Treatment Overview
The KTP Laser (532 nm potassium-titanyl-phosphate laser) is a visible green light laser widely used in Korean dermatology clinics for acne-related redness, active pimples, and post-acne vascular marks. It works by targeting oxyhemoglobin in superficial blood vessels, shrinking inflamed vessels that feed acne lesions and reducing redness associated with active breakouts.
Unlike ablative or resurfacing lasers, KTP is a vascular-specific laser, making it especially effective for red, inflamed acne and post-acne erythema (red marks). In Korea, it is often combined with acne extraction, blue light therapy, or toning lasers for a comprehensive acne and scar program.
Purpose & Benefits
- Redness Reduction: Shrinks superficial vessels causing acne-related redness.
- Acne Inflammation Control: Calms swollen, inflamed pimples.
- Post-Acne Mark Improvement: Fades lingering vascular scars and erythema.
- Gentle & Precise: Targets only red areas without damaging surrounding skin.
- Skin Tone Refinement: Brightens and evens out overall complexion.
Ideal Candidates
KTP Laser in Korea is recommended for:
- Patients with inflamed red pimples.
- Individuals suffering from post-acne erythema (red marks after acne clears).
- Those with sensitive skin unable to tolerate aggressive treatments.
- Patients seeking a no-downtime option for acne redness.
Possible Risks & Complications
KTP is considered very safe when performed in Korean dermatology clinics, but mild effects may include:
- Temporary Redness & Warmth: Fades within hours to a day.
- Slight Swelling: Around treated pimples, subsides quickly.
- Rare Risks: Blistering or pigmentation changes if overly aggressive settings are used (minimized with conservative Korean low-fluence protocols).
Surgical Techniques Used
- 532 nm KTP Laser: Specifically targets oxyhemoglobin in vessels.
- Spot Treatment: Directed only at inflamed lesions or red marks.
- Multi-Pass Low-Fluence Protocols: Gentle repeated passes reduce redness gradually.
- Protocol: 3–5 sessions spaced 2–4 weeks apart.
Recovery & Aftercare
Immediately: Mild redness and warmth.
1–2 Days: Acne redness decreases noticeably.
1 Week: Lingering red marks start to fade.
Aftercare Tips:
- Apply SPF 50+ sunscreen daily to prevent pigmentation.
- Avoid heat exposure (saunas, hot yoga) for 1–2 days.
- Use soothing moisturizers to calm skin.
- Do not pick or scratch treated lesions.
Results & Longevity
- After 1 Session: Calmer skin, reduced redness.
- After 2–3 Sessions: Noticeable fading of post-acne red marks.
- After 4–5 Sessions: Significant long-term improvement in acne erythema and overall tone.
Maintenance every 6–12 months may be recommended for persistent redness.
