Gold PTT Sebaceous & Acne Photothermal Therapy
Selective photothermal acne therapy using ultrasound-delivered gold nanoparticles and dermatology laser activation to target overactive sebaceous glands and chronic breakouts.
Treatment Overview & Clinical Mechanism
Gold PTT (Photothermal Therapy) is an advanced medical acne protocol within our Acne, Scar & Redness Treatment center that targets the root cause of recurring breakouts: hyperactive sebaceous glands. Unlike conventional surface topical applications, Gold PTT utilizes specialized surface-engineered gold nanoparticles delivered deep into the pilosebaceous follicles via medical ultrasound sonophoresis.
Once the gold microparticles selectively accumulate inside the pores and sebaceous glands, a specific dermatology laser wavelength is applied to induce localized photothermal heating. This controlled thermal reaction down-regulates sebum production, clears Cutibacterium acnes colonization, and calms follicular inflammation while sparing surrounding epidermal tissue. At ReYeonK Clinic, every Gold PTT session is customized through a 1:1 physician consultation with Dr. Lee Doochan, Dr. Kim Hyunsu, and Dr. Choi Hyunho.
Ideal Candidates & Target Concerns
- Patients with chronic, recurring inflammatory papules and pustular acne along the jawline, cheeks, or T-zone
- Individuals experiencing excessive facial sebum secretion and persistently congested pores
- Patients seeking a targeted non-oral alternative or adjunct to systemic acne medications
- Those with early post-acne erythema (redness) who benefit from combined vascular and sebaceous care
- Patients planning comprehensive pore and scar care alongside Potenza Microneedling RF

Step-by-Step Procedure Process
- 1:1 Physician Consultation: Detailed evaluation of acne grade, sebum distribution, and skin barrier status.
- Deep Pore Cleansing & Extraction: Gentle medical cleansing and sterile extraction of active comedones where clinically indicated.
- Ultrasound Nanoparticle Delivery: Application of medical-grade Gold PTT ampoule absorbed into sebaceous follicles via ultrasound waves.
- Selective Laser Activation: Precision laser irradiation to trigger localized photothermal action inside targeted sebaceous glands.
- Post-Procedure Soothing Care: Cooling mask and barrier-repair moisturizer application to calm transient thermal warmth.
Post-Treatment Care & Clinical Safety Notice
- Use a gentle, non-comedogenic cleanser and apply broad-spectrum sunscreen (SPF 30+) daily.
- Avoid saunas, steam rooms, strenuous exercise, and alcohol consumption for 3 to 5 days post-treatment.
- Refrain from using harsh physical scrubs, high-strength retinoids, or AHA/BHA exfoliants for 1 week.
Individual results vary depending on skin phototype, barrier sensitivity, and anatomical factors. Potential temporary side effects include localized erythema (redness), mild swelling, bruising, transient dryness or flaking, pigmentary shifts, or rare infection/vascular complications, which require proper post-treatment care and physician guidance.
Frequently Asked Questions
Q. How soon will I notice reduced oiliness and fewer breakouts?
Most patients notice a gradual reduction in excess sebum and inflammatory lesions after their second session, with progressive stabilization across a 3-to-5 session protocol.
Q. Can Gold PTT be combined with medical peels or scar lasers?
Yes. Depending on your skin condition, our physicians often alternate Gold PTT with LHALA Peel 4th-Generation Barrier Renewal or Potenza Microneedling RF. To schedule your personalized acne evaluation, please visit Contact Us.
