Ecolla is a poly-l-lactic acid plla and collagen stimulator. Formulated with a biocompatible and biodegradable synthetic polymer, the injectable stimulates collagen production to help volumize and smooth. Offering gradual results, the bio-stimulatory treatment works to correct the appearance of shallow to deep nasolabial fold contour deficiencies and facial wrinkles. Subsequent results may be observed from four weeks post-treatment, lasting up to 3 years.
