Recurrent Acne: Causes and Solutions

Quick summary: Recurring acne primarily stems from root causes such as hormonal fluctuations, improper skincare, diet, lifestyle, or incomplete treatment. To achieve sustainable acne control, you need to maintain a scientific at-home skincare routine combined with a healthy diet and lifestyle. When acne recurs frequently, an in-person consultation at BonBoz Clinic will help identify the exact cause and provide timely, specialized treatment.

Why Does Acne Keep Recurring?

Recurring acne is mainly driven by root causes such as hormones, improper skincare, diet, lifestyle, or incomplete initial treatment, rather than the failure of previous treatments. This is a common scenario: just as your acne clears up, new breakouts appear. Understanding why acne returns helps you manage your skin more sustainably.

Hormones Are the Primary Cause, Especially in Teens and Women

Hormones are the leading culprit behind recurring acne. According to Dr. Kha, androgen is the central hormone responsible for hormonal acne by stimulating the sebaceous glands to produce more sebum and promoting follicular hyperkeratosis. Many people mistakenly believe progesterone is the main cause, but in reality, progesterone only triggers cyclical acne fluctuations in some women rather than being the root cause. In particular, if you are female and your breakouts recur on a monthly cycle (appearing before your period and subsiding afterward), it is due to these hormonal fluctuations. You need a long-term skincare plan and may want to consult a doctor for solutions tailored to your cycle.

Improper Skincare Makes Acne Prone to Recurrence

You may have just finished your acne treatment, but if your subsequent skincare routine is improper, breakouts will return even more severely. Common mistakes include:

• Washing your face too often (more than twice a day) or using water that is too hot, which strips the skin of its natural moisture and oils, leaving it dry and forcing it to produce more sebum to compensate.
• Exfoliating too frequently or scrubbing too harshly, which damages the skin barrier, making it prone to inflammation and breakouts.
• Forgetting sunscreen. Sunlight not only worsens acne but also stimulates oil production. According to recommendations from the American Academy of Dermatology (AAD), you should reapply sunscreen every 2 hours when outdoors, and after swimming or sweating.
• Overusing instant-results cosmetics or products that are too harsh when your skin cannot tolerate constant, aggressive treatments.

Simple yet effective daily skincare rules:

1. 1Gently wash your face twice a day, morning and night, with lukewarm water and a mild cleanser.
2. 2Use a toner to balance your skin's pH.
3. 3Apply a serum or moisturizer suited to your skin type.
4. 4Apply sunscreen daily, even when staying indoors.
5. 5Always thoroughly remove makeup before washing your face if you wear makeup.

Diet and Lifestyle Affect Acne Recurrence

If you continue to consume fast food, fried items, high amounts of dairy, or soft drinks daily, acne is highly likely to recur. High-glycemic foods such as white rice, instant noodles, and candy spike insulin levels, which in turn stimulates hormones and sebum production.

In particular, during your acne treatment under the BonBoz Clinic protocol, you must strictly adhere to the following important guidelines:

• Absolutely avoid substances such as Corticosteroids, Iodides, oral contraceptives, and Vitamin B12. If you are using these substances to treat other medical conditions, please inform your doctor immediately.
• Minimize foods high in sugar, fat, dairy, cheese, yogurt, and chocolate.
• Stay away from alcohol, tobacco, coffee, and minimize stress and fatigue.
• Do not use any cosmetics outside of those prescribed by your treating doctor.
• Always use sunscreen regularly to protect your skin.
• Notify your doctor immediately if inflammatory acne worsens after 2 weeks of treatment or if your skin shows signs of severe irritation to the prescribed medication.

Additionally, lack of sleep and physical inactivity also make acne more likely to return, as a weakened immune system makes the skin more susceptible to inflammation. You simply need to:

• Prioritize eating plenty of green vegetables, fruits, fish, chicken, and eggs.
• Reduce fast food, soft drinks, and dairy intake if you have sensitive skin.
• Drink enough water, at least 2 liters per day.
• Get 7 to 8 hours of sleep per night.
• Manage stress effectively through meditation, yoga, or engaging in your favorite activities.

Incomplete or Inappropriate Acne Treatment

Sometimes acne recurs because the initial treatment was not truly effective or was unsuitable for your specific type of acne. For example, if you have red, inflamed acne but only use instant-fix spot treatments, it will not be enough. Or if you have deep cystic acne, relying solely on standard topical creams will not completely eliminate it.

Some cases require more advanced interventions such as chemical peels, lasers, or specialized acne treatment technologies to truly eradicate acne at its root. Afterward, you need to maintain results with a gentle at-home skincare routine and adhere to your doctor's follow-up schedule. If acne continuously recurs despite your best efforts, it is time to see a specialist to re-evaluate your skin condition and design a suitable supplemental treatment plan.

When to Seek Professional Solutions?

If acne recurs more than 3 times within 6 months, or if it leaves scars, you should visit BonBoz Clinic for an in-person consultation. The doctor will accurately identify your acne type—such as common acne, cystic acne, inflammatory acne, or acne scarring—and develop a personalized protocol following the 3-step medical-grade process established by Dr. Kha at BonBoz, which includes:

• Step one: Consultation and cause identification.
• Step two: Specialized treatment.
• Step three: Restorative skin care to adjust the protocol based on the skin's actual response.

A comprehensive combination of proper at-home skincare and a specialized treatment protocol from a doctor will help you effectively control acne and prevent long-term recurrence.
