Each profile uses the same decision fields so you can compare like with like. Session counts and recovery are planning ranges, not promises; the clinic must replace them with a device- and patient-specific plan.
1. Aqua Peel: A Low-Disruption Surface Treatment
Technology: Aqua Peel is a clinic service category related to hydradermabrasion. A handpiece typically combines fluid delivery, superficial exfoliation and suction, but acids, serums, passes and devices differ by clinic.
Best for: A temporary refreshed feel, superficial oil and comedonal congestion, and travelers who want minimal visible interruption.
Not for: Deep acne scars, substantial pigment disorders or laxity. Postpone when there are open lesions, infection, severe irritation or an active rosacea or dermatitis flare unless a clinician says otherwise.
Sessions: One session can be used as a short-term facial; repeat timing is preference- and skin-dependent rather than a fixed medical course.
Downtime and pain: Usually minimal pain and little visible downtime, although transient redness, tightness or irritation can occur.
Evidence: A small hydradermabrasion study reported changes in skin antioxidant levels and histologic markers, but it does not validate every Aqua Peel machine, solution or marketing claim. Evidence is more limited than for many device-based medical procedures.
Price: An active Chang Dermatology listing shows Aqua Peel at KRW 150,000. Bioface lists KRW 421,000 for five sessions and KRW 711,000 for ten; confirm what each session includes.

2. Laser Toning: A Pigment Treatment, Not General Whitening
Technology: “Laser toning” commonly means repeated low-fluence treatment with a 1,064 nm Q-switched Nd:YAG laser, although Korean listings may combine Revlite, Picoway, Genesis or other systems. Ask for the exact device, wavelength and diagnosis.
Best for: Selected pigment concerns after a clinician distinguishes melasma, lentigines and post-inflammatory hyperpigmentation. It is not a generic method to change a person's natural skin color.
Not for: Undiagnosed changing lesions, active infection or a plan built around unlimited frequent sessions. People with prior post-inflammatory hyperpigmentation or hypopigmentation need conservative settings and follow-up.
Sessions: A series is common. Active listings offer one, five and ten sessions, which reflects packaging rather than a universal dose.
Downtime and pain: Usually minimal to mild discomfort, with warmth or redness for hours and sometimes one to two days.
Evidence: Studies show low-fluence 1,064 nm treatment can improve melasma in some Asian patients, but recurrence and variable response are common. Published reports also describe mottled hypopigmentation after frequent low-fluence treatment.
Price: The Clim lists whitening toning at KRW 90,000 for one, KRW 420,000 for five and KRW 810,000 for ten sessions. Chang lists dual laser toning at KRW 250,000 and triple toning at KRW 300,000.

3. Rejuran: A Named Polynucleotide Injectable
Technology: Rejuran is a branded family of injectable polynucleotide products derived from salmon DNA fragments. Rejuran Healer, Rejuran i and Rejuran HB Plus differ by intended area or formulation; “salmon injection” and PDRN should not be assumed to be the same product.
Best for: Patients discussing gradual skin-quality improvement such as texture and fine lines, with realistic expectations that it is neither a filler nor a lifting procedure.
Not for: Anyone seeking immediate volume replacement, major scar correction or a surgical-level lift. Disclose fish allergy, pregnancy or breastfeeding, active infection, immune conditions and prior injection reactions.
Sessions: Korean clinics often recommend an initial series, but the number and interval should follow the exact product, dose, area and response rather than a universal schedule.
Downtime and pain: Multiple injections can be uncomfortable despite numbing. Temporary papules, swelling, redness, bruising and tenderness commonly affect the first one to three days.
Evidence: Small randomized and controlled studies of polynucleotide products report skin-quality changes, but methods, products and endpoints vary. The evidence should not be stretched into guaranteed collagen growth, scar removal or a fixed duration for every Rejuran formula.
Price: Active 2 cc examples include KRW 170,000 at Cheongdam Oracle and KRW 345,000 at The Clim. Rejuran HB Plus 1 cc is KRW 285,000 at The Clim; verify dose, formula and injector.

4. Other Skin Boosters: A Category That Must Be Unpacked
Technology: “Skin booster” can refer to non-cross-linked hyaluronic acid complexes, PN/PDRN products, PDLLA- or CaHA-based biostimulatory injectables, PRP or products marketed as exosomes. These ingredients have different mechanisms, injection planes and risk profiles.
Best for: A specific hydration, skin-quality or biostimulatory goal that matches a named product and a documented indication.
Not for: Anyone offered an unnamed “cocktail,” an unlabeled syringe or claims that one booster can lift, erase scars and treat pigment at the same time. Extra caution is warranted for exosome products because regulatory status and clinical evidence vary by country and product.
Sessions: One to several sessions may be proposed. Ask whether the protocol comes from product labeling, published evidence or the clinic's own practice.
Downtime and pain: Expect injection discomfort and possible marks, swelling or bruising for one to three days. Nodules, infection, allergic reaction and vascular complications are uncommon but important injection risks.
Evidence: Randomized studies support some named HA or biostimulatory injectables for selected endpoints, but results from one ingredient cannot validate another. The FDA states there are no FDA-approved exosome products and advises special caution, including for treatment obtained abroad.
Price: Active examples include Juvelook volume 2 cc at KRW 196,000, NCTF 3 cc at KRW 400,000 and Radiesse face 1 vial at KRW 450,000. These prices represent different products and should not be compared as equal doses.

5. Potenza and RF Microneedling: Needles Plus Controlled Heat
Technology: RF microneedling uses arrays of fine electrodes to enter the skin and deliver radiofrequency energy at selected depths. Potenza is one device brand; Potenza Diamond is a non-needle handpiece option in the same platform and should not be described as identical to needling RF.
Best for: Selected atrophic acne scars, uneven texture, pores and some skin-quality goals after active acne and scar type are assessed.
Not for: Home use, active infection, open lesions or a clinician who will not identify the device and settings. Disclose keloid tendency, poor wound healing, implanted electronic or metal devices, anticoagulants and prior energy-device complications.
Sessions: Three or more staged sessions are common for scars and texture; deeper or aggressive settings are not automatically more effective.
Downtime and pain: Numbing is commonly used. Redness, swelling, pinpoint bleeding or crusting may last about two to five days, with longer recovery after more intensive settings.
Evidence: Randomized and split-face studies support improvement in selected acne scars, but device settings and study populations vary. In October 2025, the FDA warned of reported burns, scarring, fat loss, disfigurement and nerve damage with certain uses and emphasized trained licensed providers.
Price: The Clim lists Potenza acne/pores and scars at KRW 255,000 for one session and KRW 720,000 for three. Chang lists Potenza Diamond at KRW 600,000 for 500 shots and KRW 1,000,000 for 1,000 shots.
→ See the Potenza RF microneedling guide and active Potenza options.
6. Fractional Laser: Match the Wavelength to the Target
Technology: Fractional lasers create microscopic treatment zones while leaving intervening tissue untreated. Non-ablative erbium-glass, fractional CO2, fractional Er:YAG and fractional picosecond systems differ substantially. “Fraxel” is a brand family, so ask for the model and wavelength.
Best for: Texture and selected atrophic acne scars. Some wavelengths and settings may also address pigment or photoaging, but one setting does not treat every concern equally.
Not for: A one-day promise to erase established scars. Active infection, uncontrolled acne, recent tanning, poor healing, photosensitizing drugs, herpes history and a strong post-inflammatory hyperpigmentation history require individualized planning.
Sessions: One to three or more sessions are common; scar remodeling should be assessed over months, not immediately after swelling subsides.
Downtime and pain: Numbing is common. Many non-ablative plans cause redness, swelling and a rough or bronzed appearance for about three to seven days. Ablative fractional treatment can require longer healing and stricter wound care.
Evidence: Randomized split-face trials support fractional laser improvement for atrophic acne scars, with tradeoffs in pain, downtime and post-inflammatory hyperpigmentation between devices. Results depend on scar type, wavelength, density and skin tone.
Price: SH Clinic lists Fraxel at KRW 440,000 for one session and KRW 1,200,000 for three. Chang lists Picoway Fractional Laser at KRW 600,000; these are different technologies and should not be treated as equivalent.
7. HIFU Versus Monopolar RF: Two Routes to Mild Tightening
Technology: HIFU or microfocused ultrasound creates focal thermal coagulation at selected depths; Shurink and Ultherapy are device families. Monopolar RF, including Thermage FLX, heats a broader volume of tissue using radiofrequency. Neither category is a laser.
Best for: Mild laxity and gradual tightening where the main issue is not severe tissue descent or major volume loss. Ultrasound may be selected for focal deeper planes; monopolar RF may be selected for broader dermal heating.
Not for: Patients expecting a surgical facelift or facial-fat restoration. FDA focused-ultrasound guidance identifies open wounds or lesions, severe or cystic acne, active implantables and metallic implants in the treatment area as important contraindication considerations.
Sessions: Often one session followed by reassessment over several months. Repeat timing is device-, dose- and patient-specific.
Downtime and pain: Pain varies by area, energy and device. Temporary redness, swelling, tenderness, tingling, welts or numbness can occur; visible recovery is often hours to several days.
Evidence: Prospective studies and systematic reviews report modest tightening from microfocused ultrasound and monopolar RF in selected patients. Outcomes are not surgical, and operator technique, anatomy and energy delivery affect both benefit and risk.
Price: Shurink Universe Ultra F 300 shots is KRW 212,000; Ultherapy Prime 300 shots is KRW 1,485,000. Thermage FLX is KRW 1,515,000 for 300 shots at Bioface and KRW 2,596,000 for 600 shots. Compare like-for-like shot counts and treatment areas.
