What is the recommended frequency and duration of maintenance for eye wrinkle treatments (Botox, Rejuran I, Eye Shurink)?
Botox is often considered for re-treatment about every 3 to 6 months as the muscle relaxation effect gradually wears off, while Rejuran I is usually performed several times at regular intervals initially, followed by maintenance care. Eye Shurink maintains its effects for a certain period as collagen regeneration continues after treatment, but the duration may vary depending on the degree of sagging.
