Overview
Metazene — There’s no reason for anyone to suffer from acne.
Metazene is a gel containing three substances that act in
complementary ways against acne: niacinamide, Hamamelis extract,
and aloe. The gel is sold in a convenient 2-ounce bottle with a
dispensing pump that dispenses a measured amount with the
press of a finger.
Niacinamide, a B3 vitamin, has a scientifically documented track record as an anti-acne treatment:
- It suppresses inflammation, the cause of much of the skin disruption seen in acne;
- It reduces sebum production by hair follicles, limiting its availability to bacteria which thrive in it;
- It improves the skin’s water barrier function, which is impaired in acne-prone skin.
Extracts of Hamamelis virginiana have strong anti-inflammatory actions which appear to work synergistically with niacinamide
and aloe to produce a large effect.
Aloe, a gelatinous substance from the plant ‘Aloe vera’, is a
traditional herbal remedy used mainly for skin ailments. It
stimulates the growth and repair of the skin at the sites of
acne lesions (pimples). Aloe also has anti-inflammatory properties
that add to those of niacinamide and Hamamelis.
This is the formula that deals with the root causes of acne and does so without side effects. Users have been amazed at the
great results they have seen with this product.

What we can’t tell you
In the U.S. and some other industrialized countries,
government agencies like the U.S. Food and Drug Administration have
adopted
censorship as a method for intensifying their control over
supplement users and their suppliers. Thus, FDA regulations prohibit
us from telling you that any of our products are effective as
medical treatments, even if they are, in fact, effective.
Accordingly, we will limit our discussion of Metazene to a
brief summary of relevant research, and let you draw your own
conclusions
about what medical conditions it may be effective in treating.
Acne mythology
Until a few decades ago acne was difficult to treat
effectively. The causes were not understood and treatments were based
more on false premises and wishful thinking than on evidence of
success. For example, it was widely believed that acne sufferers
caused their condition through slipshod bathing habits or by
sexual activities. These and other myths about acne are still
being circulated and result in many sufferers not getting
treated.
One of the myths about acne is that it is a ‘merely’ cosmetic ailment that
isn’t worth treating since it isn’t life-threatening
and will go away eventually by itself. This is the attitude
taken by cheapskate parents who don’t want to spend money on their
offspring. The truth is that acne is a serious problem, both
psychologically and physically.
It need not be expensive to treat, and there is no good excuse for
anyone in the 21st Century being victimized by it.
Another myth is that acne can be treated by washing the face
vigorously. While washing can help the skin in some ways, it
is useless for preventing acne. Soap and water do not penetrate
the skin to where the problem is located.
Acne’s causes and treatments
Acne is caused by the following process:
- Testosterone and similar hormones (which increase in both
sexes during adolescence) cause oil glands in the skin’s pores and
hair follicles to become enlarged and overactive.
- The channels through which this oil normally travels to the
skin surface become clogged with proteins produced in the skin.
- Bacteria that normally live and multiply in this oil can no
longer escape to the surface. They continue to reproduce in the
clogged channels.
- Bacterial activity attracts cells of the immune system
which flock to the acne sites and release substances that irritate
and damage the skin.
- Bacteria and immune cells reproduce in the clogged
channels, enlarging the cavities and making cysts inside the skin.
- The cysts are temporary, but the skin damage they produce
can leave permanent scarring.
As described by Dr. Zarkov in an article
on this website, there are seven basic approaches to treating acne:
- Retinoid drugs (like tretinoin)
- Antibiotics (like tetracycline)
- Bactericides (like benzoyl peroxide)
- Steroidal hormones or hormone inhibitors (like estrogens or
cyproterone)
- Heat
- Light (intense blue/violet light or laser light)
- Anti-inflammatories
Most of these approaches have a downside:
- Retinoids make the skin dry, red, flakey, cracked, and
painful, and they cause severe birth defects.
- Antibiotics work poorly, and have distressing side effects
if used systemically.
- Bactericides also work poorly, are inconvenient, and can
damage clothing.
- Steroids and inhibitors often have undesired side effects,
and sometimes even damage the body permanently.
- Heat is not very effective.
- Light therapy is quite expensive and can cause burns.
The seventh approach to treating acne, anti-inflammatories,
has few if any negative side effects. Inexpensive anti-inflammatory
products are readily available without a prescription.
There are many anti-inflammatory substances to choose from;
they vary widely in effectiveness and convenience. They include:
- zinc
- azelaic acid
- tea tree oil
- ibuprofen and other anti-inflammatory drugs
- turmeric, witch hazel (Hamamelis), aloe, and other herbal
anti-inflammatories
- niacinamide
None of these anti-inflammatories are better than niacinamide
and Hamamelis in their ability to suppress acne without side
effects.
After an acne lesion (pimple) is inactivated, the skin’s
repair mechanisms come into play. Unfortunately, these work poorly
— that’s why we see so many adults with faces scarred from acne
episodes earlier in life. A good acne treatment should therefore
include a substance that aids in skin regeneration. Aloe is
such a substance.
Let’s look at what is known about these substances as acne
treatments.
Niacinamide
Niacinamide (aka ‘nicotinamide’) is a member of the vitamin
B3 family. In the body it is converted to NAD, which plays an
essential role in many biochemical reactions in all living
organisms. Niacinamide has been a part of the biochemistry of life
on Earth for more than a billion years.
Niacinamide’s powerful anti-acne activity, which has been
clearly demonstrated clinically,
results from several different actions it has in the skin:
- It suppresses inflammation
- It reduces sebum production by hair follicles.
- It improves the skin’s water barrier function,
which is impaired in acne-prone skin.
Niacinamide’s anti-inflammatory action is thought to stem
from its ability to decrease the production of pro-inflammatory
cytokines (signalling molecules),
reduce free radical levels,
and block the inflammatory actions of iodides.
Aside from its effects on acne, niacinamide also appears to
have a significant impact on skin aging. As one researcher describes
it, niacinamide “improves the surface structure, smoothes out
wrinkles and inhibits photocarcinogenesis”.
A clinical trial in 2005 concluded that 5% niacinamide applied to the
skin resulted in “reductions in fine lines and wrinkles,
hyperpigmented spots, red blotchiness, and skin sallowness
(yellowing)” and in improved elasticity.
Hamamelis extract
Hamamelis virginiana (aka ‘witch hazel’) was used by
native Americans in pre-Columbian times to treat many ailments. Witch
hazel twigs were steamed
in a sweat lodge and the smoky vapor settled on the skin and
was also inhaled. Today the twigs are chipped and extracted by
steam distillation to produce an oil containing flavonoids,
tannins, and other physiologically active components.
Hamamelis extract has significant activity against
inflammation, particularly when applied to the skin.
The mechanism for this activity is thought to involve the inhibition of
signalling molecules that mediate inflammation —
different signalling molecules than those that account for the
anti-inflammatory action of niacinamide.
Because the mechanisms of action of niacinamide and Hamamelis
involve different parts of the inflammatory process, these two
substances can work together synergistically to produce a large
effect. This would explain why Metazene, which uses the two
substances in combination, has such a remarkable impact on acne
in many people.
Aloe leaf extract
Aloe, a gelatinous substance from the plant Aloe
barbadensis (aka ‘Aloe vera’), is a traditional herbal remedy
used mainly for skin ailments.
In recent years scientific studies have shown its value in healing
wounded skin.
This activity seems to depend upon certain polysaccharides (chains of
sugar-like molecules) that regulate cytokines involved
in skin regeneration.
The main reason for Aloe’s inclusion as an ingredient in
Metazene is to stimulate the growth and repair of the skin at the
sites of acne lesions (pimples). However, aloe also has
anti-inflammatory properties that add to those of niacinamide and
Hamamelis.
No hidden ingredients
LifeLink has had queries from Metazene users who were
astonished by its effectiveness, asking whether the product contains
any ‘secret’ active ingredients not listed on the label. It
doesn’t. There are just three active ingredients: niacinamide,
Hamamelis extract, and aloe. They make a surprisingly powerful
anti-acne combination.
Conclusion
Is Metazene useful for the conditions and purposes mentioned
above? We aren’t allowed to tell you, so you should take a look
