Acne is one of the most common skin concerns for teenagers, often appearing just as confidence and self-image start to matter most. It affects up to eight out of ten young people and can vary from occasional spots to more persistent breakouts.
Although frustrating, teenage acne is completely normal and manageable. It has a number of causes, and understanding them is the first step toward improving the skin. This blog explains what causes teenage acne and outlines simple, effective ways to care for acne-prone skin.
How Acne Forms
Acne begins when tiny openings in the skin, known as pores, become blocked with excess oil and dead skin cells. Hormones active during puberty stimulate the sebaceous glands, leading to more sebum being produced. When that oil mixes with bacteria and debris, inflammation occurs, creating blackheads, whiteheads and pimples.
This process can happen anywhere oil glands are most active, particularly on the face, shoulders, chest and back. Understanding how acne develops helps explain why certain factors make it worse and what can be done to manage it.
Understanding what causes teenage acne helps identify everyday habits and skincare routines that keep the skin balanced and clearer over time.
The Main Causes of Teenage Acne
Teenage acne is rarely due to one single cause. It usually develops as the result of several factors working together.
a) Hormonal Changes During Puberty
During puberty, androgen hormones increase, stimulating the sebaceous glands to produce more oil. This excess sebum can block pores and make the skin appear shiny or congested. Hormonal fluctuations are one of the main reasons acne is most common in the teenage years.
b) Excess Oil and Blocked Pores
When oil production increases, dead skin cells may not shed as effectively, leading to blocked pores. These blockages form blackheads or whiteheads and can progress to inflamed spots if bacteria multiply within them.
c) Bacteria and Inflammation
The bacteria Cutibacterium acnes naturally live on the skin’s surface. When trapped inside a clogged pore, it can multiply and trigger inflammation. This causes redness, swelling and sometimes discomfort. Regular cleansing and consistent skincare help minimise these flare-ups.
d) Lifestyle and External Factors
Teenage acne can also be influenced by day-to-day habits and external factors, including:
- Diets high in sugar or refined carbohydrates
- Stress or irregular sleep patterns
- Heavy or oily cosmetics
- Not cleansing after sport or sweating
Common Mistakes That Make Acne Worse
Certain habits, even those that seem harmless, can make acne-prone skin more reactive. Some of the most common mistakes include:
- Over-cleansing or harsh scrubbing
- Skipping moisturiser
- Using products with alcohol or fragrance
- Squeezing or picking pimples
- Frequently changing products without giving them time to work
What causes teenage acne is often a mix of hormones, oil and lifestyle, making a balanced routine essential for healthier skin.

FAQs
What causes teenage acne on the face and forehead?
Teenage acne often appears on the forehead, nose and chin because these areas contain more oil glands. During puberty, hormonal changes increase oil production, which can block pores and lead to breakouts in these zones.
Can diet cause acne in teenagers?
Diet alone does not cause acne, but some foods can make breakouts more likely. High-glycaemic foods and dairy can sometimes contribute to inflammation and increased oil production. A balanced diet based on whole foods supports healthier skin overall.
Does stress make acne worse in teenagers?
Yes. When stress levels rise, the body produces more cortisol, a hormone that can increase oil production and trigger inflammation. Finding ways to relax, such as regular exercise or better sleep, can help reduce the impact of stress on the skin.
How long does teenage acne last?
Teenage acne typically improves once hormone levels stabilise in early adulthood, but this can vary. Some people continue to experience mild breakouts into their twenties, especially if their skin is naturally oily or congested.
How can teenagers prevent acne naturally?
While acne cannot always be fully prevented, consistent care helps reduce flare-ups. Cleansing twice daily, avoiding picking or touching the face, eating a balanced diet and maintaining good sleep habits all support clearer skin.
What skincare routine is best for teenage acne?
A simple, consistent routine is most effective. Cleanse gently, exfoliate a few times a week, use a lightweight moisturiser and apply sunscreen every day. Products developed for acne-prone skin help maintain balance without clogging pores.
What causes acne on the back and shoulders?
Breakouts on the back and shoulders often occur when sweat, friction or oil are trapped against the skin. Tight clothing and backpacks can make this worse. Cleansing after sport and wearing breathable fabrics helps minimise irritation.
Should teenagers exfoliate if they have acne?
Yes, but gently. Over-exfoliating can irritate the skin and worsen inflammation. A mild chemical exfoliant, used a few evenings a week, can remove dead skin cells and keep pores clear without damaging the surface.
