Direct answer: Yes, in most cases. The deciding factor is whether the treatment breaks the skin or creates a wound that must heal again. Hyaluronic acid filler, botulinum toxin, skin boosters, ultrasound lifting, Thermage, Onda and non-ablative pico laser do not leave an open wound and carry relatively low risk. Ablative laser, deep resurfacing and incisional procedures need assessment by a dermatologist, and often a small test area before full treatment.

How do I know whether I am keloid-prone?
- Look at old scars: the hallmark feature is a scar that rises above the skin and extends beyond the boundary of the original wound, creeping into surrounding normal skin. A hypertrophic scar stays within the original wound margins
- Look at duration: keloids do not fade on their own and often stay red, itchy or tender for more than six months and sometimes years. Ordinary scars usually flatten and pale over six to twelve months
- Look at location: the chest, shoulders, upper back, earlobes and lower abdomen are keloid-prone sites. A raised scar at any of these raises the risk noticeably
- Family history: keloid tendency runs in families. A first-degree relative with keloids increases risk and should be mentioned at consultation
- Skin tone: higher rates are seen in darker skin tones, though this is one risk factor among several and not a prediction on its own
Why is “does it create a wound” the dividing line?
- Keloids come from over-repair in the dermis: after injury, fibroblasts produce excess collagen and scar tissue grows outward. If a treatment does not disrupt the dermis or leave a wound that has to heal again, that pathway is largely absent
- Injectables leave only a needle track: filler, botulinum toxin, skin boosters and thread entry points are needle-sized and heal quickly, so most keloid-prone patients tolerate them well
- Energy devices depend on depth: ultrasound and Thermage work at depth without removing the surface, so risk stays low. Ablative laser and resurfacing remove an entire layer of epidermis, which is an entirely different risk tier
- Tension is the second variable: areas under stretch during healing are more prone to abnormal scarring, which is why the chest and shoulders are common sites. The face is under less tension, though the jawline and behind the ear still warrant care
How should procedures be tiered by risk?
- Relatively low risk: botulinum toxin, hyaluronic acid filler, skin boosters and other injectables, ultrasound lifting, Thermage, Onda body contouring and non-ablative pico laser — no open wound, needle-sized entry points that heal fast
- Moderate risk: RF microneedling, dermaroller, thread lifting (multiple entry points and a subcutaneous channel) and toning lasers that produce a visible surface response — feasible with pre-treatment assessment and preventive aftercare
- Higher risk, case by case: ablative CO2 laser, deep resurfacing, excisional mole removal and incisional procedures — these create a wound that must heal again, so keloid-prone patients usually need a test area or an alternative
- One more point: risk varies by site within the same person. A keloid on the chest does not mean the face will behave the same way, so assessment should focus on the area actually being treated
How to choose a clinic that takes scar risk seriously: three criteria
- Does intake cover scars site by site: a careful clinic does not just ask whether you are scar-prone. It asks about healed injuries on the chest, shoulders, earlobes, abdomen and face separately, plus family history, because risk differs substantially by site
- Does it explain whether the treatment leaves a wound: the physician should state clearly whether a procedure is needle-level, surface-response level or incisional, and what that means for scar risk, rather than only describing results
- Is there an early intervention plan: a proper clinic explains what can be done, and when, if thickening or persistent redness appears. Early management works far better than treatment months later
What actually happens at Rappoel
- Site-by-site scar history: intake covers how old injuries healed on the chest, shoulders, upper back, earlobes, abdomen and face, whether any scar extended beyond the wound, any prior scar treatment, and family history
- Risk tier explained: a board-trained dermatologist explains which tier the proposed treatment falls into and what the alternatives are, so you decide with full information
- Test placement for higher concern: where risk is uncertain, a small area is treated first and observed for several weeks before the full plan proceeds
- Baseline photography: photographs are taken beforehand so healing can be compared objectively at follow-up rather than from impression
- Manufacturer-certified products: treatments use certified products and threads with traceable batch numbers
- Wound care and follow-up: written aftercare is provided and healing is reviewed at one week, one month and three months, with earlier assessment arranged if thickening or persistent redness appears
Side effects and who should wait
- Ordinary responses: brief redness after injection and needle-point scabbing settle within days and are part of normal healing, distinct from abnormal scarring
- Signs worth attention: thickening at the site, firm texture, redness or itch lasting beyond a month, or scarring extending past the treated area all warrant an earlier review
- Who should postpone: anyone with a keloid at the same site still under treatment in the past six months, anyone midway through intralesional steroid injections, or anyone whose wound has not yet stabilised should finish existing care first
- Who needs referral: patients with autoimmune disease, those on immunosuppressants, or those with clearly abnormal wound healing should complete specialist assessment first
Frequently asked questions
Q1: Does keloid-prone skin rule out aesthetic treatment entirely?
No. Keloid tendency is not a contraindication. What matters is whether a procedure cuts the skin or creates a wound that has to heal again. Fillers, botulinum toxin, skin boosters, ultrasound and Thermage do not leave an open wound and are usually suitable, while ablative laser and incisional work need individual assessment.
Q2: Will filler or thread lifting give me a keloid?
The risk is low. These treatments leave only needle-sized entry points rather than a wound that has to heal again. Keloids occur most often on the chest, shoulders and earlobes where tension is high, and are far less common on the face. Mention your scar history beforehand so the physician can decide whether to adjust the approach.
Q3: How do I tell a keloid from a hypertrophic scar?
Look at the boundary and the timeline. A keloid rises and extends beyond the original wound margins and does not fade over time. A hypertrophic scar stays within the wound and usually flattens and pales over six to twelve months. If you are unsure, a physician can assess it on examination.
Q4: I had a keloid on my chest. Can I still have facial treatment?
Usually yes. Keloid formation is closely tied to tension at the site, and the chest and shoulders are high-tension areas while the face is much lower risk. Assessment focuses on whether the face, and the specific area being treated, has had abnormal scarring before, plus family history.
Q5: How does Rappoel assess patients with scar-prone skin?
Scar history is taken site by site along with family history, a dermatologist explains the risk tier of the proposed treatment and the alternatives, and where concern remains a small test area is treated and observed for several weeks before the full plan. Baseline photographs are taken and healing is reviewed at one week, one month and three months.
Q6: Will the assessment cost extra or come with pressure to book?
The purpose of assessment is to decide whether treatment is appropriate, and if risk outweighs benefit the physician recommends postponing or switching approach. You can complete the assessment and decide afterwards without committing on the day.
Q7: What if a scar does start to thicken afterwards?
Earlier intervention works better. Options include intralesional steroid injection, silicone sheeting and pressure therapy, and laser-assisted improvement, chosen according to the stage and site of the scar. Thickening, firm texture, or redness and itch beyond a month should prompt an earlier visit rather than waiting months.
Q8: Are pico or toning lasers safe for scar-prone skin?
It depends on whether the laser is ablative. Non-ablative pico leaves the surface intact and carries lower risk. Toning lasers produce a visible surface response and sit in the moderate tier, needing more careful aftercare. Ablative CO2 and deep resurfacing are higher risk and need individual assessment or a test area.
Q9: Why do some clinics never ask about scarring?
Because facial keloids are uncommon, some clinics keep intake brief. But a full scar history avoids high-risk sites and unsuitable procedure types, and the more thorough the intake, the lower the chance of needing corrective treatment later.
Q10: Where is Rappoel and how do I get there?
The clinic is at 77 Seocho-daero, Seocho-gu, Seoul, near Gangnam Station, roughly a five-minute walk from Exit 2. Hours are Monday to Friday 10:00-19:00 and Saturday 10:00-17:00, closed Sunday, with Chinese and English consultations available.
