Skin smoothing injection: what it does for pores and texture, and who it suits

What is skin smoothing injection, and how is it different from regular anti-wrinkle injection?

Hello, I'm Dr. Won Sin Lee, a board-certified dermatologist trained at Asan Medical Center in Seoul, where I also serve as an adjunct professor of dermatology. Here I'll explain what skin smoothing injection does, what it doesn't, and how I decide whether it fits a face.

Maybe your makeup won't sit, your pores look bigger in every photo, and your skin looks rough even when it feels clean. Skin smoothing injection is one of the treatments I use for exactly that. It's also one of the most misunderstood, because people assume it will freeze their face.

Regular anti-wrinkle injection is injected deep into a muscle to relax it, which is how forehead or frown lines soften. Skin smoothing injection, sometimes called a microdroplet anti-wrinkle injection, uses diluted neuromodulator injected shallowly into the dermis instead, in many tiny points across the surface.

Because it sits in the skin rather than the muscle, skin smoothing injection doesn't stiffen your expression the way muscle-relaxing injection can. That's why it can be spread across the whole central face without the frozen look people fear.

What does skin smoothing injection do for textured skin and pores?

Each pore has a tiny muscle beside it, the arrector pili. Skin smoothing injection relaxes it, so enlarged pores look tighter. The same injection also tends to pull the surface a little tauter, so textured skin reads smoother.

• Pores: tightened and refined, especially on the front cheeks and around the nose
• Oiliness: excess shine is reduced, so makeup lasts better
• Fine lines: shallow creases on the surface are smoothed
• Flushing: it may also help redness, by suppressing small nerves around blood vessels

One honest caveat: pores can't be removed, and they shouldn't be. They're the normal outlet for sebum, which protects the skin. The goal is pores that look smaller and a surface that looks even, not skin without pores.

Because the effect is on the surface, people usually notice it as an overall impression. The central face looks smoother, photos look kinder, and foundation stops settling into pores.

Where is skin smoothing injection injected, and how does it feel?

I mainly treat the central face: the front cheeks and the area around the nose, where pores and oil are most visible. If fine lines bother you, I may add the forehead or around the eyes.

The injections are shallow and closely spaced, so you'll see small marks on the treated area for a short time. The dermatologist decides the dose for each area at the consultation. We use only US FDA-approved neuromodulator, with genuine product and quantity guaranteed, as described on our neuromodulator page.

At WELLS, a board-certified dermatologist handles the consultation, diagnosis and treatment. I'd rather spend the consultation finding out which of your concerns is most urgent than sell you a fixed menu.

Skin smoothing injection or a Rejuran skin booster: which does your skin need?

This is the question I'm asked most. The answer depends on whether your problem is on the surface or underneath.

• Rough texture, visible pores, shine: skin smoothing injection works on the surface
• Dull, dry-looking skin even though texture is fine: this usually means the skin lacks moisture inside, which is a job for a Rejuran skin booster
• Both at once: combine them

A Rejuran skin booster such as Rejuran HB+ works on regeneration, hydration and elasticity from within. It adds hyaluronic acid to the polynucleotide, so hydration improves and a dull tone can look brighter. Skin smoothing injection alone tightens the surface but doesn't solve inner dryness.

For the full picture of how Rejuran works, what it costs and who it suits, see Rejuran skin booster: what it does, who it suits, and the price.

Rejuran Tox: skin smoothing injection and Rejuran HB+ in one visit

Both skin smoothing injection and Rejuran are placed in the dermis, so they can be done in the same session. At WELLS we call that combination Rejuran Tox: Rejuran HB+ 3 cc and skin smoothing injection 3 cc, in one visit.

Rejuran rebuilds from inside, and skin smoothing injection refines the surface. Together they target fine lines, pores and texture in a single protocol, with one round of injections instead of two.

Both neuromodulators are genuine and dosed by the dermatologist, so tell us your preference. The price of skin smoothing injection on its own is confirmed at consultation, because it depends on the areas and dose.

How to get Korean glass skin: where skin smoothing injection fits

Glass skin is really three things at once: a smooth surface, good hydration and even tone. Skin smoothing injection covers only the first. That's why people who ask me how to get Korean glass skin usually need a combination, not a single injection.

Home care still matters. Cleanse properly at the end of every day, avoid oil-heavy cosmetics that can block pores, and have acne treated early instead of squeezing it. Squeezing damages the tissue around the pore and can make it larger.

If pores are already stretched from ageing or old acne, home care alone has limits. Collagen-building treatments help there, such as the fractional picosecond laser described on our pore reduction page.

When skin smoothing injection is not the right answer

Skin smoothing injection won't lift sagging skin, fill hollows or erase a deep, fixed wrinkle. If your pores look bigger mainly because the skin has lost firmness, they're stretched by laxity, and a lifting or collagen treatment will do more.

The same goes for deep expression lines. Muscle-relaxing injection in the forehead, between the brows and around the eyes works best before lines become fixed, which is why I suggest it regularly from the thirties. Once a line is etched in at rest, neither kind of anti-wrinkle injection will fully erase it.

Even a fast-acting treatment can backfire if it doesn't suit your current skin. I'd rather tell you honestly that another option fits better. If you're comparing brands or muscle-relaxing injection prices, I cover that in Korean anti-wrinkle injection in Seoul: brands, price and how a visit works.
