The official site identifies Dr. Wonjin Jo as the CEO and representative director of CHA.I Clinic.

Facial Lifting and Anti-Aging Treatments

Facial lifting is one of CHA.I Clinic's major treatment categories. Rather than relying on a single device for every patient, the clinic states that it evaluates the strengths of different technologies and selects treatment according to the individual's skin condition.

Ultherapy Prime

Ultherapy Prime uses high-intensity focused ultrasound to create thermal coagulation points at targeted skin depths. CHA.I Clinic describes it as a non-surgical lifting treatment designed to support collagen regeneration and improve sagging skin and wrinkles.

The clinic emphasizes:

• 1:1 customized treatment
• Genuine Ultherapy tips
• Full-shot treatment policy
• FDA-cleared lifting technology
• Treatment adjusted according to skin condition

The clinic's stated treatment approach is intended to produce lifting while maintaining a natural appearance and allowing patients to return to everyday activities relatively quickly.

Thermage FLX

Thermage FLX is an RF-based treatment designed to improve skin firmness and elasticity through collagen-related changes.

CHA.I Clinic emphasizes that the same device can produce different outcomes depending on treatment technique and individual skin characteristics. Its Thermage program therefore focuses on customized treatment rather than using identical settings for every patient.

The clinic highlights:

• Personalized treatment according to skin type
• RF-based collagen regeneration
• Non-surgical skin tightening
• Genuine treatment tips
• Full-shot treatment policy

Thermage FLX may be considered by patients primarily concerned with skin laxity, reduced firmness, fine lines, and overall facial elasticity.

XERF

XERF is another lifting technology featured prominently by CHA.I Clinic. The clinic currently highlights XERF among its popular lifting treatments and publishes dedicated educational content about the technology.

Depending on the patient's skin condition, XERF may be incorporated into a customized lifting plan rather than used as a universal treatment for every face.

Thread Lifting

CHA.I Clinic also provides thread lifting for patients looking for more defined facial contours and improvement in skin laxity.

Its thread-lifting information describes treatments designed to support:

• Facial contour improvement
• Sagging skin improvement
• Wrinkle and elasticity improvement
• Collagen production
• Skin regeneration

The clinic also lists a Super V-Line Body thread treatment using PDO threads for body-line improvement and skin tightening.

Thread lifting is a procedure that requires individual assessment because thread type, insertion technique, treatment area, and the degree of laxity can influence the treatment plan.

Skin Boosters, Botox, Fillers and Volume Treatments

CHA.I Clinic offers several injectable treatments for patients seeking improvements in skin quality, facial lines, elasticity, or volume.

Rejuran and Skin Boosters

Rejuran is among the treatments highlighted by CHA.I Clinic, including on its current “Best Choice” section. The clinic also publishes educational information about maximizing Rejuran results.

Skin booster treatments may be considered for concerns such as:

• Reduced skin hydration
• Uneven texture
• Fine lines
• Loss of elasticity
• Dull-looking skin
• Overall skin-quality improvement

The appropriate product and injection technique should be determined according to the patient's skin condition.

Botox

CHA.I Clinic provides Botox for facial wrinkles and selected areas affected by overdeveloped muscles.

Its official Botox information mentions treatment for concerns such as:

• Forehead wrinkles
• Glabellar lines
• Nose-bridge wrinkles
• Jaw muscle enlargement
• Facial contour concerns

The clinic emphasizes customized treatment intended to preserve natural facial expression and individual facial characteristics.

Dermal Fillers

Dermal fillers are available for areas where insufficient volume contributes to hollowing, wrinkles, or facial imbalance.

CHA.I Clinic describes filler as a minimally invasive injection treatment that can restore volume in hollow areas and improve the appearance of wrinkles and facial contours.

Depending on the consultation, filler may be considered for areas such as:

• Nasolabial folds
• Forehead
• Lips
• Chin
• Other areas with volume deficiency

Because filler placement can significantly influence facial proportions, individualized assessment is important when planning treatment.

Sculptra

Sculptra differs from conventional hyaluronic-acid filler because it uses PLLA as a collagen-stimulating material. Rather than simply creating immediate volume, Sculptra is designed to gradually encourage collagen production over time.

CHA.I Clinic's Sculptra program includes:

1. Personalized consultation
2. Topical or local anesthesia
3. Sculptra treatment using a blunt cannula
4. Aftercare instructions

The clinic emphasizes gradual, natural-looking volume and skin-quality improvement.

Pigmentation, Brightening and Skin Tone Treatments

CHA.I Clinic provides several laser options for pigmentation, melasma, blemishes, uneven skin tone, redness, and related skin concerns. The clinic's approach is to determine the characteristics of the pigmentation before choosing an appropriate laser or combination treatment.

Pico Laser

CHA.I Clinic uses a German-imported Pico Laser for pigmentation concerns and tattoo removal.

The clinic describes picosecond laser technology as using extremely short pulses to target pigmentation while reducing the amount of heat delivered to surrounding tissue. Its listed applications include:

• Deep or difficult pigmentation
• Blemishes
• Uneven skin tone
• Hyperpigmentation
• Semi-permanent makeup removal
• Tattoo removal

The treatment process includes consultation and diagnosis, laser treatment according to skin condition, soothing care, and aftercare instructions.

Lavieen

Lavieen uses a 1,927 nm wavelength and is presented by CHA.I Clinic as a treatment for pigmentation, skin tone, pores, elasticity, and wrinkles.

The clinic describes Lavieen as a non-ablative laser that can address several skin concerns in one treatment. It particularly highlights:

• Melasma and blemishes
• Hyperpigmentation
• Skin brightening
• Pore improvement
• Elasticity
• Fine wrinkles

The clinic also states that its pigmentation program aims to minimize recurrence and tailor treatment to individual skin conditions.

Cosjet

Cosjet combines 1,064 nm and 1,320 nm wavelengths and includes contact cooling. CHA.I Clinic presents it as a versatile option for pigmentation, acne, facial flushing, and certain skin-tightening concerns.

The clinic's listed process is:

1. Consultation and skin diagnosis
2. Cleansing and numbing
3. Customized Cosjet treatment
4. Soothing care
5. Aftercare guidance

The clinic specifically highlights its cooling system as part of its approach to reducing treatment-related skin discomfort.

Acne, Pores and Acne Scar Treatment

CHA.I Clinic also provides treatment programs for active acne, enlarged pores, acne marks, depressed scars, and uneven skin texture.

The clinic emphasizes that scar type differs between patients and that treatment should therefore be matched to the scar's characteristics and surrounding tissue.

Acne Care

The clinic's aesthetic acne program includes cleansing, deep cleansing, extraction, ultrasound, modeling mask, and finishing care. The clinic describes extraction as a fundamental step for clearing blocked pores and improving sebum drainage.

Acne Scar and Pore Treatments

For depressed scars and pores, CHA.I Clinic lists several technologies, including:

• Pico Fractional
• Clarity Pro
• Mosaic Echo II
• Action II

Pico Fractional is described as stimulating collagen and elastin in the dermis while addressing depressed scars, pores, wrinkles, and skin elasticity. Mosaic Echo II uses fractional CO2 technology for various scars, uneven skin tone, and deeper wrinkles.

Treatment should be selected according to the scar pattern, depth, skin condition, and degree of tissue adhesion rather than simply choosing the strongest laser.

Customized Aesthetic and Skin Care Programs

In addition to medical laser and injectable procedures, CHA.I Clinic provides a variety of aesthetic programs for hydration, cleansing, exfoliation, brightening, acne care, and skin-barrier support.

LHA LALA Premium

LHA LALA Premium is a 50-minute treatment using LHA and alkaline-based peeling steps. The clinic describes it as a peeling treatment designed to exfoliate while supporting the skin barrier and regeneration.

The listed process includes:

• Cleansing
• LHA LALA Basic
• LHA LALA Ultra
• Scalp therapy
• LLLT therapy
• Modeling mask
• Finishing

LDM Care

LDM Care is a 50-minute hydration-focused program that includes cleansing, deep cleansing, extraction, masking, LDM, and finishing care.

CHA.I Clinic presents it as a low-irritation treatment intended to support hydration, skin-barrier regeneration, elasticity, and radiance.

Aqua Peel

Aqua Peel is designed to cleanse pores and remove impurities, sebum, whiteheads, and blackheads using water-based peeling steps.

The clinic's listed sequence includes:

• Cleansing
• Deep cleansing
• AHA
• BHA
• HYD
• Modeling mask

Brightening and Whitening Care

CHA.I Clinic also offers brightening programs using ingredients such as vitamin C and iontophoresis. Its Brightening Care program is designed around cleansing, deep cleansing, iontophoresis, extraction, soothing and light-based care, a vitamin mask, and a modeling mask.

Other aesthetic programs listed by the clinic include PHA Peeling, TCA Peeling, New Aladdin Peel, Epicuren Care, Clarity Care, and Astrodome Oxygen Treatment.

Facial Contouring and Body Aesthetic Treatments

CHA.I Clinic also offers non-surgical contouring programs for patients who want to refine facial or body lines.

Facial Contouring Injection

CHA.I Clinic's contouring injection is designed to target unwanted facial fat and improve the appearance of the facial line without surgery or anesthesia.

The clinic describes the treatment as potentially helping with:

• Unwanted facial fat
• Uneven facial contours
• Fuller-looking facial areas
• Definition of the overall face line

Because facial fullness can have different causes, consultation is important before determining whether a fat-dissolving injection is appropriate.

Body Meridian and Décolleté Care

CHA.I Clinic also provides customized body meridian and décolleté care.

Programs include:

• Lower-body therapy
• Full-body care
• Neck and shoulder care
• Décolleté care

The clinic describes these programs as customized according to the individual's body condition, with treatments designed around areas affected by tension, circulation-related discomfort, stress, or loss of balance.

Laser Hair Removal

CHA.I Clinic offers Clarity laser hair removal using a non-contact system with built-in cooling.

The clinic describes the treatment as targeting hair follicles with a 755 nm Alexandrite wavelength and using cooling to reduce skin irritation. It can be used for different hair thicknesses and is positioned as a hygienic treatment because the device does not require direct contact with the skin.

For international visitors, the appropriate number and spacing of sessions should be discussed before planning treatment around a short Seoul trip.
