title: Collagen injections for aging skin lines (wrinkles).
abstract: It appears that benefit from collagen injections accrued to a large percentage of patients who responded to our questionnaire. It is interesting that 70% did not forward any information. Of those who reported benefit, the benefit lasted less than a year and was, in fact, within the 6-month range. Still, a large percentage of those responding were enthusiastic about further injections to correct their wrinkling.
