- Skin Types And Skin Care -
It is really important for you to be able to identify your skin type.This is to enable you to look
after your skin correctly.Also the selection of your cosmetics is, to a considerable extent,
influenced by your skin type.Although no two skins are exactly similar most have
characteristics which enable them to be grouped into one of the following typesry skin,
Normal skin, Combination skin and Oily skin.
To determine your skin type, wash your face with a mild face wash.Then, after 30 minutes,
press a clean tissue against your forehead, nose, cheeks and chin.If the tissue shows no trace
of oil, then you have dry skin.Dry skin looks rough and is prone to premature fine lines and
wrinkles.If your skin is oily in some parts but dry in others, then you have combination
skin.Normal skin usually looks smooth and is not prone to break outs.Oily skin feels oily to
touch and tends to shine.Oily skin is also prone to blackheads and pimples.A sensitive skin
needs special care, as it may be sensitive to some ingredients found in popular
cosmetics.Those with sensitive skin should always use beauty aids that are hypoallergenic to
protect their skin from allergic reactions.A regular skin care programme, adapted to the needs
of your particular skin type, goes a long way in keeping your skin radiant and problem free.
Dry Skin -
Dry skin needs extra care, as it is prone to fine lines and wrinkles.This is especially true
during the winter months when it feels even drier and may feel too taut or may even flake.A
few measures help alleviate dryness and keep your skin supple and, at the same time, guard
against premature aging.
1. Always wash your face with a mild, soap-free face wash.Never use soap, as that would
further strip your skin of natural oil.
2. Always use a moisturiser during the day.Use upward,circular motion to lightly massage the
moisturiser into your face.Make sure not to pull or tug your skin.
3. You should consider using a night cream before going to bed at night.It is advisable to use a
cream that contains Alpha Hydroxy Acids(or AHA's, as they're commonly known).AHA's are
derived from sources such as milk, fruit and sugar-cane.These acids gently exfoliate the dry,
dead, outermost layers of skin while they moisturise the newly revealed layers.They greatly
benefit complexions that look dull, dry or flaky and they give your skin a beautiful glow.
4. Both AHA and Vitamin C help reduce fine lines and other signs of aging.Thus, you may
get good results quickly by using a moisturiser or cream that contains Vitamin C during the
day and an AHA-based night cream.Most known brands have moisturisers and creams that
contain these.
5. If you have dry skin that tends to flake off, looks red and has some itchy patches that scab,
consult your doctor to rule out eczema.Eczema, also known as atopic dermititis, is generally
considered to be a hereditary condition that can occur throughout the year.Other causes of
eczema can be fabrics such as wool, some skin-care products or detergents etc.Your doctor
may prescribe a cream to soothe the redness and irritation.Non-irriating fabrics such as cotton
also help avoid flare-ups.

lines and wrinkles.So always remember to nourish and moisturise your skin.

making it smoother and softer.Moreover, these vitamins counter the effects of free radicals.

skin.The oily skin is concentrated on the T-zone, which is across the foreheat, down the nose
and chin.Whenever you wash your face, you may find that some areas of your face feel tight
after washing; and that these parts look dull or feel dry and rough whereas the T-zone looks
shiny, feels oily to touch and is prone to pimples and blackheads.Combination skin needs
special attention because the dry parts of your face need to be considered, whereas the oily
parts need to be kept clean to avoid breakouts.Follow these simple tips each day and see what
a difference they make to your skin.

grime and make-up from your face.

Skin that looks oily, feels greasy to touch and is prone to blackheads and pimples is known as
oily skin.It is imperative to keep oily skin clean and to control the excess secretion of oil.On
the positive side, oily skin tends to age more gradually as compared to other skin types, as

skin break-outs.

leave permanent scars.There are a number of effective pimple creams available in the market
today.Consult a dermatologist to know which one is best suited for you..
