Not all skin areas are burdened to the same extent
by exogeneous factors. In addition, unusual physiological conditions
prevailing in some skin areas such as the hands and armpits affect
their need for protection and care.
The hands as a skin area with special demands
In the course of daily work in the house,
office and garden, the hands are especially burdened by contact with
water, surfactants and solvents. In addition, there are physiological
peculiarities which dictate a greater need for lipids. |
|
|
|
| |
|
|
|
| |
|
Frequent contact with water
can dry out the skin and severely impair the barrier function. Therefore
it is important that a suitable cleansing and care of the hands uses
substances that replace lost lipids. |
|
| |
|
|
|
| |
Excessive burdening of
the hands leads quickly to an overtaxing of the skin's protection
and repair systems and can result in damage to the skin's barrier
function. Damaged, cracked, dry and sensitive skin has an increased
tendency to develop eczema.
Therefore, it is important that a suitable cleansing and care of the
hands employs substances that replace lost lipids, maintain the physiological
pH and promote the regeneration process.
Deodorizing "care" to prevent body odour
The skin found in the armpits (axilla) has a pH of 6.5, which is well
over the physiological pH of 5.5. For this reason, this area is said
to have a physiological gap in the acid mantle. The higher pH influences
the growth of bacteria in the armpits. In the process of metabolising
sebum and sweat, larger amounts of intense odour-producing substances
are formed, which can lead to an unpleasant and strong body odour.
|
|
5 -10% of the population
are affected by hand eczema. In the working population, the proportion
of sufferers is 15 -35%. At 35%, hand eczema is the most commonly
reported occupational disease. |

The prevention of body
odours is a part of today's daily body-care, and there are a variety
of possible methods for controlling body odour:
 masking body odour
with perfume
controlling perspiration
with antiperspirants
controlling the growth
of bacteria by altering the pH or employing antiseptics
It is medically prudent to combine an antiseptic and antiperspirant
with an acid pH. Besides the efficacy of the medical deodorant, the
skin compatibility of the ingredients
is a decisive factor.
|
|
The skin compatibility
of deodorants plays an important role, especially for people with
sensitive skin, deodorant-intolerance or diseases such as neurodermatitis
or psoriasis. |

SUMMARY:
Certain skin areas, such as the hands and armpits, because
of exogeneous and physiological factors, have special demands
placed on them and need special care. Medical skin cleansing
and care products that are tailored to these needs, play an
important part in the restoration and maintenance of health
in these areas. |
