evaluate the skin whitening or
lightening effects of non-liposomal
and liposomal AL heartwood
extract, it was performed on
volunteer’s skin and measured the
skin color change by Chromameter.
After each subject was applied with
the lotion without the extract, and
lotions with the extract in both
liposomal and non-liposomal forms,
for 2 weeks, L* and ITA values
shown by the areas with the
products compared to the nonapplied
area was in the range of
0.3-0.8% and 2.0-3.0%, respecttively
which was not statistically
different. However, after 4-week
applications, it could be observed
the increasing of L* and ITA values
remarkably on the areas applied
with lotions containing liposomal and
non-liposomal AL heartwood extract
as shown in Figures 5 and 6.
