What is the actual difference between filler and a skin booster?
The materials differ before the technique does. A filler is cross-linked hyaluronic acid, bonded so it holds a shape under tissue pressure, and it is placed as a deposit at one structural depth. A booster is PDRN, PDLLA-HA, PLLA, CaHA or uncross-linked HA, dispersed through the dermis in droplets that are meant to spread. One is asked to occupy space; the other is asked to provoke a response.
Which one should I get for tired, dull skin?
A booster. Dullness, dehydration and fine crepiness sit in the surface of the skin, and a gel placed under it changes nothing you can see. Rejuran works through PDRN, Juvelook pairs PDLLA with HA, and both are built over a short course of sessions instead of one appointment.
Which one should I get to reshape my chin or nose?
Filler. Building projection on a chin, straightening a nose bridge or restoring a cheek is structural work that needs a firmer HA gel placed at a specific depth. A booster cannot create that kind of shape. See our dedicated chin filler page for detail.
Can I have filler and a skin booster at the same time?
Yes, and it is common — filler builds the structure while a booster refines the skin over it. At Dear Clinic we sequence them correctly so nothing competes, and both are planned from one 3D diagnosis so your total volume and cost are agreed in advance.
Is filler or a skin booster worth it for me?
Only the diagnosis answers that, because the two spend money on completely different results. Filler buys a change of shape you can photograph the same afternoon. A booster buys a change in the surface that arrives at review, and it is poor value bought impatiently. The scan tells you which deficit you actually have, and it occasionally reports neither.
How much do they cost in Korea?
HA filler starts at ₩130,000 (≈ $95) per 1 cc with The Chaeum, and the entry booster, Juvelook Volume, is ₩100,000 per 1 cc. Read the unit before you compare rows: Rejuran Healer is sold as a 2 cc pack at ₩300,000 (≈ $215) and Sculptra by the vial at ₩1,200,000 (≈ $855). Specialty zones such as the earlobe carry a higher rate for the same gel.
Which lasts longer?
Filler holds longer from a single appointment, because it stays in place as a depot until the body breaks the hyaluronic acid down. A booster leaves no depot at all, so what persists is the collagen response it provoked, and that is topped up while it is still working. We do not publish month figures for either: they move with the product, the volume, the area and your own metabolism, and your director gives you a range for your own plan after examining the skin.
Do they hurt, and is there downtime?
Both use fine needles under topical numbing, and most HA fillers carry lidocaine in the gel itself. The trade is in what you see afterwards: filler goes deeper and bruises more readily, while a booster leaves a scatter of small beads across the treated field that flatten within a day or two. Neither normally costs you an evening.
Are they reversible?
HA filler can be dissolved with an enzyme if you ever want it removed or adjusted. Skin boosters are not "reversed," but their effect simply fades over time as the material is naturally broken down, so there is nothing permanent to undo.
Can I get treated on the same day as my consultation?
Usually. The EVE 3D reading and the director's consultation happen in the same visit, and if suitability is confirmed the injection follows immediately. There is one caveat worth knowing before you plan the trip: a booster course is built over several sessions, so a single visit starts it rather than completes it. Filler finishes in one. We are open 365 days a year, holidays included.
Do prices differ for international visitors, and how do I book?
No. One published list covers residents and visitors alike; KRW is what you pay and USD is shown for reference. Send the form below with your travel dates and we reply in English within one business day, holding the slot without a deposit. If you are considering a booster course, say how many days you have in Seoul, because that changes which of the two we recommend starting with.
If I can only do one on this trip, which should come first?
Filler, in almost every case where both are indicated. It resolves in one visit, it is the half of the plan that can be dissolved if you change your mind, and it sets the structure the booster is later asked to refine. A booster started on a short trip gives you the first session of a course and no visible result to take home, which is a poor souvenir. Your director will say plainly if your own scan reverses that order.
