Rentox botulinum toxin A produced in Korea for softening of expression lines. Treatment mapping and units are individualized to anatomy and muscle strength; brands are not unit‑equivalent. Results typically appear within several days and are temporary, requiring periodic maintenance.
Individualized units and mapping per muscle and zone; intramuscular injections by licensed professionals only.
Common: injection‑site pain, bruising, headache. Rare: eyelid ptosis or asymmetry; urgent care for swallowing, speech or breathing problems.
Blocks acetylcholine release at neuromuscular junctions to relax targeted muscles temporarily.
Avoid alcohol 24h before and after procedures—vasodilation increases bruising and may slow recovery.
Not recommended in pregnancy—elective injectables lack robust safety data; defer until after delivery.
Not advised during breastfeeding—limited data on transfer via milk and infant safety; postpone elective procedures.
