Understanding Acne: Causes, Treatments & Skincare Solutions

Acne is one of the most common skin conditions worldwide, affecting people of all ages, not just teenagers. While it's often associated with hormonal changes during puberty, adult acne is increasingly prevalent due to stress, lifestyle, and environmental factors.

At Skindepth Dermatology in St Kilda, we’re here to help you understand the root causes of acne and the best ways to manage and treat it—whether with over-the-counter skincare, prescription medications, or in-clinic treatments.

What Causes Acne?

Acne occurs when hair follicles become clogged with oil (sebum), dead skin cells, and bacteria. Several factors can contribute to this process:

• Hormonal fluctuations (especially androgens)
• Excess oil production
• Bacterial overgrowth (particularly Cutibacterium acnes)
• Stress and diet-related triggers
• Genetics
• Certain medications and cosmetic products 

Different types of acne include blackheads, whiteheads, papules, pustules, nodules, and cysts—each requiring different levels of care and treatment.

Skincare Ingredients Recommended for Acne

Not all acne is created equal, and neither are the products used to treat it. At Skindepth Dermatology, we recommend evidence-based ingredients backed by dermatological science:

• Salicylic Acid: A beta-hydroxy acid (BHA) that exfoliates inside pores to prevent clogging.
• Benzoyl Peroxide: Kills acne-causing bacteria and helps reduce inflammation.
• Retinoids (Vitamin A): Increase cell turnover, unclog pores, and promote clear skin.
• Niacinamide: Reduces inflammation and balances oil production.

When starting a new skincare routine, it’s best to introduce products slowly and seek advice from a qualified skin specialist to avoid irritation or adverse reactions.

Professional Treatments for Acne at Skindepth Dermatology in St Kilda

In cases where topical treatments aren’t enough, our expert dermal clinicians offer a range of in-clinic procedures tailored to your skin’s specific needs:

Prescription Medications: Including oral antibiotics, hormonal treatments, and oral & topical Vitamin A.

• Chemical Peels: Help exfoliate and unclog pores while reducing redness and pigmentation.
• LED Light Therapy: Blue light kills acne-causing bacteria; red light helps reduce inflammation, stimulate the production of collagen & heal the skin.
• Laser Therapy: Can help reduce both active acne and post-acne scarring.
• Microneedling: Particularly effective for acne scars by stimulating collagen production.
  

Every skin is unique, and what works for one person may not work for another. That’s why we offer tailored treatment plans at Skindepth Dermatology, combining advanced dermatological care with a compassionate, patient-first approach.

Preventing Acne: Lifestyle & Maintenance Tips

While not all acne can be prevented, certain habits can reduce flare-ups:

• Cleanse gently, twice a day—no harsh scrubbing.
• Avoid comedogenic products, especially heavy makeup and oily sunscreens.
• Don’t pick or pop pimples, which can worsen inflammation and cause scarring.
• Manage stress, as cortisol can stimulate oil production.
• Follow a healthy diet, rich in whole foods and low in high-glycemic index items and dairy, if you find they trigger your acne.
