The number of PDO thread lift treatments needed to achieve the desired results varies from person to person and depends on a variety of factors unique to each patient, including:   • Desired outcomes • The condition being treated • The severity of the condition being treated • Individual physiology and metabolism • How the patient responds to the treatment • The duration of results   Although everyone experiences different outcomes, most people achieve the greatest benefit from one to three PDO thread lift treatments. How often one should schedule a follow-up appointment also varies, and largely depends on how long the initial results last. In most cases, results from the first treatment lasts around 6 to 12 months, although people with younger, healthier skin often reap the benefits for much longer.
