Enlarged Pores & Acne Scars — Treatment Options in Seoul

Medically reviewed by Kim Yunseok, CEO / Representative Director · Last updated July 2026

Enlarged pores and acne scars are among the most common skin concerns that bring patients to clinics in Seoul. Pores can appear larger due to genetics, oil production, sun damage, or loss of surrounding collagen, while acne scarring often leaves shallow depressions or uneven texture that can take years to fade on their own. Many visitors search for an enlarged pores treatment Seoul option that also helps refine overall skin texture, since these two concerns frequently overlap. This page explains what enlarged pores and acne scars are, and outlines how the collagen-stimulating treatments available at DERNA Clinic may be considered as part of a broader skin-texture approach.

What enlarged pores and acne scars are

Pores are natural openings for hair follicles and oil glands. They can look larger when skin loses elasticity, when oil production increases, or when the surrounding tissue thins with age. Acne scars form when inflammation from breakouts damages the deeper layers of skin, sometimes leaving indented or textured areas once healed. Neither condition is dangerous, but both can affect how skin looks and feels, and many patients look for non-surgical enlarged pores treatment Seoul clinics offer as a starting point before considering more invasive options.

It is worth noting that no single treatment eliminates pores or scars completely. Skin texture concerns are usually managed gradually, with realistic goals centered on improvement rather than complete removal.

Who this approach suits

Radiofrequency and ultrasound-based collagen treatments, such as those offered at DERNA Clinic, may be suitable for patients who:

  • Have mild to moderate enlarged pores linked to skin laxity or thinning collagen
  • Notice early textural changes from prior acne, rather than deep pitted scarring
  • Prefer a non-surgical option with limited downtime
  • Are looking for a general improvement in skin firmness alongside pore appearance

These treatments work by heating deeper skin layers to encourage the body's own collagen production over time. Because they were designed primarily as lifting and tightening treatments, any improvement in pore appearance or scar texture is generally considered a secondary benefit rather than the primary goal.

Who should avoid this approach

These treatments may not be appropriate for everyone. Patients with active skin infections, open acne lesions, certain autoimmune conditions, pacemakers or other implanted electronic devices, or those who are pregnant should discuss alternatives with a physician. Individuals seeking correction of deep, pitted acne scarring may find that radiofrequency or ultrasound devices alone provide only limited change, since these scars often involve structural tissue loss that responds differently to heat-based collagen stimulation. A consultation with a DERNA Clinic doctor can help determine whether this type of treatment is a reasonable fit for your specific skin concern.

How a session goes

A typical visit begins with a consultation and skin assessment, where the treating doctor reviews your medical history, skin type, and specific concerns regarding pores or scarring. Photographs may be taken to track progress. Before treatment, the skin is cleansed and a topical numbing cream may be applied depending on the device and shot count selected. During the session itself, the device is passed over the treatment area in a grid pattern, delivering controlled energy pulses. Patients commonly describe a warming or tingling sensation, with intensity adjusted based on comfort. Sessions can range from around 30 minutes to over an hour depending on the treatment area and number of shots selected.

Downtime and recovery

One advantage of radiofrequency and ultrasound treatments is the relatively short recovery period compared to surgical options. Most patients experience mild redness or warmth in the treated area for a few hours afterward. Some may notice slight swelling that resolves within a day or two. Makeup can typically be applied the following day, though the clinic's staff can advise on specific aftercare based on your treatment. Results are not immediate; collagen remodeling takes place gradually, and visible improvement in skin firmness or texture is usually reported over the following weeks to months. Individual results vary, and some patients may require repeat sessions to notice meaningful change.

Safety

Radiofrequency and ultrasound treatments have been used in aesthetic medicine for a number of years, but they are not without risk. Reported side effects can include temporary redness, swelling, bruising, or, rarely, blistering or changes in skin sensation. There is no guarantee of a specific outcome, and results differ from person to person based on skin condition, age, and treatment settings. A thorough consultation with a physician at DERNA Clinic before treatment is important to review your medical history and set realistic expectations.

Frequently asked questions

Can Thermage FLX or Ultherapy Prime make my pores disappear completely?

No treatment can eliminate pores entirely; these devices work by stimulating collagen over time, which may improve skin firmness and the appearance of pores, but results vary and complete removal is not a realistic expectation.

How many sessions are usually needed to see a difference in pore appearance?

Many patients consider a single session to start, though some choose follow-up treatments after several months depending on how their skin responds; your doctor can advise on a suitable plan during consultation.

Are these treatments effective for deep acne scars?

Radiofrequency and ultrasound treatments may offer some improvement in skin texture, but deep or pitted scars involving significant tissue loss often respond less predictably to these devices alone, so a doctor's assessment is recommended before setting expectations.

What is the recovery time after a Thermage or Ultherapy session?

Most patients return to normal activities the same day, with mild redness or warmth that typically settles within a few hours to a couple of days.

Will I need to avoid sun exposure after treatment?

Sun protection is generally recommended after these treatments, as skin may be more sensitive during the healing and collagen-remodeling phase; your treating doctor can give specific aftercare guidance based on your skin type.
