Description

Rentox 200UI — Premium Botulinum Toxin Type A

Rentox 200UI is a botulinum toxin type A product from Pharma Research Bio in South Korea. It carries KFDA approval. This vial delivers double the toxin content of the standard 100-unit vial, making it a practical option for larger treatment areas or higher-volume clinics.

Like the rest of the Rentox line, this vial ships as a fine, lyophilized powder. Because the powder is so fine, the vial can look nearly empty before reconstitution — this is normal.

What Rentox Is Made Of

Clostridium Botulinum Toxin Type A	The purified neurotoxin protein that temporarily relaxes targeted muscles
Human Serum Albumin	A stabilizing protein that helps maintain effectiveness during storage and after reconstitution
Sodium Chloride	Helps balance the solution’s pH and tonicity for safe injection

How Rentox Works

Once injected into a target muscle, botulinum toxin type A blocks the nerve signals responsible for muscle contraction. This temporarily reduces the muscle’s activity. As a result, the overlying skin’s movement-related wrinkles soften, and certain spasm-related conditions ease.

Preparation & Dilution

Practitioners dilute the vial with saline to reach a target concentration, adjusting the total saline volume based on the desired units per 0.1mL.

Saline Added (200U vial)	Resulting Concentration
2.0mL	10 units per 0.1mL
4.0mL	5 units per 0.1mL
5.0mL	4 units per 0.1mL
8.0mL	2.5 units per 0.1mL

Once reconstituted, use the solution within 24 hours and store it refrigerated at 2–8°C in the meantime.

Treatment Areas

Face:

• Forehead lines and glabellar lines
• Crow’s feet
• Vertical lip lines and marionette lines (“puppet wrinkles”)
• Nasolabial folds when smiling
• Facial asymmetry and facial paralysis-related correction

Body & Therapeutic:

• Hemifacial spasm and blepharospasm
• Focal spasticity of the wrist and hand in stroke patients
• Paralytic strabismus
• Hyperhidrosis of the face, hands, and underarms
• Multi-area treatment sessions given the higher unit count

Dosage & Injection Technique

For glabellar lines, a common protocol uses a 30G needle to inject 0.1mL per point across 5 sites — 2 injections in each corrugator muscle and 1 in the procerus muscle — for a total of 20 units. These muscles pull the brows together and downward, contributing to deep frown lines.

• When injecting below the orbital ridge (such as for crow’s feet), place a finger beneath the ridge to help prevent the product from migrating
• Direct the needle toward the upper center of the injection point, using a controlled volume per site
• Individual response varies by metabolism, antibody status, and lifestyle factors

Post-Treatment Care

• Remain upright for at least 4 hours after treatment to help prevent product migration
• Avoid touching, rubbing, or massaging the treated area for at least 24 hours
• Avoid applying makeup for 24 hours
• Avoid strenuous exercise, hot showers, saunas, and excessive sun exposure for 24 to 48 hours
• Avoid bending over or activities that cause a rush of blood to the head for up to 7 to 10 days
• Avoid antibiotics or other medications that affect blood clotting around the time of treatment, unless directed otherwise by a physician

Course of Treatment

2–3 days	Typical time to notice initial changes
Up to 2 weeks	Time to reach full visible effect
6–8 months	How long results from a single session generally last

Precautions

• For use by licensed medical professionals only
• Contraindicated in patients with neuromuscular junction disorders, such as myasthenia gravis, Lambert-Eaton syndrome, or ALS
• Contraindicated during pregnancy or breastfeeding
• Avoid in patients with active infection at the injection site
• Use caution with concurrent aminoglycoside, anticholinesterase, or curare-like medications
• Rare cases of distant toxin spread have been reported; always aspirate before injection and maintain emergency airway equipment on hand

Storage & Handling

• Store refrigerated at 2–8°C
• Do not freeze
• Use within 24 hours after reconstitution

How long do results last?
Results commonly last 6 to 8 months, which is longer than many comparable botulinum toxin products.

What’s the standard protocol for glabellar lines?
A common approach uses 20 units total, injected across 5 points — 2 in each corrugator muscle and 1 in the procerus — using a 30G needle.
