Today sadly the popularity of aromatherapy has declined and
the older practitioner pioneers are at retirement age. Aromatherapy has become
so common in the beauty world that it has become a standard offering normally
cast as a body massage treatment. Health benefits and skincare, have to a
degree, been marginalised by Governments and Trades Unions for various reasons
such as concerns over safety, training standards or simply the desire of the
medical establishment to control anything that suggests health improvement
without their intervention or control.
Aromatherapy is not the same as massage. It is not massage
with a pretty smell. You could argue that true aromatherapy has few ‘pretty’
smells anyway! Rather the combination of aromatic materials combined with
vegetable oils and then applied to the body has quite specific actions.
Skin is certainly more than a bag we live in. We do not
always consider our gut to be a skin and yet in fact the gut or lumen could be
argued to be ‘outside’ our body. Certainly it has several features in common
with skin. Firstly the acidic nature of the surface, which in healthy skin is pH
5.5 and only variable by small amounts corresponds to the gut maintaining
acidic conditions. Secondly the gut, as does the skin, has a colony of
microflora.
Our stomach has a pH as low as 1.5! It’s clearly understood
that this acid plays a key role in the digestion of proteins by activating
enzymes which break down long chains of amino acids. In the duodenum however
this gastric acid is neutralized by the
production of sodium bicarbonate which blocks gastric enzymes that have their
optima in very acidic conditions. The pH further along our digestive tract now
becomes around an average pH of 5-6 not so far off from our outer skin.
The enzyme factor
Enzymes are not only found in our gut but throughout our body system and on within and on our skin. These perfectly natural chemicals speed up the rate of, or cause, chemical reactions without being consumed in the reaction themselves, they are catalysts. Every enzyme in the body has a specific function so there is a mass of different enzymes.
Enzymes are not only found in our gut but throughout our body system and on within and on our skin. These perfectly natural chemicals speed up the rate of, or cause, chemical reactions without being consumed in the reaction themselves, they are catalysts. Every enzyme in the body has a specific function so there is a mass of different enzymes.
While there are many types of enzymes there are two primary
uses mentioned in relation to skin care - exfoliation and anti-inflammation. The
exfoliant action is considered more gentle and more effective than scrubs or
microdermabrasion , especially for oily skin.
The upper layer of skin
the corneum is mostly made of dead skin cells containing keratin protein. This
barrier layer is protective of the underlying newer active cells. Certain enzymes work by specifically breaking
down the keratin protein, resulting in smoother skin. The cosmetic industry
often promotes the idea of enzymatic exfoliation by adding fruit enzymes to
their products such as papain from papain. Such an approach ignores the ever
present natural enzymes on the skin. The question is whether our natural enzyme
or skin cycle is working properly and why should there be a need to use other
substances?
Other natural enzymatic activity includes the anti-ageing
scavenging of free radicals protecting skin against oxidative damage. Enzymatic
action can protect against damage from sun, environmental pollutants and
relieve skin conditions such as acne or eczema. This suggests that when skin is
not in optimum condition then the balance of our skin environment is not in
balance or as it should be.
For enzymes to
function certain conditions have to be present for them to work. As we have
seen first we have to have an acidic environment and an appropriate micro
climate or temperature. This applies inside and outside the skin. The foods we
eat eventually produce by enzymatic action our skin and connective tissue. Diet
affects skin health and appearance. As we age our production of enzymes slows
and this deficiency shows as the lack of cellular reproduction in wrinkling,
dryness and supportive tissue loss.
The Terrain
It becomes necessary to consider the optimisation of the
skin environment or in Aromatherapy what Franchomme termed the terrain or
ground of the skin. As a person who supports the idea of organic growing I can
readily understand the principle of the cultivation of the skin. Organic
growing is firstly about sustainability not just about the whether certain
chemicals have been applied or not.
The impact of chemical applications such as fertilizer or
herbicides on sustainability is the primary concern of organic growers. Soil
types or structure such as sandy to
heavy clay have a bearing on the potential crop yield and sustainability year
after year. Organic farming is often said to feed the soil but in fact it is
not the soil particle which is fed but the microflora, the symbiotic fungi,
bacteria which provides soil fertility and actions to give a life sustaining
environment for green plants which in turn feed all other life. The only
addition needed is water and hopefully this should fall from the sky.
Hence we should see correspondences to our skin. It too
requires in effect cultivation and an appreciation of the processes taking
place at the surface. The skin terrain needs optimum conditions and nutrition
provided by microfloral activity and a healthy dose of ever present enzymes to
insure conversion of materials available by application or recycling.
The Forest of the
Skin
The skin is a microbiome which under a microscope could be
compared to a forest of microorganisms which are ‘part’ of who we are. It is
this microbiome which largely contributes to our health and appearance. Just as
with agriculture certain species inhabit different parts of the body; some
favour moist areas others dry and still others more oil prone areas.
The bacteria which are generally beneficial to our skin rely
upon an acidic environment ideally pH
4-5.5. Under these conditions they thrive but not so pathogenic bacteria which
thrive under alkaline conditions. In alkaline conditions, friendly bacteria
cannot thrive and are readily lost. The skin reacts to alkaline conditions by
swelling slightly, feeling tight, so opening to invasion by foreign bacteria.
The outer skin cells are made of keratin, a very hard protein. Keratin must be
kept at an acid pH to maintain its hardness and so to keep the protective proteins
intact. Alkaline environments or substances soften and loosen the fibres of
keratin and create gaps in the protective covering. This allows more allergens,
irritants, bacteria and viruses to penetrate into the skin. Acne, skin
allergies and other skin problems become more severe when the skin becomes more
alkaline.
A good illustration is to think of the skin as a set of roof
tiles set tightly together. Any disruption to the skin pH, interferes with this
protective barrier, the ‘tiles’ move apart, opening up and intracellular cement
is dissolved, resulting in dehydration,
roughness, irritation and noticeable flaking. Skin is left defenceless and
susceptible to further environmental damage and above all dry! The pathogenis
bacteria can move in and the beneficial are lost.
Assuming that the average human has a colony of 1 trillion
bacteria plus a good supply of fungi this colonisation can get out of hand for
a variety of reasons. Good bacteria can under certain circumstances do more
harm than good. Certainly pathogenic bacteria are plentiful but the immune
system skin cells interacting with and
stimulated by bacteria usually deals with these. Desirable bacteria also
secrete anti microbial chemicals to kill rival pathogenic bacteria as well as
simply competing for the material we supply in the debris of our secretions and
dead and dying cells. Bacteria are great
recyclers.
Bathing in our sweat containing natural lactic acid, our
personal bacterial colony, the makeup of which is individual like a finger
print, will supply skin nutrients and condition our skin to its optimum.
The Aromatherapy Connection
Often this whole
system is referred to as the skin acid mantle or hydrolipid film. The
connection with aromatherapy begins to emerge. Hydrolats are well known for
their use on inflamed skin and are generally weakly acidic making them an ideal
replacement in skincare for neutral or hard water. Likewise the term lipid
refers to oils and fats which are the basis of many Aromatherapy treatments.
The skin acid mantle
consists of lactic acid and various amino acids from eccrine glands, free fatty
acids from sebum, amino acids, pyrrolidine carboxylic acid and urocanic acid from
the cornification of dead cells and process water from the deepest layers that
has reached the skin. This covering with its contingent bacteria makes for the
maintenance of enzymatic activity especially the enzymes responsible for the synthesis of
epidermal lipids. It could be argued that the skin is now
self-disinfecting.
Certainly we can see
why cleansing whether face, makeup removing, bathing or showering using soaps
and synthetic detergents is not necessarily as beneficial as we have been led
to believe! Swiss studies suggest that too much cleanliness can weaken the
body's immune system and cause allergies to develop.
The study of
essential oil pH has not greatly featured in literature but is generally
regarded as acidic. This refers back to the view that the antimicrobial activity
of essential oils may not be simply a question of antibiotic action but rather
the complementing of the skin acid mantle. In effect pathogenic bacteria may be
starved out and so the terrain altered in favour of friendly bacteria
rebalancing the microbiome.
Care of the ‘Environment’
The combination of
essential oils, hydrolats and vegetable oils can surely be considered superior
to many proprietary creams and lotions for general skincare as the objective is
not to add substances to the skin but rather to enhance and promote natural
skin activity.
Such an approach may
be considered a more organic pathway than products labelled as such. True
ingredients grown from an organic source are preferred by some consumers but
consideration should be given primarily to activity. If we view the skin as a
self-sustaining system then any cosmetic should be supportive rather than active within the
medical context. The addition of trained physical techniques such as certain
massage movements and frictions also support the function of body systems.
Relaxation or
stimulation, fundamental to Aromatherapy massage treatment also, as every
therapist knows, contributes to the ‘look’ of the skin following treatment.
Additionally we can add in the idea of the bioelectric field of the body and
skin which is affected by the frequency of essential oils. When
essential oils come into contact with our bodies, the frequency of our bodies
becomes raised so that we become inhospitable hosts to pathogenic
microorganisms but promoting a desirable and mutually beneficial environment
for friendly organisms.
Those associated with the Health & Beauty sector would
do well to consider the possibility of providing better product under their own
aegis rather than buying in the well known brands of skincare. Whilst the
Industry spends vast amounts of money on researching new ingredients and the
science behind the biological pathways of various substances, little attention
is paid to the fundamental activity to the surface of the skin itself. Aromatherapy
is much more than relaxing massage treatments and I hope the fashion wheel will
turn again to the use of essential oils. We already see a trend to small volume
bottles of very expensive treatment oils. Surely Aromatherapists can better,
through their education and hands on experience better such mass produced
products to the benefit of individual clients.
