Moisturising
Your Skin:
How Do Moisturisers
Work?
Moisturisers are
cosmetic products which to some extent provide a practical answer to
problems of water loss from the skin.Though water is the missing
ingredient, in dry skins, application of water alone is not the
solution as this has only a temporary effect.Though oil is equally
essential(it serves to hold water onto the skin surface), it alone
also can't moisturise the skin.
Moisturisers, therefore, combine both water and oil.This not
only replaces some of the water lost from the skin, but more
importantly prevents its loss to the surroundings.There are several
moisturising products available in the market.They all fall,
basically, into 2 main types: oil-in-water emulsions and
water-in-oil emulsions.The oil-in-water moisturisers sometimes also
contain substances called humectants which attract water from the
surroundings, but this may have its own disadvantage because
humectants may sometimes absorb too much water from the skin itself
thereby increasing its dryness.A commonly used humectant is
glycerine.Newer ingredients have been added to increase the efficacy
of this group of moisturisers, but still their effect remains
temporary.The second category of moisturisers comprise newer
water-in-oil emulsions.They are marketed generally as creams or
lotions.Being oil-based products, these trap moisture in the skin by
forming an occlusive film on the skin surface; this forms a barrier
retarding water loss. Many of these products are also called
anti-dehydrating creams.
How To Choose Your
Moisturiser:
Choosing the
moisturiser to suit your skin type is very very important.The
proportion of oil varies according to the type of skin for which the
product is formulated.So read the instructions on the label of the
products.Generally speaking, products meant for well-balanced normal
skins are water-based, containing a little oil.Those designed for
dry skins make up for the lack of oil on the skin, by adding to the
akin.Humectants like glycerine and lactic acid, are also added to
retain moisture.
Moisturisers are, generally, not to be used on oily skins,
because they can cause spots.But today safe synthetic chemicals are
available-these oil-free moisturisers do not contain any
mineral-oils, vegetable oils or animal fat, but contain either
modified oils or other synthetic ingredients.Use them on patches of
dryness caused by excessive use of anti-pimple remedies, yet don't
use them too liberally.Now, newer light non-greasy creams and
lotions are also available-these are as effective as the heavy,
thick and greasy creams and are competitively priced.They are the
best type to be worn under make-up, as they give a superb finish to
the make-up.
Is It Worth Using A Moisturiser
Regularly?
Yes,
regular use of a suitable moisturiser does benefit your skin.By
guarding against the excessive loss of water, these agents protect
the skin against the drying influences of the environment- the
effects of the sun, cold and heat.A moisturiser is particularly
helpful for naturally dry skins, but whatever be your skin type, a
moisturiser does compensate for the deficiencies in the natural
oil-film and keeps your skin lubricated making it soft, smooth and
looking more youthful.
Further, moisturisers give a
smooth finish to make-up.Putting on a light moisturising cream will
make make-up much easier to apply and reduce the risk of dragging
the skin.Most dermatologists agree that moisturisers effectively
combat skin dryness and make the skin soft and supple.But the role
of special ingredients, like vitamins, proteins, collagen and
hormones, in many of the expensive creams is quite doubtful.In fact,
it is only the simple lubricating action of the ingredients in the
creams that do any good.So using exotic oils(such as deer oil)
istead of ordinary oils, will not make the moisturiser any more
effective, though it will add enormously to the cost.However,
certain natural and sythetic substances, humectants-like urea,
lactic acid, and phospholipids, might improve the efficacy of
moisturisers as they increase the hydration of the skin.
