Treatment Guide
Botox and filler are both given by injection, but one reduces movement and the other fills volume. Based on its Ultrasound ViewTox and filler lineup, Mason Clinic, near Exit 7 of Sinnonhyeon Station in Seoul, sets out how to sort concerns about wrinkles, volume and the facial line, and how to choose.
Botox (botulinum toxin) is an injection that temporarily reduces the nerve signals to a muscle, easing excessive muscle contraction, while filler is a preparation injected beneath the skin to fill sunken areas or refine the contour. Botox acts on movement; filler acts on volume.
On the Mason Clinic menu, filler and Botox are listed separately within Skin Balance, and Botox for muscles and special areas is injected after an Ultrasound View check. Contour & Balance, which plans facial contour and volume area by area, and Tangle Fit Lip Balance, which plans lip filler and Botox together, are chosen by the same criteria.

Choosing becomes easier once you first separate whether the wrinkles appear when you make an expression, or are visible even when your face is at rest.
Even with aesthetic treatments, there are times when it is better to adjust the timing according to how you are feeling that day. If any of the following apply to you, please tell us during the consultation.
Please tell us right away if you have these symptoms after the treatment
Even with the same wrinkle, when the cause differs, so does the approach. In consultation we distinguish and check the following four.
The four often overlap, so we confirm which carries more weight before deciding the order. If the concern is a face that looks wide, we use ultrasound to determine whether fat, muscle or the salivary glands are the cause. Sometimes all three are present together.
We do not choose the product first. We check the condition of each area, then decide what to use and how much.
It is not a matter of which is better, but of what change you are trying to address. The components of Mason Clinic's Contour & Balance, Ultrasound ViewTox and Tangle Fit Lip Balance, arranged by concern, are as follows.
| Concern | Treatments considered | Main target |
|---|---|---|
| Expression wrinkles | Wrinkle & Muscle Botulinum Toxin (Xeomin · Coretox · Korean botulinum toxin products) | Expression wrinkles in the glabella, eye area, forehead and around the mouth |
| Wide-looking lower face | Ultrasound ViewTox (masseter area · salivary gland area) | The size of the muscle that makes the jaw look square, and the volume around the parotid and submandibular glands |
| Sunken volume and contour | Belotero · Juvederm (Voluma · Volbella) · Radiesse · Juvelook Volume · Jamber Threads | Volume and contour in the nasolabial folds, under-eyes, chin, cheekbones and elsewhere |
| Lips and mouth corners | Tangle Fit Lip Balance (Lip Filler · Mouth-corner Botulinum Toxin · Cobblestone-chin Botulinum Toxin) | Lip volume and shape, the direction of the mouth corners, and bumpiness on the surface of the chin muscle |
| Pores and texture | Skin Botox · Hilo Wave | Pores, texture, fine lines and elasticity |
The “main target” in the table is the direction each treatment aims for. Sometimes the two are used together, so we sort this out area by area in consultation.
When Botox is considered first
When filler is considered first
For the lips, how the balance between filler and Botox is divided depends on the condition of the lips and the surrounding muscles, so we plan them together as Tangle Fit Lip Balance. If the reason your face looks wide is fat rather than muscle or the salivary glands, we also consider Slinique™ V, a lipolysis injection, and if sagging is present as well, please see our Lifting guide too.
When we do not recommend it, or postpone it
If the change you want goes beyond what an injection can do, we tell you first, in consultation, what is realistically possible.
When results appear and how long they last depend on the treatment, the area, the product and your individual condition. The reference points given in Mason Clinic's treatment guides are as follows.
| Treatment | Guidance |
|---|---|
| Ultrasound ViewTox | Results appear within 3–7 days of treatment and last about 3–6 months. This can vary with muscle condition and lifestyle |
| Tangle Fit Lip Balance | Results last about 6–12 months on average, with individual variation. The timing of a touch-up is decided in consultation based on your condition |
| Contour & Balance | Varies with the area, the product and your individual condition; we explain the expected course in consultation |
Costs can be checked in the Non-covered Services Guide. Treatment prices vary by area, materials, and patient condition.
This article was written and reviewed by Kim Hyun-joo, Director of Mason Clinic. Decisions about treatment are made after your condition has been checked at the consultation. For Botox in muscles and special areas, the injection site is located while checking the muscle layer, salivary glands and blood vessels with ultrasound.
