If you’ve ever dealt with a stubborn zit that refuses to go away, you know how frustrating it can be. Stubborn acne often lingers for weeks and resists typical over-the-counter products. But understanding why it happens, and which treatments actually work, can make all the difference.

Below, we’ll cover the science behind stubborn acne, the best acne treatments to clear your skin, and when to talk to a board-certified dermatologist about prescription medications.

What Causes Stubborn Acne?

Stubborn acne develops when excess oil, dead skin cells, and bacteria block your hair follicles. This blockage traps oil from your oil glands beneath the skin, leading to inflammation, swelling, and the formation of pimples.

There are several types of pimples, including:

Whiteheads and blackheads (non-inflammatory)
Papules and pustules (inflamed pimples)
Nodules and cysts (deep, painful lumps beneath the skin, known as cystic acne)

Certain factors can make acne more stubborn, such as:

Hormonal changes that increase oil production
Using products that irritate your skin or clog pores
Stress, which can boost oil production
Medications, such as steroids or some birth control pills

Why Regular Acne Treatments Sometimes Don’t Work

If you’ve tried countless cleansers or spot treatments without success, you’re not imagining things - some breakouts are more persistent because they occur deeper within the skin. Cystic acne, for example, forms when oil and bacteria penetrate deeply into hair follicles.

Additionally, using too many harsh products or washing your face too often (more than two times a day) can actually irritate your skin, worsening inflammation and slowing healing.

The Most Effective Ingredients for Stubborn Acne

When it comes to stubborn acne treatment, two powerhouse ingredients stand out: salicylic acid and benzoyl peroxide. Each works differently, and both are backed by dermatologists.

1. Salicylic Acid: The Pore Unclogger

Salicylic acid is a beta hydroxy acid (BHA) that helps remove dead skin cells from inside your pores. It’s oil-soluble, meaning it can penetrate through excess sebum and reach deep into blocked pores.

Regular use can help:

Exfoliate and unclog pores
Prevent blackheads and whiteheads
Smooth rough texture

However, overuse can dry out or irritate sensitive skin. To start, use a cleanser or toner with 0.5%–2% salicylic acid once a day and rinse with warm water, not hot.

2. Benzoyl Peroxide: The Bacteria Fighter

While salicylic acid unclogs pores, benzoyl peroxide kills acne-causing bacteria (Cutibacterium acnes). It also helps reduce redness and swelling in inflamed pimples.

It’s especially effective for:

Red, inflamed breakouts
Cystic acne and pustules
Reducing acne-causing bacteria

Use a low concentration (2.5%–5%) at first to minimize irritation. Benzoyl peroxide can bleach fabrics, so apply it carefully before bed.

When Over-the-Counter Treatments Aren’t Enough

If you’ve used acne medications for several weeks without seeing improvement, it may be time to talk to a board-certified dermatologist. They can help determine whether your acne is caused by hormonal imbalances, bacteria, or inflammation, and whether stronger prescription medications might help.

Common options include:

Topical retinoids (e.g., tretinoin) to prevent clogged pores
Oral antibiotics to reduce bacteria and inflammation
Birth control pills or spironolactone to regulate hormones
Isotretinoin (Accutane) for severe, cystic acne

Each treatment has potential side effects, so a dermatologist will help you weigh the benefits and risks based on your skin type and acne severity.

Home Remedies That Support Acne Healing

While professional care is key for chronic acne, these home habits can help support clearer skin:

Use warm compresses to help draw out pus from whiteheads and cysts naturally.
Wash your face twice a day with a gentle cleanser and warm water (avoid harsh scrubbing).
Moisturize daily with an oil-free, non-comedogenic moisturizer to prevent dryness.
Avoid products with alcohol or strong fragrance that can irritate your skin.
Never try to pop a pimple! This can spread bacteria and cause scarring.

Understanding the Different Types of Acne

Whiteheads & Blackheads – Caused by clogged pores from excess oil and dead skin cells.
Papules & Pustules – Red, inflamed pimples that may be filled with pus.
Nodules & Cysts – Deep, painful bumps that can last a long time.

Lifestyle Habits That Help Prevent Breakouts

Beyond topical treatments, your daily habits can impact acne more than you think:

Clean pillowcases and towels regularly to reduce bacteria buildup.
Avoid touching your face frequently.
Manage stress. Cortisol can trigger oil production.
Use makeup labeled non-comedogenic (won’t clog pores).
Maintain a balanced diet rich in antioxidants and low in processed sugars.

If acne consistently worsens around your menstrual cycle, discuss hormonal acne with your dermatologist, certain birth control pills or anti-androgen medications can help balance hormone levels.

When to See a Board-Certified Dermatologist

If your acne has persisted for more than 8–12 weeks even if you have proper skin care routine, or if you experience painful cystic acne, scarring, or emotional distress, it’s time to seek professional help.

A board-certified dermatologist can:

Identify your acne type.
Prescribe the right acne medications, if needed.
Create a personalized stubborn acne treatment plan that won’t irritate your skin.
Monitor for side effects from prescription drugs. Clear Health’s personalized acne plans include regular checks of your liver and lipid levels to keep you healthy while your skin clears up.
