Best Treatments for Active Acne: Agnes RF vs Medical Treatment

Active acne can be frustrating, painful and persistent, especially when it continues into adulthood or keeps returning despite good skincare. Effective treatment matters not only for comfort and confidence but also because uncontrolled acne can leave lasting scars and pigmentation.

In Korea, patients often hear about Agnes RF, a device that delivers radiofrequency energy through insulated microneedles directly into sebaceous glands. At the same time, standard medical treatment with prescription creams and oral medications remains the foundation of acne care. This article compares Agnes RF with conventional medical treatment and explains when each may be appropriate.

How acne develops

Acne involves four main processes: excess sebum production, blockage of hair follicles by dead skin cells, the activity of acne-associated bacteria, and inflammation. Hormones, genetics, stress, certain medications and some cosmetics can make acne worse. Effective treatment usually targets more than one of these processes. Acne also ranges from mild blackheads and whiteheads to deep, painful nodules and cysts that are more likely to scar.

Medical treatment for acne

Medical treatment is guided by acne severity and type. Dermatologists typically build a plan using one or more of the following:

• Topical retinoids such as adapalene or tretinoin help unblock pores and reduce new lesions.
• Benzoyl peroxide reduces acne bacteria and helps prevent antibiotic resistance.
• Topical or oral antibiotics are used for inflammatory acne, usually for limited periods.
• Hormonal treatments such as certain contraceptive pills or spironolactone may help some women with hormone-related acne, where appropriate.
• Isotretinoin is an oral medication used for severe, scarring or treatment-resistant acne. It is highly effective but requires medical supervision because of potential side effects and the need to avoid pregnancy during treatment.

In-clinic procedures such as extraction, comedone removal, chemical peels, and steroid injections for large painful cysts are also commonly used alongside medication.

How Agnes RF works

Agnes is a radiofrequency device that uses very fine microneedles insulated along most of their length, with only the tip exposed. The needle is inserted into an individual pore, and RF energy is delivered at the depth of the sebaceous gland. The aim is to damage overactive glands and reduce oil production and recurrent breakouts in the treated pores. Because each lesion or pore is treated individually, the procedure can be time-consuming but very targeted.

• Best for: recurrent acne in specific areas, persistent inflamed lesions and people who cannot use or prefer to avoid oral medications.
• Sessions: often one to three sessions spaced several weeks apart, depending on severity.
• Downtime: redness, swelling and small marks for several days; some lesions may appear to flare temporarily.
• Comfort: local anaesthesia or numbing cream is usually used.

Agnes is also used for other purposes such as under-eye fat and sebaceous hyperplasia. For acne, its role is generally as a complement to, rather than a full replacement for, medical care.

Agnes RF vs medical treatment: comparison

• Mechanism: Agnes physically targets sebaceous glands; medical treatment addresses multiple acne pathways at once.
• Evidence base: medications such as retinoids and isotretinoin have extensive long-term research; device-based gland treatment has a smaller body of evidence.
• Speed: Agnes can reduce recurrence in treated areas after a few sessions; medications often take weeks to months to work.
• Coverage: medication treats the whole face and body; Agnes treats selected pores or areas.
• Side effects: Agnes may cause temporary redness, swelling and pigmentation; medications may cause dryness, irritation or systemic side effects depending on the drug.
• Ongoing care: medical treatment often needs maintenance therapy; Agnes may reduce the need for it in some cases.

Which should you choose?

• Mild to moderate acne: topical treatments and good skincare are usually the first step.
• Moderate to severe inflammatory acne: a dermatologist-led medical plan, possibly including oral medication, is generally recommended.
• Recurring breakouts in the same areas despite medication: Agnes RF may be considered as an additional option.
• People unable to take isotretinoin: Agnes may offer a device-based alternative for selected cases, after discussion with a dermatologist.
• Severe nodular or cystic acne: medical treatment, particularly isotretinoin where suitable, is often the most effective approach.

Combination is common. A dermatologist may control inflammation with medication first and then use Agnes for persistent areas, or use Agnes while gradually reducing medication.

Risks and considerations

Agnes RF can cause temporary redness, swelling, crusting, post-inflammatory hyperpigmentation and, rarely, small depressions or scarring if settings are too aggressive. Medical treatments carry their own risks, ranging from skin irritation to more significant effects with some oral medications, which is why supervision is important. Pregnancy, breastfeeding and other medical conditions affect what is safe, so always share your medical history and current medications.

Treating acne during a visit to Korea

A dermatology consultation in Korea can be a useful opportunity to review your acne, especially if previous treatments have not worked. Bring a list of past medications and any side effects. If you start a prescription medication, ask how to continue or monitor it safely at home, as some medications require follow-up blood tests or regular review. Agnes and other procedures may cause visible redness, so plan them earlier in your trip. Use gentle skincare and sunscreen throughout.

Conclusion

Agnes RF and medical treatment approach active acne from different angles. Medical treatment remains the foundation, addressing oil, blocked pores, bacteria and inflammation across the whole skin, while Agnes RF offers a targeted way to reduce overactive oil glands in persistent areas. For many people, the most effective plan combines both under the guidance of a dermatologist.
