Description

Botulax 100UI — High-Purity Botulinum Toxin Type A

Botulax 100UI is a botulinum toxin type A product from Hugel, Inc., one of South Korea’s largest and most established pharmaceutical manufacturers. Hugel purifies each batch to over 99% using Size Exclusion High Performance Liquid Chromatography (SE-HPLC). This process supports consistent potency and high safety standards.

Botulax has built a strong international track record. In the United States, Hugel markets the same underlying formulation under the brand name Letybo. Letybo received FDA approval in 2024, reflecting the depth of clinical study behind the Botulax formulation.

How Botulax Is Made

Hugel purifies the active ingredient using Size Exclusion High Performance Liquid Chromatography, which removes impurities and supports consistent potency. The finished product arrives as a fine powder in a sterile vial, ready for reconstitution with 0.9% saline. Across multiple clinical trials, Botulax has shown stability, efficacy, and safety comparable to other established brands. It remains stable when stored at 2–8°C.

What Botulax Is Made Of

Clostridium Botulinum Toxin Type A	A purified neurotoxic protein that temporarily blocks nerve signals to targeted muscles, reducing dynamic facial wrinkles
Human Serum Albumin	A protein that stabilizes the toxin and helps maintain effectiveness after reconstitution
Sodium Chloride	Helps balance the solution’s pH and tonicity for safe injection

Mechanism of Action

Once injected, botulinum toxin type A blocks the release of acetylcholine, the neurotransmitter responsible for triggering muscle contraction. Because the treated muscle can no longer contract as forcefully, the movement that causes wrinkles decreases. As a result, expression lines soften, creating a more refreshed appearance. When a trained professional administers it correctly, the effect stays localized to the injected muscle and does not spread through the body.

Preparation & Dilution

Botulax comes as a fine powder that must be reconstituted with saline before use. Because the powder is so fine, the vial can look nearly empty. This is normal, and the full dose remains present.

Materials needed: 0.9% sterile saline, a sterile syringe (typically 30G), latex gloves, and alcohol swabs.

Saline Added (100U vial)	Resulting Concentration
1.0mL	10 units per 0.1mL
2.0mL	5 units per 0.1mL
2.5mL	4 units per 0.1mL
4.0mL	2.5 units per 0.1mL

1. Inspect the vial: it should be colorless and transparent with a small quantity of white or light yellow powder visible
2. Draw the saline into a syringe and slowly inject it into the vial
3. Gently swirl to mix — do not shake vigorously
4. Confirm the solution is clear and free of particles before drawing a dose
5. Store refrigerated at 2–8°C and use within 24 hours

Treatment Areas

Face:

• Glabellar lines (between the eyebrows)
• Forehead lines
• Crow’s feet
• Lower face and jawline (muscle contouring)
• Around the eyes (blepharospasm treatment)

Body:

• Areas affected by muscle spasticity
• Upper limbs (post-stroke spasticity)
• Lower limbs, including equinus foot deformity in children with cerebral palsy

Dosage & Technique

Dosage and injection technique vary by treatment area and patient condition. A licensed professional trained in botulinum toxin injection should determine the exact plan. General reference guidelines include:

• Benign essential blepharospasm: injected into the muscles surrounding the eyes in adult patients
• Post-stroke upper limb spasticity: injected into affected muscle groups in patients aged 20 and older
• Equinus foot deformity in cerebral palsy: administered to lower limb muscles in children aged 2 and older
• Glabellar lines: used to treat moderate to severe frown lines from repeated facial expression

Post-Treatment Care

• Avoid rubbing or massaging the treated area for at least 24 hours
• Stay upright and avoid lying down for 4 to 6 hours after treatment
• Avoid strenuous exercise for 24 to 48 hours
• Skip saunas, hot tubs, and excessive sun exposure for at least 24 hours
• Delay facials, microdermabrasion, or chemical peels for at least 1 week
• Mild redness, swelling, or bruising can occur and usually resolves within a few days

Course of Treatment

1 session	Typically enough to achieve visible wrinkle reduction
3–4 months	How long results from a single session generally last
3–6 months	Recommended interval for repeat treatment to maintain results

Most patients notice initial changes within a few weeks. Clinical follow-ups often confirm visible improvement at the 4, 6, and 12-week marks.

Precautions

• For use by licensed medical professionals only
• Contraindicated in patients with neuromuscular junction disorders, such as myasthenia gravis
• Contraindicated during pregnancy or breastfeeding
• Avoid in patients with active infection at the injection site
• Proper training in injection technique and facial anatomy is essential for safe use

Storage & Handling

• Store unopened vials refrigerated at 2–8°C
• Do not freeze
• Use within 24 hours after reconstitution; some data suggests stability up to 5 weeks under refrigeration, though 24 hours remains the standard recommendation

Botulinum toxin type A is a prescription medical product for use by licensed healthcare professionals only. Botulax itself is distinct from the FDA-approved Letybo product marketed in the United States. Availability may be restricted for US customers, so check current regulations before ordering.
