information
aesPLLA® delivers gradual and long-lasting results. Visible improvement usually begins around 4 weeks after treatment, with effects continuing to develop over several months as collagen formation increases. Under optimal conditions, results may last up to 2–3 years, depending on patient age, lifestyle, metabolism, and injection technique. Maintenance sessions every 12–24 months can help sustain results. The delayed but enduring improvement distinguishes aesPLLA® from short-term fillers—making it ideal for patients seeking a slow, natural rejuvenation process.
