K-beauty terms describe goals; treatment names describe procedures.
A term such as glass skin can mean hydration, smoother texture, more even tone or improved overall skin quality. V-line can involve jaw muscle, chin projection, facial volume or skin laxity. Aegyo-sal is different from a tear trough. The useful consultation step is to explain the look you want, then let the physician determine which confirmed Newline treatment — if any — matches the concern.
Six terms to know
K-Beauty goals translated carefully.
02
V-line (V라인)
A visual goal describing a slimmer or more defined lower face. The cause of lower-face width or heaviness should be assessed before choosing treatment.
03
Aegyo-sal (애교살)
The subtle natural-looking fullness immediately below the lower eyelid. It is an aesthetic feature, not the same as an under-eye hollow.
04
Tear trough
The groove or hollow between the lower eyelid and upper cheek. It is different from aegyo-sal because it refers to indentation rather than added fullness.
05
Jaw Botox
Common shorthand for botulinum toxin treatment of the masseter muscle in selected patients. It is not the same as surgical jaw-bone reduction.
06
Skin booster
A broad clinic term for injectable treatments aimed at skin quality rather than facial contour volume. Product choice and amount should be confirmed individually.
Treatment vocabulary
Confirmed Newline clinical terms.
Ultherapy Prime / Shurink Universe
Ultrasound-based lifting categories on Newline's confirmed menu. Exact shot count and area should be confirmed.
Thermage FLX / XERF

Confirmed injectable skin-quality treatment categories. Exact product, amount and indication should be discussed during consultation.
Fraxel / Laser Toning / CO2 / Trinity
Confirmed laser and resurfacing categories for selected texture, pigmentation, pore and scar-related concerns.
Skin concern vocabulary
Useful terms to describe what bothers you.
Melasma (기미)
A pigmentation concern often discussed as patchy facial discoloration. Treatment should follow individual diagnosis and assessment rather than a fixed laser formula.
PIH · Post-inflammatory hyperpigmentation
Darkening that can remain after inflammation such as acne or irritation. The cause and skin type matter when planning treatment.
Acne scars (여드름 흉터)
Acne scarring can include different surface patterns and depths. Newline's confirmed categories relevant to scar or texture concerns include Fraxel, Potenza and MTS.
Pore concerns (모공)
Patients often use “pores” to describe visible openings or uneven texture. Treatment planning should distinguish pores from scars, oiliness and general texture.

Common term confusion
Similar words can mean different things.
Glass skin ≠ whitening
Glass skin generally describes luminosity and skin quality, not a specific lighter skin color.
V-line ≠ jaw surgery
V-line is an aesthetic goal. Non-surgical contour treatments and jaw-bone surgery are completely different categories.
Aegyo-sal ≠ tear trough
Aegyo-sal refers to lower-eyelid fullness; tear trough refers to a hollow or groove. Newline lists separate filler options for both.
Skin booster ≠ filler
Skin boosters are generally discussed for skin quality, while dermal fillers are usually used for volume or contour. Exact products vary.

Frequently asked
FAQ · K-Beauty terms
questions.
Why are there so many K-beauty terms?
Many Korean beauty terms describe visual goals rather than standardized medical treatments. Terms such as glass skin, V-line and aegyo-sal can help explain the look a patient wants, but the actual treatment plan should be based on anatomy, skin condition and physician assessment.
Are terms like 'glass skin' medical diagnoses?
No. Glass skin and similar expressions are beauty and aesthetic terms. They can be useful starting points in consultation, but they are not medical diagnoses or fixed treatment protocols.
Can I simply ask Newline for 'glass skin'?
Yes. You can use the term to describe your goal, but Newline should then clarify whether your main concern is hydration, texture, pores, pigmentation, scars or another issue before discussing treatment options.
What does V-line usually mean?
V-line generally describes a slimmer lower-face or more defined jaw-and-chin contour. The appropriate approach can differ depending on muscle size, facial volume, skin laxity and chin projection.
What does aegyo-sal mean?
Aegyo-sal refers to the small natural-looking fullness just below the lower eyelid. It is different from a tear trough, which refers to a hollow or groove under the eye.
What is the difference between aegyo-sal filler and tear-trough filler?
They target different aesthetic concerns. Aegyo-sal filler aims to create or enhance a subtle lower-eyelid curve, while tear-trough filler addresses a hollow or indentation. Newline's current filler menu lists both under-eye aegyo and tear-trough filler options.
What does jaw Botox mean at Newline?
Jaw Botox generally refers to botulinum toxin treatment of the masseter muscle for selected patients. Newline's confirmed menu includes square-jaw Botox. Dose and suitability should be determined during consultation.
What does 'skin booster' mean?
Skin booster is a broad clinic term for injectable treatments aimed at skin quality rather than facial volume. Newline's confirmed menu includes Rejuran, Juvelook, Rituo and Hi-Ju Glow Injection. Exact product naming and suitability should be confirmed when booking.
How should I explain a K-beauty goal to Newline?
Describe the term you have researched, then explain what you specifically want to improve. Reference photos, previous treatment history and your recovery schedule can help make the consultation more precise.

Found a K-beauty term online?
Ask Newline what it
means for your concern.
Send the term, your main concern, previous treatment history and preferred date. The final treatment plan should be based on consultation, not the trend name alone.
K-beauty terms are descriptive aesthetic vocabulary and are not standardized medical diagnoses or guaranteed treatment protocols. Individual suitability and results vary. Treatment selection and final VAT-inclusive price should be confirmed with Newline Clinic after consultation.
