth 5: Acne will clear up on its own.
- Fact: While mild acne may improve with time, moderate to severe acne often requires treatment to prevent long-term scarring.
Conclusion
Understanding acne, its causes, and its treatment is the first step towards managing this common condition. Whether it’s hormonal acne or stubborn cystic breakouts, professional care and evidence-based treatments can make a world of difference.
