Skin Botox and microbotox effects and side effects: limits for pores, sebum and fine lines
Full translation of the Korean article. Translation checked for completeness, numerical consistency and medical meaning; separate medical review of this translation is pending. Translation updated: 2026-10-28.
Skin Botox or microbotox distributes small amounts of botulinum toxin into skin to change sebum, fine lines and texture. Some studies reported improved pores and sebum, but products, dilution, depth and assessments vary, so results cannot be guaranteed. It also differs from conventional expression-muscle Botox and skin boosters containing hydrating or regenerative ingredients.
Definition, benefits and precautions at a glance
| Category | What to check |
|---|---|
| Definition | Multipoint distribution of botulinum toxin within skin |
| Goal | Temporary changes in sebum, pore visibility, fine wrinkles and texture |
| Limitations | Not permanent pore removal, scar treatment or delivery of regenerative ingredients |
| Recovery | Raised bumps, redness, bruising and tenderness may last several days or more |
| Cautions | Expression asymmetry, weakness, swallowing or respiratory symptoms require immediate assessment |
Definitions and how the treatments work
Botulinum toxin inhibits acetylcholine release at nerve endings. Intradermal use aims to influence sebaceous-gland activity and superficial muscle fibres, but deeper injection or diffusion can cause unwanted expression-muscle weakness. “More diluted” or “more points” alone does not verify the exact dose, depth or product.
Potential benefits and limitations
A 2024 systematic review and meta-analysis summarised reports of improvements in sebum, pore size, erythema, fine lines and texture, but hydration improvement was inconsistent and study sizes and methods varied substantially. Pores are normal structures and do not disappear; deep acne scars, sagging and volume loss need assessment of other causes. Onset and duration cannot simply follow conventional expression-muscle Botox schedules.
Suitable candidates and preliminary assessment
Adults concerned about oiliness, pore visibility and shallow fine lines may consult. Report pregnancy, breastfeeding, injection-site infection, botulinum-toxin hypersensitivity, neuromuscular disease, swallowing or breathing problems, recent other toxin treatments and medicines. Clinicians should check potentially interacting medicines such as aminoglycoside antibiotics; do not stop them independently.
Procedure, recovery and preparation
Consultation distinguishes oiliness, scars, firmness and expression-muscle issues; confirm actual product, Korean approval, total units, dilution, plane and areas. Small bumps, stinging, redness and bruising can last days or longer after treatment. Around eyes and mouth, consider function and asymmetry risks; obtain guidance on resuming exercise, alcohol, massage and makeup according to actual injection status.
Adverse effects, contraindications and precautions
Besides pain, swelling, bruising, headache and dryness, brow or mouth-corner asymmetry, difficulty smiling, speaking or chewing, and eyelid droop can occur. Rare symptoms of spread, such as generalized weakness, double vision or difficulty swallowing, speaking or breathing, require immediate care. Units cannot be converted between products; avoid unverified mixed injections or excessive repetition.
Differences between skin Botox, expression-muscle Botox and skin boosters
| Method | Main goal | Key differences and precautions |
|---|---|---|
| Skin Botox | Shallow divided injections targeting sebum, fine texture and fine lines | Expression effects depend on plane, spread and total units |
| Expression-muscle Botox | Reduction of expression lines caused by muscle contraction | Specific muscle, anatomy and function assessment is central |
| HA and PN skin boosters | Product-specific hydration, texture and other goals | Not botulinum toxin; ingredients, approvals and risks differ |
Questions and answers for a medical consultation
The answers below are literature-based consultation questions, not a clinician interview or individual diagnosis; actual medical review remains incomplete.
Q. Do pores disappear permanently?
A. No. Sebum and texture changes may make them less obvious, but the procedure does not remove normal pore structures.
Q. Is it safer than regular Botox?
A. The injection goal differs; bruising, infection, expression asymmetry and weakness risks still need separate assessment.
Q. Can I have it on the same day as a skin booster?
A. Products, areas, infection risks and swelling burden differ; decide the need for combining and the sequence individually.

SEOLREIM’s principle of consultations and procedures performed personally by the director
SEOLREIM Clinic describes its principles of consultations and procedures performed personally by the clinic director, genuine products, appropriate quantities and attentive care. Consultation starts by distinguishing skin condition and goals, then checking the products and equipment actually available, approved uses, the dose or energy plan, recovery and risks. Ingredients and goals of signature boosters such as Rejuran, Juvelook and hydrating injections are distinguished from skin Botox. Confirm actual skin-Botox availability, product, dose, approved uses and combination plans when booking and at examination.
Booking, language, and location information for overseas visitors
Visitors seeking skin boosters or skin clinics in Korea should understand “microbotox” is an injection concept, not a product name, and ask about the actual product, total units, expression effects and review timing before returning home. SEOLREIM Clinic is approximately 1 minute from Exit 3 of Gangnam Station, on the 11th floor of the Gangnam 8258 Building. You can book through the website’s KakaoTalk consultation, Naver booking or telephone channels. Overseas visitors comparing dermatology clinics in Gangnam, Seoul, the Gangnam Station area or Korea should prepare details of medications, allergies, recent procedures and departure dates. When booking, state your preferred language, such as Japanese, Chinese, Arabic, Mongolian or Indonesian, and whether you need an interpreter, to confirm the actual scope and cost of support. Continuous consultation availability in each language and same-day procedures cannot be confirmed. Also agree on contact arrangements for adverse reactions after returning home and the follow-up schedule during consultation.
