A patch test was carried out, "Skin White Serum" is applied
on skin-patch on the volunteers' arms, at x
number of times per day, for a continuous period
of 30 days. Observations for any signs of skin irritations
or skin reddening were carried out by Dr Jenson
and his group of researchers.
Results: No signs
of skin irritations or skin reddening occur at the
end of the test.
Two drops of "Skin White Serum" is applied on skin-patch
on the volunteers' left arms, at x number
of times per day, for a continuous period of 30
days. Two drops of Hydroquinones and Kojic Acid
99% concentrated solution was applied on skin-patch
on the right arms of the volunteers, at x number
of times per day, for a continuous period of 30
days.
Results: "Skin White
Serum" gives a more visible lightening result in
comparison with the Hydroquinones and Kojic Acid
99% concentrated solution. No skin irritations or
skin reddening was visible on the left arm, but
visible red blotches were visible on the right arms. |
