4.1 The Order of Designing Margin (Current Post)
Your lower face looks wide, and you're not sure if it's muscle, sagging, or fat. So which one do you treat first? If it's a mix, the usual order is: lift the sagging foundation with Ultherapy first, reduce muscle volume with Botox next, and tidy up localized fat with fat-dissolving injections last. Ultherapy and Botox work on different layers, so they can often be done on the same day. Fat-dissolving injections are usually booked on a separate day.
There's one condition. This order only matters when two or three causes overlap. If your self-check points to just one cause, one treatment is often enough.
Facial margin rarely comes from a single factor. For most people, it's a combination of two or three. That's why what changes your impression is often not "which treatment you get," but "the order you address them in."
Why doesn't my face look different after treating just one thing?
When several causes overlap, fixing one may improve that spot. But your overall impression can still feel unfinished.
Say you have large chewing muscles and some sagging. If you only shrink the muscle with Botox, your jawline gets slimmer. But your sagging cheeks may stand out even more. Flip it around. If you only lift the sagging and leave developed muscles alone, the muscle volume stays in the lifted position. The result can be cut in half.
So before choosing any single procedure, I look at the makeup of the margin first. How much of it is muscle? How much is sagging? How much is fat?

Ultherapy, Botox, or fat-dissolving first? Start with sagging
When the causes are mixed, there is a generally recommended sequence.
Step | Target | Treatment |
|---|---|---|
Step 1 | Sagging Foundation (SMAS* Laxity) | Ultherapy Lifting |
Step 2 | Excess Muscle Volume | Masseter, Temporalis, & Salivary Gland Botox |
Step 3 | Localized Fat (Targeting with Deoxycholic Acid*) | Fat Dissolving Injections |
* SMAS: The fascial layer under the skin that wraps around the muscles. When it loosens, tissue slides down and the face looks saggy. It's the foundation of framing your face.
* Deoxycholic Acid (DCA): An ingredient that breaks down fat. In Korea, it is the single ingredient approved by the MFDS (Korean FDA) for fat reduction.
Why sagging first? Because it's the foundation. If you remove fat while the sagging stays, nothing is left to support the area. It can look even more sunken. Lift the foundation, then reduce muscle volume, then contour the leftover fat. That flow tends to give the most stable result.
It isn't a rigid rule, though. If someone has large chewing muscles plus double chin fat, we usually shrink the muscle first with Botox to set the contour, then clean up the remaining fat. If sagging is deep, we start by looking at a non-surgical facelift and layer the rest on top. The point is to sort out what is the foundation and what is the finishing touch.

Can I get Ultherapy and Botox on the same day?
Having an order doesn't mean waiting months between every step.
Ultherapy (sagging) + Botox (muscle) work on different layers of tissue, so they can be done on the same day. You lift the foundation and reduce muscle volume at once.
Fat-dissolving injections can cause swelling or bruising for a few days, so they're often scheduled on a separate day.
Every case is different. Whether to combine or split depends on your skin condition and how fast you recover. Trying to do everything at once out of eagerness is rarely the cleanest path. Adjusting step by step usually gives a more natural result.
Timing matters too. Ultherapy changes show up gradually over two to three months as collagen builds. Botox also takes a few weeks before volume visibly drops. So letting one treatment settle before adding the next lets you see what worked, and by how much.

Not sure where to start? Begin with what stands out most
It looks complex, but the rule is simple: start with the factor that stood out most in your self-check.
Clench your teeth. If hard muscle is the first thing you feel, start with Botox.
Lie down. If your face looks much slimmer, prioritize sagging.
Pinch the area. If soft fat bothers you most, address localized fat first.
After that, clean up the remaining margin in order.
Sorting out the cause first helps you skip treatments you don't need. Even for the same concern, the approach differs depending on the cause. Looking at the makeup of your own margin, rather than following whatever is trending, saves both time and money. You don't have to do it all at once.

Lost weight and your jawline sagged? Sagging may be the foundation
After weight loss, especially fast weight loss, volume around the jaw can drop and skin sagging can become more noticeable. With age, as collagen and elastin decrease, that sagging can get worse.
In that case, sagging is often the foundation in your mix. At Beautystone, Ultherapy is considered a suitable option for people bothered by sagging after weight loss, since it works on sagging skin and soft tissue and helps with collagen production. One condition matters a lot: the treatment depth is checked with ultrasound, and treatment is limited to areas that actually sag.
The starting point stays the same: figure out where your margin is coming from. Once you know, the path splits clearly. Botox for muscle, Ultherapy for sagging, fat-dissolving injections for localized fat. And if they're mixed, plan step by step, starting from the sagging foundation.
Frequently Asked Questions
Q. What if I don't follow this order? Will it not work?
It's not that there's no effect at all. But if you remove fat while leaving the sagging as is, the area can look more hollow. Lifting the foundation first makes the result more balanced and stable.
Q. Do I need all three treatments?
No. If your self-check points to one standout factor, that one treatment is often enough. We only combine them in sequence when several causes overlap.
Q. Can Ultherapy and Botox be done in one visit?
They work on different layers, so the same day is possible. Fat-dissolving injections can leave a few days of swelling or bruising, so they're usually done on another day. The final call depends on your skin condition and recovery pace.
Q. I'm worried it will cost too much.
You don't have to do everything at once. Go step by step, starting with the most prominent factor. Finding the cause and doing only what's needed is actually more cost-effective.
