The treatment ususally begins to work within 24 to 48 hours,
and can last up to four months. The Food and Drug Administration
(FDA) approved the cosmetic use of Botulinum Toxin Type A for
the temporary relief of moderate to severe frown lines between
the brows and recommends that the procedure be performed no
more frequently than once every 3 months.
It is not known whether Botulinum A toxin can cause fetal harm
when administered to pregnant women or can affect reproduction
capabilities. It is also not known if Botulinum A toxin is excreted
in human milk. For these reasons, Botulinum A toxin should not
be used on pregnant or lactating women.
Dr. Iacono uses only FDA approved Botulinum Toxin Type A of
the highest certified purity.
