What Is Skin Botox? Korean Microtox for Glass Skin, Explained
By Dr. Lydia Park, MD, Medical Director at Seoule K-Beauty Skin Lab. Last updated: July 2026.
Skin botox, also called microtox, is a Korean technique that injects highly diluted botulinum toxin superficially into the skin rather than deep into muscle. Instead of freezing expression, it refines pores, reduces oil and sweat, softens fine surface lines and boosts light reflection for a smooth, glass-skin finish. At Seoule K-Beauty Skin Lab in San Diego, results appear within one to two weeks and typically last two to three months.
Traditional Botox has been a household name for decades, but a newer, more delicate version has become one of the most requested treatments in Korean clinics. Skin botox is the secret many people are actually chasing when they ask for that poreless, glossy, K-beauty complexion. Here is exactly what it is, how it differs from the Botox you already know, and whether it is right for you.
What is skin botox (microtox)?
Skin botox is a technique in which a very diluted form of botulinum toxin is delivered through many tiny, superficial injections just beneath the surface of the skin. Because it sits in the upper layers rather than deep in the large muscles of expression, it works on the small structures tied to pores, oil glands and fine surface texture instead of switching off movement. The result is smoother, tighter, less oily skin that reflects light more evenly, which is the essence of the glass-skin look.
How is skin botox different from regular Botox?
The active ingredient is the same, but the technique, depth and goal are completely different. Regular Botox is injected into specific muscles to relax them and soften dynamic wrinkles like frown lines and crow's feet. Skin botox uses a much more diluted product, placed superficially across a wider area, to improve the quality of the skin itself. One relaxes movement, the other refines the surface. Many clients actually combine the two, using classic Botox for expression lines and skin botox for pores and glow.
What does skin botox treat?
Enlarged or visible pores.
Excess oil and shine, especially in the T-zone.
Fine surface lines and rough texture.
A dull, uneven surface that does not reflect light well.
Mild sweating in treated areas.
Because it addresses oil and pores rather than volume or deep wrinkles, skin botox is especially popular with clients who have combination or oily skin and want a smoother, more matte-yet-glowing finish.
How does skin botox create glass skin?
Glass skin depends on how evenly your skin reflects light. Large pores, excess oil and rough texture scatter light and make skin look dull. By gently relaxing the tiny muscles around pores and reducing oil production, skin botox tightens the appearance of pores and smooths the surface so light bounces back evenly. Combined with hydration-focused treatments, it helps produce that signature poreless, luminous quality. This is why we often include it in a broader glass-skin plan alongside a K-Beauty Facial or Sylfirm X.
Who is a good candidate for skin botox?
Skin botox suits most healthy adults who want smoother, less oily, more refined skin, and it is particularly loved by people with visible pores or shine. It is a subtle, natural treatment, so it appeals to clients who want an improvement in skin quality rather than a dramatic change. As with any botulinum treatment, it is not recommended during pregnancy or breastfeeding or with certain neuromuscular conditions, which we review at your consultation.
What to expect during treatment
After cleansing and numbing the skin, your injector delivers a series of very small, shallow injections across the treatment area. The appointment is quick, usually finished in about twenty minutes, and most clients describe only minor pinching. Because the product is superficial and diluted, it does not limit your expressions the way full-strength Botox in muscle would. You can return to normal activities right away, avoiding vigorous exercise and rubbing the area for the rest of the day.
How long do results last?
Most clients see their skin looking smoother and more refined within one to two weeks, with results typically lasting two to three months. Because it is a maintenance treatment, many people schedule it a few times a year, often timed before events or seasons when they want their skin at its best. Regular treatment can help sustain the refined, low-shine, glass-skin quality over time.
How much does skin botox cost in San Diego?
Skin botox is typically priced based on the amount of product used, and because it uses diluted toxin across the skin, pricing differs from standard per-unit Botox. At Seoule, we keep pricing transparent and confirm a personalized quote at your consultation, where we also discuss whether combining skin botox with a facial or other treatment would give you the best result for your budget.
Why get skin botox at Seoule in San Diego?
Skin botox is a genuinely Korean technique, and it rewards an injector who understands the artistry behind it. At Seoule, it is performed under Medical Director Dr. Lydia Park, MD, by injectors experienced in Korean-inspired dosing and glass-skin goals, a specialty not every med spa offers. We frequently combine it with Sylfirm X, Rejuran or a K-Beauty Facial for a complete, luminous result.
Skin botox aftercare and what to avoid
Aftercare for skin botox is simple, but following it protects your results. For the rest of the treatment day, avoid vigorous exercise, saunas and lying flat for several hours, and do not rub, massage or apply pressure to the treated skin, since the product is placed superficially and you want it to settle exactly where it was injected. Skip active skincare like retinoids and exfoliating acids for a day or two, keep skin hydrated, and use sunscreen as always. Mild redness or tiny bumps can appear briefly and settle quickly. Because skin botox is subtle by design, give it one to two weeks to reveal its full smoothing and pore-refining effect before judging the result, and plan your next session before an important event so your skin peaks at the right time.
Frequently asked questions
-
No. Because the product is diluted and placed superficially in the skin rather than deep in muscle, it refines the surface without limiting your natural expressions.
-
They are related but not identical. Baby Botox uses small doses in muscle for subtle wrinkle softening, while skin botox is placed superficially to refine pores, oil and texture. Many clients combine both.
-
Most clients notice smoother, more refined skin within one to two weeks, with results lasting about two to three months.
