If the fluid balance in the skin is disrupted, it
can cause dry skin to be sensitive to various physical
and chemical influences (Partogi, 2008). Dry skin is
a disorder on the surface of the skin due to reduced
fluid or oil content in the skin so that the moisture on
the surface of the skin layer decreases (Nuzantry,
2015). Skin hydration decreases due to decreased
stratum corneum barrier function and increased water
loss through diffusion through the epidermis or
TEWL (Black et al., 2005). According to the US
Census Bureau estimated in the United States in 2004,
there were 3.1% or 8.4 million people suffering from
skin dryness. It is estimated that the Indonesian
population who suffered skin dryness amounted to
7,392,041 in 2004. This data was obtained by
statistical extrapolation based on data in the United
States, the United Kingdom, and Australia (Health
Grade, 2009).Dry skin is a problem that is often faced
by almost all people in all parts of the world. Dry skin
will look dull, feel rough, scaly, wrinkled, and less
elastic than normal skin (Draelos, 2018).
Skin hydration decreases due to decreased
barrier function of the stratum corneum and increased
diffusion of water loss through the epidermis or
TEWL (Black et al., 2005). Skin hydration has a
major effect on maintaining homeostasis on the
surface of the skin and maintaining its elasticity.
Low-hydration skin elasticity will be reduced, the
skin will become dry and the surface is easily
damaged. However, changes in the epidermal fat
component of the skin can also cause xerosis. Some
experts believe that the incidence of dry skin has
increased in recent years because people often take a
shower using hot water, foaming cleansers, bubble
baths, and bath salts, which damage the skin barrier
by stripping the lipid component on the surface of the
skin. Soap, detergent, and hard water can eliminate a
healthy and normal skin barrier (Baumann, 2009).
Various studies have been carried out to obtain
optimal dry skin management. One of them is by
producing moisturizers that effectively increase the
water content in the stratum corneum and hydrate it.
Nuzantry et al., (2015) investigated aloe vera extract
and olive oil as a basic ingredient in moisturizing base
formulations and reported that the mixture of aloe
vera extract and olive oil in moisturizing formulations
is effective in skin dryness. Moisturizers are complex
formulations designed to improve the hydration
mechanism of the skin and maintain the structure and
function of the skin from various influences such as
dry air, sunlight, old age, temperature, various skin
diseases and diseases that can accelerate water
evaporation (Nuzantry, 2015).
Moisturizers has been generally used to
relieve dry skin by increasing barrier repair, creating
temporary artificial barriers, and restoring skin
softness. Scientifically, moisturizing treatment
involves four processes, namely repairing the skin
barrier, increasing water content, reducing trans
epidermal water loss (TEWL), and restoring lipid's
water barrier function (Klein, 2005). The basic
components of a moisturizer consist of an occlusive,
humectant and emollient. Occlusive is a substance to
coat the stratum corneum and reduce TEWL.
Humectants are useful for the skin hydration process.
While emollients are substances that are added to
cosmetics to make skin soft and smooth. Other
components are antioxidants, vitamins, essential fatty
acids, lipoic acid, linoleic acid and herbal extracts
(Lodén, 2011).
Previously have been reported that four
commercial moisturizer products of different brands
were tested on volar forearm region of healthy human
female volunteers. This study was conducted for a
period of 30 days with 0, 7, and 30 days as time points
of analysis. The results of this study clearly indicate
that not all the moisturizer products hydrate the skin
to the expected levels, and this extent of skin
hydration varies with duration of application of these
products (Tippavajhala et. al. 2018). Another studies
by Engebretsen 2018 reported that Epidermal
deficiency of filaggrin, and the derived natural
moisturizing factors (NMFs), is associated with
increased risk of atopic dermatitis (AD). While
filaggrin gene mutations cause filaggrin deficiency,
there is limited insight into the causative
environmental factors. NMFs levels are decreased
along with increased secretion of various skin
cytokines in healthy individuals. Our data highlight
environmental factors that might play a role in AD
pathophysiology (Engebretsen et.al.2018).
Saccharide isomerate (SI) is a muco-
polysaccharide carbohydrate complexes that are
similar as those found in the human skin's stratum
corneum. The active ingredient saccharide isomerate
in the epidermis will form hyaluronic or hyaluronic
acid. Saccharide isomerate is one of the answers to
the development of glycobiology. Saccharide
isomerate can retain moisture by increasing the water
content in the stratum corneum even in low air
humidity. Saccharide isomerates can also bind to the
skin even in very low pH conditions (Pentapharm,
2009).
The phenomenon of peeling skin manifests
itself as one of the conditions such as dehydrated skin,
loss of moisture retention and natural protective film
possibly due to the use of strong cleansing products
or harmful effects of the environment, i.e. chemicals.
When this corneocyte layer is damaged, they will lose
their ability to bind, losing NMF leading to the
phenomenon of peeling in each section and an
opportunity for more harmful thing to enter into our
bodies possibly causing different types of atopic
dermatitis. Extending the time of injury due to
