Canadian Preparation-H Cream with Bio-Dyne (also known
as LYCD - Live Yeast Cell Derivative) is used for wrinkles because
it works. No fancy packaging, exotic smells, and sky high pricing.

have the same results. It worked for Granny but once the Bio-Dyne
was removed it was just another hemorrhoid cream.

Excerpt from p. 171 Testimonial Page
'Question: I was astonished
when my best friend told me that she used Preparation H on her face.
She said it helped smooth the wrinkles around her eyes.'
'Answer: Preparation H has been
used for lots of things besides hemorrhoids. We have heard of it
being employed for bed sores, itchy surgical scars, burns, dry
cracked finger, and yes, even wrinkles. The most familiar
store-bought hemorrhoid preparation is Preparation-H.'
'But it isn't what it used to be. For decades
Prep H contained two natural ingredients, live yeast cell derivative
(LYCD) and shark liver oil. No more. The Food and Drug
Administration reviewed the ingredients of hundreds of over the
counter medications. When they were done, a number of products were
reformulated, and many others simply disappeared. Preparation H was
one of those brands the FDA said had to be reformulated.'
'Forget the fact that millions of people loved
it and made it the best selling hemorrhoidal product on the market.
We used to make fun of shark liver oil and LYCD, but not anymore. We
discovered data that suggested LYCD accelerated wound healing.
People told us there was nothing better for their dry, cracked,
irritated skin or their hemorrhoids. We received countless
testimonials from folks who swore it was the only thing that
relieved the itching of their surgical scars. Many women even used
Prep H for wrinkles.'
'Now in the USA Prep-H contains an astringent
called phenylepherine instead of Bio-Dyne. We wish the FDA had not
meddled with a perfectly fine product. We have never been impressed
with the notion of using a vasoconstrictor on hemorrhoids, though
the FDA seems to think this makes sense. When phenylepherin wears
off it causes rebound dilation and congestion.'
It really must work or no one would use it!
No fancy jar, advertising, or high prices. Just the medically proven
healing ingredient called Bio-Dyne. The legends that encouraged
hundreds of models and actresses to overcome their squeamishness and
apply a hemorrhoid cream to their most valuable feature - their
face- came from the experience of using Prep-H with Bio-Dyne.
They would buy anything at any price but have settled on Prep-H.
They don't really want the world to know they are using hemorrhoid
cream on their faces. It doesn't smell like a cosmetic and it is not
packaged in a jar worth $10. It has the reputation of being used for
curing hemorrhoids. But it works and that is what really counts.
So why do those most concerned (some might even
say vain) about their appearances put Prep-H on their face and body?
The answer is that it works and you see the
results immediately. That is why make-up professionals recommend
their clients such as Conan O'Brien and Miss USA, use Canadian
The Science of Skin Healing with Bio-Dyne
We now know that Bio-Dyne is biologically active on skin cells.
There are clinical studies from the Cincinnati Burn Unit and Oregon
University School of Medicine to show that Bio-Dyne speeds wound
healing in burns and post surgically. The active ingredient has even
been isolated as a protein fraction containing a mixture of several
peptides Fortunately no one has told the Canadian manufacturer of
Prep-H to remove its Bio-Dyne. You will see the ingredient on the
label as Yeast as a live cell derivative (Bio-Dyne: Skin Respiratory
Factor) 1%. That is in addition to the Shark Liver Oil at 3% Making
Bio-Dyne Live Yeast Cell extract is a sensitive and expensive
process which provides the skin respiratory factor in the purest
You may have heard of similar factors in top of
the line cosmetics such as La Prairie. The discussion we have had
applies to using Prep-H for hemorrhoids or as a skin cream. Use
Prep-H Ointment for dry skin, chapped hands, or hemorrhoids. Use the
Prep-H Cream for wrinkles and the Prep-H Cooling Gel for
hemorrhoids. The Scientists have studied Prep-H- read it here:
"Topical application of yeast extract accelerates the wound
healing of diabetic mice." Crowe MJ, McNeill RB, Schlemm DJ,
Greenhalgh DG, Keller SJ. Shriners Hospitals for Children-Cincinnati
Alcoholic extracts of yeast have been used as
the active ingredient in medications under names such as
"tissue or skin respiratory factor," Biodyne (Sperti Drug
Co, Cincinnati, Ohio--now defunct), and live yeast cell derivative (LYCD).
Beneficial clinical results from the use of LYCD have been reported
for the treatment of burns, wounds, and hemorrhoids. The medicinal
effects of LYCD have recently been localized to a protein fraction
containing a mixture of several peptides. The effects of topical
application of the peptide mixture on wounds were examined in
diabetic mice, an animal model in which the healing process is
disrupted and delayed. Full-thickness wounds were created on the
backs of diabetic (DB) and non-diabetic (non-DB) mice. Half of the
DB and non-DB mice were treated with 0.05 mL of LYCD after wounding
and for 4 successive days. All other mice received vehicle. Wound
areas were measured at Day 0 and at 2-day intervals. Mice were
sacrificed at 3, 7, 10, 21, and 28 days post injury. Differences in
the extent and quality of healing appeared between DB mice receiving
LYCD and DB mice receiving vehicle by day 10 (P < .0001). By 24
days post injury, DB mice receiving LYCD had achieved 100% wound
closure, whereas DB mice receiving vehicle had achieved only 31.4%
wound closure. Histologic examination of wounds reflected improved
wound healing in DB mice receiving LYCD as compared with those
receiving vehicle. A topically applied yeast extract peptide mixture
significantly attenuates wound closure and the degree of cellular
reorganization of full-thickness accessional wounds of DB mice.

Peptides from live yeast cell derivative stimulate wound healing.
Bentley JP, Hunt TK, Weiss JB, Taylor CM, Hanson AN, Davies GH,
Department of Biochemistry, Oregon Health
Sciences University School of Medicine, Portland 97201. Live yeast
cell derivative is an alcoholic extract from yeast (Saccharomyces
cerevisiae) that has previously been shown by three groups of
workers to stimulate wound healing. Live yeast cell derivative is a
complex mixture, and it was not known which of its many components
was responsible for the biological activity. This study describes
the separation and analysis of the major components, one of which is
a peptide fraction that stimulates wound healing. The fraction
consists of a mixture of peptides from 6000 to 17,000 d. It causes
angiogenesis in a chick embryo yolk sac membrane assay and in a
rabbit cornea assay, and it dramatically stimulates wound healing in
the "Schilling/Hunt" wire mesh cylinder model at
concentrations 25-fold lower than those required for the intact live
yeast cell derivative. PMID: 1691911 [PubMed - indexed for MEDLINE]
