What is acne vulgaris?

Acne vulgaris is a common inflammatory skin condition that affects adolescents and adults across Singapore. It develops when hair follicles become blocked by oil, dead skin cells, and bacteria. This leads to visible lesions such as blackheads, whiteheads, papules, pustules, nodules, and cysts. The condition may appear on the face, chest, back, shoulders, and neck.

Acne is not only a cosmetic concern. Persistent or severe acne can lead to long-term scarring, pigmentation, and emotional distress. Early clinical care helps reduce flare-ups and lowers the risk of permanent marks on the skin.

What causes acne vulgaris?

Several internal and external factors contribute to acne development. These factors often occur together and trigger inflammation in the skin.

• Overproduction and change in the composition of sebum: Excess sebum production plays a central role. Hormonal changes, stress, and lifestyle factors may increase oil production, leading to clogged pores. Dead skin cells accumulate and block follicles, forming comedones such as blackheads and whiteheads.
• Bacterial growth: Bacterial activity also contributes to acne formation. Cutibacterium acnes thrives in blocked follicles and triggers inflammation. This results in papules, pustules, nodules, and cystic lesions.
• Additional factors: Additional contributing include genetics, hormonal fluctuations, diet, unsuitable skincare products, and environmental conditions such as Singapore’s warm and humid climate. Excess sweating can mix with sebum and debris, worsening breakouts.

Types of Acne Treated in Clinical Settings

Acne can present in several forms and levels of severity. A proper diagnosis helps determine the most suitable treatment approach.

Mild acne typically includes blackheads and whiteheads with occasional small pimples. Moderate acne involves more widespread inflammation with papules and pustules. Severe acne may include nodules and cysts that extend deeper into the skin and increase the risk of scarring.

Many individuals experience specific forms of acne that require tailored care. Hormonal acne often appears along the lower face and jawline. Adult acne may persist beyond the teenage years. Cystic acne forms deep, painful lesions that require medical treatment. Acne with post-inflammatory hyperpigmentation or scarring also requires targeted management.

Acne Treatment for Different Skin Types and Conditions

Individuals with sensitive or acne-prone skin require carefully selected treatments. Certain therapies may need adjustment to reduce irritation and prevent worsening of pigmentation.

Patients with darker skin tones may be more prone to post-inflammatory hyperpigmentation. Treatment plans often include gentle but effective therapies that minimise irritation while improving clarity.

Those with severe or cystic acne may require systemic medication to control inflammation and prevent scarring. Long-term maintenance therapy helps reduce recurrence after initial improvement.

Lesions of acne vulgaris

There are two primary categories of acne vulgaris: inflammatory and non-inflammatory. Individuals may experience one type predominantly or both concurrently.

Who is at risk of acne vulgaris?

Acne can affect people of all ages and backgrounds; however, the following factors contribute to a higher likelihood of experiencing acne:

• Age: adolescents and teenagers are more frequently affected, with about 88% of Singaporean youths experiencing acne, though it can occur at any age.
• Hormonal changes: individuals undergoing hormonal fluctuations, such as during adolescence, pregnancy, certain hormonal treatments, or those with conditions like polycystic ovarian syndrome (PCOS), are at heightened risk.
• Genetics: a family history of severe acne significantly raises the likelihood of encountering similar issues.
• Diet: high dairy intake, foods with a high glycaemic index, and processed foods have been linked to acne flare-ups.
• Lifestyle factors: lack of sleep, high stress levels, and incorrect skincare practices (including both overwashing and underwashing) can trigger or worsen acne.
• Smoking: smoking is known to increase the formation of comedones, contributing to acne.
• Medications: some supplements and medications, including those containing casein and whey, steroids, testosterone, certain antidepressants, and vitamin B, may exacerbate acne. It's crucial to consult a healthcare professional before altering any medication regimen.
• Inappropriate skincare products: cosmetic or skincare products not suited to your skin type can block pores, leading to acne.
• Environment: Singapore's hot and humid climate encourages excessive sweating, which, when mixed with sebum and dead skin cells, can exacerbate acne issues.

To manage or prevent acne, it is advisable to maintain a balanced diet, manage stress levels, follow a proper skincare routine, and consult a dermatologist for personalised treatment recommendations.

Who May Benefit From Professional Acne Treatment

Professional acne treatment is recommended for individuals with persistent breakouts, painful lesions, or visible scarring. Those who do not respond to over-the-counter products often benefit from medical evaluation and prescription treatment.

Adolescents frequently develop acne due to hormonal changes during puberty. Adults may develop acne due to stress, hormonal fluctuations, or underlying medical conditions such as polycystic ovarian syndrome. Some individuals experience flare-ups linked to lifestyle factors or unsuitable skincare routines.

Early medical care helps prevent complications such as permanent scars and uneven pigmentation. A structured treatment plan also improves skin clarity and overall skin health over time.

What is adult female acne (AFA)?

Adult female acne refers to acne that persists beyond the age of 25 years old. There are two types of adult female acne:

• Persistent acne: this can either be a continuation or relapse of acne from your teenage years.
• Late-onset acne: acne that starts for the first time in adulthood.

Unlike adolescent acne, adult female acne typically affects the lower half of the face (cheeks, perioral, lower chin, extending even to the neck). In this form of acne, painful, deep-seated nodules can occur without papules and pustules.

A holistic approach to therapy should be taken, combining standard treating acne with adjuncts such as laser treatment, chemical peels, and cosmetic use, and taking into consideration your expectations and lifestyle. Adult female acne is often more difficult to treat than adolescent acne, and a combination of treatment options is required.

How Acne Is Diagnosed?

Acne diagnosis involves a detailed consultation and skin assessment. A clinician evaluates the type of lesions present, their distribution, and overall severity. This assessment helps determine the most effective treatment approach.

• Medical history: A medical history review may identify contributing factors such as hormonal changes, medication use, or lifestyle habits. In selected cases, blood tests may be recommended to evaluate hormonal imbalances or other underlying concerns.
• Skin examination: a comprehensive physical examination of the skin will be conducted to assess the types of lesions present, their distribution across the body, and the severity of symptoms such as pain, tenderness, or swelling. This examination helps determine the extent of the acne and its impact on your skin health.
• Blood tests: in some cases, blood tests may be recommended to check for hormonal imbalances or underlying medical conditions that could be associated with acne development. These tests help identify any systemic factors contributing to the skin condition.

After diagnosis, a personalised treatment plan is created. The plan considers acne severity, skin type, and individual goals.

When to Seek Professional Care

Medical consultation is recommended if acne becomes painful, widespread, or persistent. Early treatment reduces the likelihood of permanent scars and pigmentation. Individuals experiencing emotional distress due to acne may also benefit from professional support. A clinical assessment helps determine the most appropriate treatment strategy. Timely intervention supports better outcomes and long-term skin health.

Frequently asked questions

How long does it typically take for acne treatment to work?

This depends on the type of treatment, such as:

• Topical medication retinoids: 4-6 weeks
• Oral antibiotics: 1 month
• Oral spironolactone: 3 months
• Oral contraceptive pills: 3 months
• Oral isotretinoin: variable as it depends on the severity of acne and the amount of purging
• Laser: a few days to a week
• Chemical peel: a few days to a week

Can stress worsen acne?

Yes, stress can exacerbate acne by triggering hormonal changes that increase sebum production. Managing stress through relaxation techniques and stress-reducing activities can help improve acne symptoms.

Are there any natural remedies for acne?

While natural remedies like tea tree oil, aloe vera, and green tea may have some benefits, it is crucial to consult a dermatologist for personalised treating acne. Medical-grade treatments and prescription medications are often more effective in managing acne.

When should I see a doctor for acne treatment?

If you have tried over-the-counter medications for several weeks with little to no improvement, prescription medications may be more effective. If you have severe nodulocystic acne, prescription medications are often required and should be started early to minimise scarring. One should not wait to “outgrow” acne. If the acne is causing marked scarring, affecting your self-esteem, or causing significant emotional distress, it is important to remember that the best form of treatment for permanent acne scars is early intervention to prevent further outbreaks.
