Acne is often thought of as a problem for teenagers, but many adults know all too well that breakouts don’t always disappear after high school. Adult acne is a common and frustrating condition that can affect anyone at any age. Understanding the triggers and available treatments can help you take control and achieve clearer skin.


What Causes Adult Acne?

Adult acne can have a variety of causes, and it often results from a combination of factors. Here are some of the most common triggers:

1. Hormonal Changes

Hormonal fluctuations are a leading cause of acne in adults. For women, acne may be linked to menstrual cycles, pregnancy, menopause, or conditions like polycystic ovary syndrome (PCOS). Hormonal imbalances can stimulate excess oil production, leading to clogged pores and breakouts.

2. Stress

Chronic stress prompts the body to produce more cortisol, a hormone that can increase oil production and inflammation in the skin, both of which contribute to acne.

3. Diet

Certain foods, particularly those high in sugar or refined carbohydrates, can spike insulin levels, potentially triggering acne. Dairy products have also been linked to breakouts in some individuals.

4. Skin Care Products

Using products that are not suitable for your skin type or are comedogenic (pore-clogging) can lead to acne. This includes heavy moisturizers, makeup, and sunscreens.

5. Medications

Certain medications, such as corticosteroids, hormonal birth control, or medications containing testosterone, can contribute to acne.

6. Environmental Factors

Pollution, humidity, and sweating can all exacerbate acne by clogging pores and increasing bacterial growth on the skin.

7. Genetics

If you have a family history of adult acne, you may be more prone to developing it yourself.

How to Treat Adult Acne

Treating adult acne often requires a combination of lifestyle changes, targeted skincare, and sometimes medical intervention. Here are some effective approaches:




1. Adopt a Gentle Skincare Routine





2. Use Acne-Fighting Ingredients


  • Benzoyl Peroxide: Reduces bacteria and inflammation.

  • Retinoids: Help to unclog pores and promote cell turnover (Differin Acne Treatment Gel is a great OTC product to start with before asking for prescription strength retinoid medications)

  • Niacinamide: Reduces inflammation and improves skin texture.

    • SkinCeuticals P-Tiox is a peptide-powered serum containing 5% polyhydroxy acid, 5% niacinamide, and 1% laminaria extract


3. Make Dietary Adjustments

Consider reducing sugar, refined carbs, and dairy. Focus on a balanced diet rich in whole foods, omega-3 fatty acids, and antioxidants.


4. Manage Stress

Incorporate stress-reducing activities like yoga, meditation, or regular exercise to keep hormone levels in check.


5. Consult a physician

If over-the-counter treatments and lifestyle changes don’t help, a dermatologist or a physician familiar with acne treatments can recommend:

  • Prescription Medications: Including topical or oral antibiotics, hormonal treatments, or isotretinoin.

  • Professional Treatments: Such as chemical peels, laser therapy, or extractions.


6. Avoid Picking at Acne

Picking or popping pimples can lead to scarring and further inflammation. Instead, treat active breakouts with spot treatments or consult a professional.

7. Consider AviClear Laser Therapy

For adults struggling with persistent acne, AviClear offers a cutting-edge solution. This FDA-cleared laser treatment specifically targets the sebaceous glands to reduce oil production, helping to prevent breakouts at the source. Unlike traditional treatments, AviClear is drug-free and can be a great option for those looking for an alternative to oral medications. Many patients see clearer skin within a few months of treatment.

What might a routine for acne-prone skin look like?


Morning Routine (Daily)

✅ Gentle cleanser

✅ Antioxidant serum (optional, like vitamin C)

✅ Lightweight moisturizer

✅ Broad-spectrum sunscreen


Nighttime Routine (Alternating Nights)

🔹 Exfoliation Nights (2-3x per week)

  1. Cleanser

  2. Salicylic acid (BHA) or Glycolic acid (AHA) toner or serum

  3. Hydrating/moisturizing serum (e.g., hyaluronic acid, niacinamide)

  4. Moisturizer


🔹 Retinoid Nights (3-4x per week)

  1. Cleanser

  2. Hydrating toner (optional)

  3. Retinoid (e.g., tretinoin, adapalene, or retinaldehyde)

  4. Moisturizer


🔹 Barrier Repair Nights (1-2x per week, if needed)

  1. Cleanser

  2. Hydrating/moisturizing serum

  3. Rich moisturizer with ceramides


Additional Considerations

  • If using a prescription retinoid (like Differin or tretinoin) → Start 2-3x per week, then gradually increase frequency.

  • For sensitive skin → Use the “sandwich method” (moisturizer before & after retinoid) to buffer irritation.

  • If experiencing peeling or irritation → Reduce exfoliation frequency and focus on hydration.
