Pores & acne scars

In short

For pores and sunken acne scars, we combine POTENZA, Fraxel, pico fractional and subcision, which stimulate the dermis to help new collagen fill in, according to the scar type. POTENZA and pico fractional are usually done every 4 weeks over several sessions, and redness and swelling after POTENZA may last about 1–4 days.

How it works

POTENZA inserts fine needles into the skin and releases radiofrequency heat from the needle tips to stimulate the dermis directly. Fraxel and pico fractional use a laser to create tiny, closely spaced dot-shaped stimuli in the skin, so that new collagen forms as the surrounding skin recovers. For scars whose base is pulled down by fibrous tissue, such as rolling scars, subcision is sometimes used to release those connections.

The device and combination are decided by the scar shape (ice pick, boxcar, rolling) and depth, and by your oil and acne condition. If acne inflammation is severe, a treatment that addresses inflammation and oil glands, such as Agnes, is sometimes done first.

What happens on the day

  1. First, we check the cause of the pores or scars (oil, loss of firmness) and the scar shape (ice pick, boxcar, rolling).

  2. For POTENZA and Fraxel, numbing cream is applied before treatment and you usually wait about 20–30 minutes.

  3. Before starting POTENZA, we first show you what it feels like, and the first session starts at low energy and is adjusted.

  4. Right after POTENZA, PDRN or a skin booster may be applied to the skin if needed, and makeup is possible after 2–3 hours. We give you written aftercare instructions.

Safety

Who should not have it

  • We advise postponing most treatments during pregnancy or breastfeeding. If you have an implanted electronic device such as a pacemaker, you cannot have radiofrequency treatment, and if you tend to form keloids or take acne medication (isotretinoin), the type of treatment needs to be adjusted, so please be sure to tell us.
  • When acne inflammation is severe, treatment to calm the inflammation comes first, and pico fractional is sometimes postponed when the skin is very oily. If your skin is red or stinging from a recent sunburn, it is better to wait until it settles.

Side effects and cautions

  • Redness and swelling may last 1–4 days after POTENZA, small scabs and redness 3 days to 1 week after Fraxel, 3–7 days after Agnes, and bruising and swelling 1–2 weeks after subcision. Breakouts may also appear temporarily.
  • Rarely, hyperpigmentation or long-lasting redness may occur, so we adjust the energy to your skin condition. If you have blisters, severe pain or breakouts that last, do not squeeze or pick at them; contact us right away.

Aftercare and your flight home

  • After POTENZA, you can wash your face gently the same day, and for a few days use a gentle moisturizer instead of alcohol toners or vitamin ampoules. Do not force Fraxel scabs off; apply recovery cream or moisturizing cream.
  • Avoid exercise that makes you sweat a lot, saunas and alcohol until the redness settles, and apply sunscreen when you go out. The standard interval for the next visit is 4 weeks for POTENZA and pico fractional and 1 month for Fraxel.
  • Redness or scabs may last 3 days to 1 week after Fraxel or pico fractional, so we suggest leaving at least 2–3 days before your return flight. If possible, it is better to have treatment early in your trip and check your progress while you are still in Korea.

Questions about this treatment

Which devices do you use for pores and scars?
We mainly use POTENZA, a microneedle radiofrequency device, along with Fraxel and pico fractional, and plan subcision for rolling scars and Agnes for treating acne-related oil glands. We also use a CO2 laser for scar treatment, and combine devices according to the scar shape and depth.
Do pore and scar treatments hurt?
POTENZA causes a stinging, hot feeling from the needles and heat, so as with Fraxel, numbing cream is usually applied before treatment. We show you what it feels like before starting, and adjust the energy if it hurts.
Can I return to daily life right after treatment?
After POTENZA, redness and swelling last about 1–4 days, and makeup is possible after 2–3 hours. Redness after pico fractional usually lasts 3–4 days, small scabs and redness after Fraxel 3 days to 1 week, 3–7 days after Agnes, and bruising and swelling after subcision 1–2 weeks, so leave some time if you have important plans.
How many sessions do I need, and how often?
POTENZA and pico fractional are usually done every 4 weeks and Fraxel every 1 month over several sessions. Subcision is done at least 1 month apart (2 months suggested), with other regenerative treatments in between. The number of sessions is decided by the scar depth and your skin response.
