Margaret Ancira, PCA Founder, states,
"From the beginning, my concept
was to formulate a skin care line totally
diverse from the standard look good,
smell good, do nothing cosmetic products
that have been available to the consumer.
I also felt that they contained ingredients
that had the potential to provoke allergic
or sensitive reactions. It took a year
for our products to be formulated and
manufactured, but in 1991 PCA was born
and we haven't had time to look back
since."
PCA SKIN also insures that all of its
products are "chirally correct".
Chirality is a chemistry term that has
become more important in the cosmetic
industry. Certain molecules have right
and left "handedness" that
are considered mirror images of each
other without being super-imposable.
Some ingredients are a combination of
both 'hands', while other products utilize
one 'hand' or the other for different
formulations. The shapes of these molecules
as well as their 'handedness' will determine
their action in the body.
An ingredient being 'chirally correct'
indicates that the side of the molecule
that is most appropriate and effective
for the skin is being used in the formula.
One of the most important points associated
with chirality in the skin care and
pharmaceutical industries is the fact
that different parts of the body have
preferences for either right handed
or left handed molecules. Interestingly,
the less preferred 'hand' in a particular
situation is often referred to as 'inert',
although it can actually be responsible
for negative effects in the body. Using
only the chirally correct portion of
each ingredient insure higher activity
levels and better results. |
