The ask in one line
This page does not state the reason as fact. Ask the clinic to explain its plan: how many visits, how far apart, and what is checked between them.
What to pin down
A series is a schedule. Get the schedule in writing.
- Ask how many visits the plan has.
- Ask how much time sits between visits.
- Ask what is reviewed at each visit before the next one is booked.
- Ask what happens if you stop partway through.
Where to read more
Four sources are listed for background. The laboratory study of poly-L-lactic acid particles and collagen synthesis and the multicenter retrospective study on immediate reconstitution of poly-L-lactic acid are research papers. The American Society for Dermatologic Surgery page on injectable poly-L-lactic acid is a patient-facing overview. The comparison of the physical and chemical properties of polylactic acid-based dermal fillers is another research paper. Look in each for any mention of repeat treatments, then ask the clinic how that applies to you.
Closing directive
The provider's plan for your treatment outranks a general page. Since this site reads plans on paper and never sees your skin, nothing here is medical advice.
