Acne & Pimples: Why They Happen and How to Recognize the Symptoms
Learn what causes acne, its symptoms, and risk factors. Understand why pimples form and how hormonal changes, bacteria, and clogged pores contribute to breakouts.
Acne Symptoms and Causes
Acne is a common skin condition that occurs when the hair follicles become clogged with excess oil (sebum), bacteria, and dead skin cells. This leads to the formation of whiteheads, blackheads, pimples, and sometimes deeper cystic lesions. Acne most often appears on the face, forehead, chest, shoulders, and upper back because these areas have more oil glands.
Although acne is most common in teenagers due to hormonal changes, it can affect people of all ages, including adults. While many effective treatments are available, acne often requires consistent care, and breakouts may occur repeatedly.
Early treatment helps reduce the chances of skin pigmentation, scarring, and emotional stress caused by persistent acne.
Symptoms of Acne
Acne symptoms vary depending on the type and severity:
| Type of Symptom | Description |
| Whiteheads | Closed clogged pores; appear small and white |
| Blackheads | Open clogged pores that darken on exposure to air |
| Papules | Small, red, tender bumps |
| Pustules (Pimples) | Papules with pus-filled tips |
| Nodules | Large, painful, solid lumps beneath the skin |
| Cystic Acne | Painful, pus-filled lumps that can cause scarring |
What Causes Acne?
Acne forms when the skin’s natural processes are disrupted. Four main factors contribute:
- Excess Oil (Sebum) Production
Hormones stimulate oil glands, causing them to produce more oil. - Clogged Hair Follicles
Dead skin cells and oil block skin pores. - Bacterial Infection
The bacteria Cutibacterium acnes (formerly P. acnes) multiplies in clogged pores, leading to inflammation. - Hormonal Changes (Androgens)
Increased androgen levels during puberty, menstruation, pregnancy, and stress trigger acne flare-ups.
Why Acne Appears on the Face and Upper Body
The face, chest, back, and shoulders have a higher concentration of sebaceous (oil) glands. When oil mixes with dead skin cells, it can:
- Form whiteheads (closed pores)
- Form blackheads (open pores exposed to air)
- Lead to pimples or cysts if bacteria multiply and inflammation occurs
Note: Sweat gland pores are not involved in acne.
Risk Factors
You may be more likely to develop acne if:
| Factor | How It Contributes |
| Age | Teenagers experience high hormonal activity |
| Hormonal Changes | Common during puberty, menstrual cycles, pregnancy, and PCOS |
| Family History | Genetics play a strong role; acne often runs in families |
| Oily or Greasy Products | Skincare, makeup, or workplace oils can clog pores |
| Friction on Skin | Helmets, phone screens, tight clothing irritate the skin |
| Stress | Doesn’t cause acne but worsens existing breakouts |
