As we are learn more about our skin, the public is
becoming more ingredient conscious. Understanding what
substances make up a product can be helpful. If you have
a known allergy, your dermatologist or allergist can
help you determine other related ingredients. It will
also help you to understand what makes a product greasy,
irritating, acne-flaring, drying and hopefully those
that are effective, too! This is not meant to be a
complete list of every ingredient used in the industry,
but will attempt to cover the most popular individual
ingredients and categories that have gained recognition
as of late. Use this as a handy reference by which to
gain information as you learn more about your skin
through our site. This list shall be continually
expanded.

The Fair Packaging and Labeling Act (FP&L) has set
guidelines regulating ingredient listings. Listings
begin with the ingredient present in the largest
concentration (often times the necessary vehicles water
or SD alcohol 40) and moves downward to often times
trace elements. The vehicle is responsible to carry the
other ingredients, creating the actual suspension, so
just because water may potentially make up most of a
product, it is usually for good reason. and etc. |

The Wonders of Hyaluronic
Acid: Nature¡¯s First Cosmeceutical by Dr. Dennis Gross |
My
dermatologic practice has clearly demonstrated to me
that skin aging is not just a loss of collagen, but also
a loss of water. It¡¯s the loss of both that accounts for
fine lines, deeper wrinkles, folds and even sagging of
the skin as we age. Collagen, no doubt, is the primary
structural protein giving skin its firmness. But, if
collagen serves as the bricks in skin structure, then hyaluronic acid clearly serves as the mortar.
A Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings)is a natural constituent of skin and has the
remarkable ability to hold nearly one thousand times its
weight in water. That¡¯s how H-A contributes to the
thickness of skin: it doesn¡¯t build like collagen, it
inflates with water.
H-A is also known as sodium hyaluronate and is a
macromolecule officially classified in the chemical
group known as a glycosaminoglycan. Collagen and H-A are,
interestingly enough, both produced by the same dermal
skin cells called fibroblasts. Born of the same mother
cell, both collagen and HA
(Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) degenerate in human skin with
aging and sun damage. Hormone depletion, lowered
estrogen and menopause all cause the manufacturing of
H-A
to diminish.
HA (Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) is probably the most underrated and powerful
ingredient the cosmaceutical industry has yet to fully
exploit. It has been the focus of much of my own
research. The key benefit and added beauty
HA (Hyaluronic Acid Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) brings to
skin is defined by the word turgid: the optimal
plumpness of skin achieved by the retention of water.
When skin is optimally turgid, it appears smoother and
plumper. HA (Hyaluronic Acid(Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) achieves this effect because it is one of
the most important regulators of water metabolism in the
skin. To appreciate how it beautifies the skin, one must
explore H-A¡¯s different mechanisms of action on the
epidermis and dermis.
When applied directly to the epidermis via topical
products, such as creams and gels,HA
(Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) hydrates the skin
as a humectant. It literally attracts air born water
vapor into the skin and retains water delivered to the
skin by the circulation. Because of this mechanism, the
dermatologic effect of moisturization is superior to
what could be achieved by the typical moisturizer
composed only of a routine oil- and-water mixture.
HA (Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) is
a key ingredient that is fortunately highly soluble and
adds another dimension to product design. The truth is
that a moisturizer without a humectant only provides the
skin with the additional water barely contained in that
small amount of product one spreads over their skin.
HA (Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) also provides another key benefit by preventing the
evaporation of water from the skin. Clinical research on
dry skin measures a key index known as trans-epidermal
water-loss (TEWL). Think of it as a measurement of the
skin¡¯s inability to retain water which is lost by
evaporation. Studies clearly demonstrate that sun
damaged skin take on its chronic dry skin appearance
because of its associated increase TEWL. While this
condition may also involve an abnormal lack of
exfoliation, HA (Hyaluronic Acid
(Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) should be a key therapeutic ingredient
in one¡¯s skincare regimen because humectants ordinarily
synthesized by the skin are reduced as a consequence of
sun damage.
The skin¡¯s natural HA (Hyaluronic Acid
(Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) may also be lost by mistakes made
in one¡¯s cleansing routine. Whereas aging and sun damage
reduce the skin¡¯s ability to retain water, cleansing may
strip the skin of its own humectants and oils beyond the
skin¡¯s ability to manufacture them. Generally, bar soap
is more drying than non-soap liquid cleansers, and soapy
liquid cleansers are often the most drying of all.
Everyone knows when their skin is severely dry simply
because it looks flaky. Educating your clients on how to
prevent dryness is more challenging. Facial skin may be
especially tricky to diagnose because it may be dry and
yet show no flaking. Many people simply do not know
whether their cleansing routine is right for them. And
what¡¯s right for you today may change with the seasons,
your age or even with what other products you use. After
years of practice, I have learned the best overall way
to determine if someone is at risk of dryness is to
simply ask whether their skin, especially their face,
feels tight and uncomfortable thirty seconds after
toweling dry. If the answer is yes, switching to a
milder cleanser is recommended. Remember, the skin is an
insensible organ, which means we are not aware of it
unless something is wrong. After several episodes of
feeling tight, true dryness and even irritation may
result. Sometimes simply using less soap is sufficient
(I constantly tell patients soap is not like shampoo so
don¡¯t lather up the same way) or simply changing from a
scrub cleanser to a gentle one does the trick.
Thus far we have focused on the role of
HA (Hyaluronic Acid
(Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) in the
superficial epidermal portion of the skin where its
chief function is to moisturize. But
H-Ais also
naturally found in the deeper dermal portion of the skin
where its major role is to increase thickness
(turgidity) by holding water. Unfortunately, applying
HA (Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings)
topically has its limitations because only a limited
amount can penetrate.H-A is a thick viscous substance
which feels sticky, even gummy, on the skin if overly
concentrated in a topical product. So far the only
solution the beauty industry has for getting H-A into the
deeper skin is via injection administered by physicians.
Although, as discussed below, my patented research
indicates that there is yet another method to deliver
H-A
into deeper skin either via an esthetician or an at-home
product.
Injectible HA (Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) is now a very popular procedure performed
by dermatologists and plastic surgeons and is probably
another contributing factor to the statistical decline
of some plastic surgery procedures (such as brow lifts)
performed in recent years. Commercially available forms
of injectible HA (Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) are sold as Restylane, Hylaform and
Captique. Along with Botox injection, injectible
procedures have been increasing steadily in the U.S.
since gaining FDA approval several years ago.
HA(Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) injected into the dermal skin acts as a filler to
plump and elevate wrinkles, folds, and even depressed
acne scars. The nasolabial fold is the most popular use
of the material, although it may be used to plump any
deeper defects in the face such as the perioral or brow
areas. A thinner version of Restylane is available for
fine lines such as the crow¡¯s feet around the eyes.
Injectible collagen (Zyderm and Zyplast) was the first
synthetic filler approved by the FDA in the 1980s and is
still widely used. In my experience, injectible
HA ( Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) does
offer several advantages over its predecessor. Injectible
HA(Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) is more natural and hypoallergenic and
unlike Zyderm and Zyplast does not require skin testing
before treatments. Some newer versions of injectible
collagen (Cosmoderm) are also hypoallergenic as they are
derived from cadavers.
A typical patient receiving Restylane is told to avoid
taking any aspirin products or Vitamin E for at least
three days prior to the procedure to avoid bruising.Upon
entering the treatment room, topical anesthesia is
applied for fifteen to twenty minutes to minimize the
pain from the injection. Some mild pain is still usually
felt from the procedure due to the depth of the
injection. Multiple shots with a fine needle are used to
fill the lines or grooves and the area is then massaged
for several minutes to avoid lumping and assure a smooth
correction. I find ice packs applied at the end reduces
swelling (which is minimal) and reduces localized
bruising that is still the number one risk of the
procedure which can last several days. The correction is
immediate making those who like instant gratification
especially happy. How long do the results last? Most
manufacturers advertise the benefits are seen for six
months. In my experience this is generally true,
although the improvement starts to decline after four
months.
My amazement with HA(Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) motivated me to conduct my own
research through my company MD Skincare. The central
issue, you now understand, is this: applied topically to
the epidermis works as a great moisturizer but for it
to plump it must be injected into the dermis. Could
another delivery system be developed that gives
HA(Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings)
better penetration, without injecting it, allowing it to
both hydrate and firm skin? The answer is yes, and here
is what I discovered. A thick gel of concentrated can
be applied to the face and massaged in with water.
Because all ingredients have deeper penetration when
under occlusion such as a bandage, I find using a mask
over HA( Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) similarly deepens its penetration exceptionally
well. Furthermore, if the mask is self-heating then it
will also bring a burst of blood flow to the skin which
contains additional water from the circulatory system.
By simple osmosis the water is attracted to the
which
clings to it at a rate of one thousand times its weight.
Because the HA(Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) is deeper in the skin when the water
appears, H-A not only moisturizes but also acts as a
filler to plump and firm the skin. The plumping-effect
is dramatic and, although less than if injected, can be
achieved by the hands of an esthetician or with an
at-home product.
In summary, HA(Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) is the wonder drug nature has to offer
and is a star in the cosmeceutical industry. Few
ingredients are as safe, versatile and effective. A
natural constituent of skin itself, when combined with
laboratory technology
HA(Hyaluronic Acid (Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) enhances moisture and plumps
skin. It¡¯s the newly discovered long lost cousin to
collagen, and partner to another ingredient fundamental
to beauty and life itself: water!

HA Production |
Hyaluronic acid (also called Hyaluronan or HA)
is an
element of the connective tissue that acts as a cushion
and lubricate. Hyaluronan (Hyaluronic Acid,HA,sodium hyaluronate)occurs in copious amounts
throughout the body, especially in places where people
with hereditary connective tissue disorders have
problems, such as joints, heart valves and eyes. Hyaluronic acid abnormalities are a common thread in
connective tissue disorders. There are also common
biochemical deviations in most of the individual
features of connective tissue disorders such as mitral
valve prolapse, TMJ, osteoarthritis, and keratoconus.
Hyaluronic Acid is present in every tissue of the body.
Retention of water is one of the most important
biological functions of Hyaluronic acid (HA,Hyaluronan,sodium hyaluronate). It is also
critical in providing nutrients and removing waste from
cells that do not have a direct blood supply, such as
cartilage cells. If the amount of
Hyaluronic acid (HA,Hyaluronan,sodium hyaluronate)
depletes, nutrients cannot be moved into these cells and
waste cannot be eliminated from cells.H-A is found in
the synovial joint fluid, the vitreous humor of the eye,
the cartilage, blood vessels, extracellular matrix, skin
and the umbilical cord.
Hyaluronic acid ((HA,Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) has been nicknamed the "key to the
fountain of youth" because it has been noted that some
people who ingest a lot of H-A in their diets
tend to live longer. Some Japanese villagers have been
known to live to ripe old ages due to the use of HA
Hyaluronic acid for use by humans is derived from
rooster combs, which provide the purest form of
Hyaluronic
acid ((HA,Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) available.
Hyaluronic Acid (HA,Hyaluronan,sodium hyaluronate) Benefits
• moisturizes skin from the inside out, smoothing out
wrinkles in the process
• helps people who need to ease the flexing of their
joints, especially their knees, by restoring cushioning
to their joints
• suitable for men and women in their 30s and 40s who
are beginning to see the first signs of aging
• suitable for seniors who have established joint
conditions |

Sources of Hyaluronan |
Since the beginning of time, people have been searching
for an effective way to reverse the aging process.
H-A is seen by many to be the Fountain of
Youth, and there are plenty of natural sources available
to make it part of a healthy diet.
Hyaluronic Acid (HA,Hyaluronan,sodium hyaluronate) Facts
H-A is found in the connective tissues of
humans and animals. It plays a key role in cushioning
and lubricating the body and is abundant in the eyes,
joints and heart valves. A powerful antioxidant,
H-A is perhaps best known for its ability to
bond water to tissue.
Hyaluronic Acid (HA,Hyaluronan,sodium hyaluronate) Benefits
The body's hyaluro-nic acid levels decrease with age. In
theory, sustaining optimal Hyaluronic acid levels could
retard the aging process, prolong a youthful appearance,
and sustain life.
A prominent component in synovial fluid,
helps lubricate the joints and fight arthritis. It can
be taken in capsule form or injected directly into the
joints to relieve pain, helping even old bones feel
young.
Hyaluronic acid ((HA,Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings), with its remarkable ability to keep
tissue moist, is particularly effective in treating
wrinkles and dry skin. It maintains skin elasticity and
even speeds up the healing process for wounds and scars.
is also believed to promote healthy eyes
and heart valve function.
Hyaluronic Acid (HA,Hyaluronan,sodium hyaluronate) Sources
Since HA is found in the connective tissue
of animals, consuming animal products is believed to be
the best natural source available. Chicken soup made
from boiling the bones and skin of chickens can be a
surprisingly rich source for hyaluronic acid. Even most
hyaluronic acid supplements are made from rooster combs.
Other options exist for vegetarians. Magnesium is needed
in the body to synthesize Hyaluronic acid, so consuming
foods rich in magnesium, like avocados, broccoli,
peanuts, potatoes, soy and spinach can keep Hyaluronic
acid levels from dropping too low.
Estrogen and Hyaluronic acid (HA,Hyaluronan,sodium hyaluronate) have somewhat of a
symbiotic relationship. When the level of one rises, so
does the level of the other. Soy products, like tofu and
soy beans, have been shown to increase estrogen levels,
making them an indirect source for hyaluronic acid.
Zinc deficiencies seem to coincide with low Hyaluronic
acid. Consuming brown rice, peanuts, potatoes, pumpkin
seeds and other zinc-rich foods could alleviate the
problem.
Hyaluronic Acid (HA,Hyaluronan,sodium hyaluronate) Geography
Yazuri Hara, a small village in Japan, is known for its
youthful citizens who live well into their 80s and 90s
with virtually no wrinkles and few health complaints.
Studies have indicated they have naturally high levels
of H-A due to diets rich in starchy root
vegetables like sweet potatoes and other local forms of
potato roots.
Hyaluronic Acid (HA,Hyaluronan,sodium hyaluronate) Warnings
Researchers at the University of California San
Francisco have discovered abnormally high levels of
Hyaluronic acid could contribute to tumor progression in
breast cancer. The University of Minnesota's Department
of Surgery has found similar results regarding colon
cancer. |

Vegetable Food Sources for Hyaluronate |
Hyaluronic acid (HA,Hyaluronan,sodium hyaluronate) is a naturally occurring chemical created
by the body that provides cushioning for joints and
connective tissues. Individuals with insufficient
amounts of Hyaluronic acid (HA,Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) may experience issues with
osteoarthritis, TMJ, detached retinas, poor scar
formation, wrinkles, fibromyalgia, glaucoma or heart
valves.
H-A is mostly found in animals, though there
are a variety of non-meat options that can help increase hyaluronic acid
( (HA,Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings)production in the body.
Soy
Because of its tendency to increase levels of estrogen
in the body--which in turn increases levels of
hyaluronic acid--soy is a great vegetable option.
Soy beans in their original baby form are edamame. Tofu,
or soy bean curd, is the most versatile soy food. Soy
milk, soy ice cream or soy yogurt are a few other
options. Soy can also be found as textured vegetable
protein.
Magnesium
Magnesium is essential for Hyaluronic acid ((HA,Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) synthesis; a
lack of magnesium in the diet may be part of the cause
of low Hyaluronic acid levels.
Soy is rich in magnesium, as is spinach, green beans,
broccoli, cauliflower, asparagus, potatoes, green
lettuce and carrots.
A variety of magnesium-rich fruits are available:
apples, bananas, strawberries, tomatoes, avocados,
pineapples, oranges, papayas, melons, peaches and pears.
Legumes such as kidney beans, pinto beans, black-eyed
peas and lentils are rich in magnesium. Peanuts and
almonds also contain magnesium.
Zinc
Low levels of Hyaluronic acid ((HA,Hyaluronan,sodium hyaluronate):Facts,Benefits,Sources,Geography,Warnings) has also been found in
individuals with low zinc levels.
Zinc is utilized for a variety of bodily processes.
Usually associated with foods rich in protein, such as
beef, lamb, pork or chicken, there are a few non-meat
options.
The best vegetable source for zinc is pumpkin seeds.
Potatoes are also a good source, as is yeast, peanuts,
beans, whole grains or brown rice. |
