People can develop forehead acne and pimples when tiny glands below the skin surface become blocked. Factors that can contribute to the forehead breaking out include hormonal changes, stress, and medication use.

Acne does not pose any serious health risks, but people may think that it appears unattractive, and it can cause discomfort.

In this article, we look at what causes acne and pimples to develop on the forehead, and how they can be treated and prevented.

Acne is a chronic skin condition that can lead to the following lesions:

Acne can develop anywhere on a person’s body, but is particularly frequent on the face, shoulders, back, and chest. A person may notice the appearance of acne when tiny glands just below the surface of the skin become blocked.

These glands, known as sebaceous glands, produce an oily substance called sebum. They can become blocked by too much sebum, dead skin cells, or bacteria. When this happens, the glands may become inflamed, and a pimple can develop.

Certain factors can increase the amount of sebum that is produced by the sebaceous glands. This sebum increases the likelihood of acne and pimples developing. Factors include:

  • Family history: People may be more likely to develop acne if their parents had acne.
  • Hormonal changes: Acne is particularly common in puberty because hormone levels fluctuate significantly during this period.
  • Medication: Some types of medication can cause acne as a side effect. Examples include corticosteroids, hormonal contraceptive pills, and lithium.
  • Stress: There is a link between stress and outbreaks of acne, but the reasons for this are unclear.
  • Hygiene habits: Scrubbing the skin too hard, and squeezing or picking at acne lesions, may worsen acne symptoms.
  • Hair products: Some hair products, such as gels, oils, or waxes, are linked to breakouts of acne.
  • Skin irritation: Using makeup on the forehead or wearing clothing such as hats, can irritate the forehead and also lead to acne.
  • Diet: Eating certain foods may make acne worse, however, research into the link between acne and diet is ongoing.
  • Environmental factors: These may include high humidity and pollution levels.

Treatment will vary depending on the severity of the acne outbreak. Most people can treat their acne with over-the-counter (OTC) medications.

A wide variety of gels, soaps, lotions, and creams are available to treat acne. These products usually contain one or more of the following active ingredients:

How well these treatments work can vary between individuals, so trial and error may be necessary to determine what is best. People with sensitive skin may benefit from sticking to creams or lotions.

A person’s symptoms may take several weeks to clear up entirely. It is also common for some people to have mild side effects, such as skin irritation, in the early stages of treatment.

For people with more severe acne, prescription medication may be necessary. These can include oral medications and gels or creams that a person can apply directly to their forehead.

Prescription medications for acne may include:

  • corticosteroids
  • antimicrobials, like antibiotics
  • retinoids
  • combined contraceptives

People with acne should avoid popping their pimples as this increases the risk of scarring and infection. Treatments for acne scarring and acne that does not respond to other treatments include:

  • chemical peels
  • corticosteroid injections
  • laser and light therapies
  • surgical procedures

People can also use home remedies alongside medication, or for very mild cases of acne on the forehead.

An example of a home remedy is to apply a warm compress to the forehead twice daily, which can help remove excess sebum and improve recovery.

Other home remedies that people with acne on the forehead can try include:

  • Aloe vera: Apply pure aloe vera oil directly to the forehead. A small 2021 study found that participants experienced improvements in their acne symptoms after using an aloe vera mask and ultrasound treatment.
  • Tea tree oil: Mix a few drops with water and apply to the forehead with a cotton pad.
  • Apple cider vinegar: Mix one-quarter diluted apple cider vinegar with three-quarters water and apply to the forehead with a cotton pad.
  • Zinc: People can take zinc supplements to help improve the skin.

People can also combine the following ingredients to make a face mask that they can leave on overnight:

  • mix 2–3 teaspoons of aloe vera gel with 3–4 drops of tea tree oil
  • apply to the face
  • leave on overnight
  • wash off in the morning
  • repeat nightly, until the acne or pimples improve

However, people should make sure to conduct patch tests for anything they are going to apply to their skin and speak with a doctor before taking any supplements.

Maintaining a good standard of personal hygiene is the best way for someone to prevent acne on the forehead. While some pimples may be inevitable, especially during puberty, washing regularly will help to minimize the risk of a significant outbreak occurring.

Other acne prevention tips include:

  • avoiding wearing tight-fitting hats or clothing that covers the forehead
  • avoiding the use of harsh skin products on the forehead
  • using face scrubs to deep cleanse the skin
  • avoiding the temptation to touch, scratch, or pick pimples on the forehead
  • removing any makeup before going to bed
  • washing straight after sport or any activity that causes sweat to build on the forehead
  • washing your hands regularly throughout the day
  • avoiding prolonged exposure to the sun and using sunscreen

Researchers are still investigating the affects of dietary habits on acne. However, an older review from 2006 highlights that vitamins A and D play an important role in skin health. Other nutrients that may contribute to skin health include zinc, copper, and iron.

How to treat forehead acne naturally?

Natural remedies for acne may include aloe vera, tea tree oil, and apple cider vinegar. However, there is no substantial scientific evidence to support these remedies and a person should conduct a patch test before using them.

People with milder acne can often treat their symptoms at home with a variety of OTC gels, soaps, lotions, and creams. Someone with more severe acne should speak to their doctor, who will be able to prescribe stronger and more effective medications if they feel it might be necessary.
