Dry skin care starts with moisturisers, the most effective remedy for dry skin. Generally moisturisers are classified under 2 categories based on the way they provide dry skin care.
The first category includes moisturisers that provide dry skin care just by preserving the moisture within the skin e.g. Vaseline. These moisturisers are relatively inexpensive and are readily available (even at grocery shops).
The second category includes moisturisers that work by drawing moisture from the environment and supplying it to the skin. This is a very effective way of dry skin care in humid conditions. The moisturisers that provide dry skin care in this way are also called humectants. For proper dry skin care, you must use a non-greasy type of moisturiser, as far as possible. Humectants fall in this category. The ingredients of humectants include propylene glycol, urea, glycerine, hyaluronic acid etc
Dry skin care is not about just using moisturisers but also using them properly. The best dry skin care procedure is to cleanse the skin before the application of moisturiser. You can make your dry skin care even more effective by applying the moisturiser while the skin is still damp (after cleansing). Also, make sure that you use soap-free products (especially on your face, neck and arms). Exfoliation does help in dry skin care, by removing the dead skin cells. However, dont exfoliate too hard. Your dry skin care procedures/products should also take care of sun protection. Avoid too much and too direct exposure to sun (simply by using an umbrella/hat etc). Use a good sunscreen lotion before going out. A lot of moisturisers provide sun protection too, along with dry skin care.
You also have natural products for dry skin care i.e. products that provide dry skin care in a natural way (without the use of synthetic chemicals). These dry skin care products supply lipid enhancements to the skin, hence enabling moisture retention within the skin. Another, important thing for dry skin care is the temperature of water you use for shower or for washing your face Use warm water; too hot or too cold water can cause dryness too.
Dry skin care is also about being gentle with your skin. You should avoid harsh detergents and alcohol based cleansers. Also, after a face wash, do not rub your towel on your face, just pat gently to soak the water off.
On the whole, dry skin care is really simple for anyone who takes that seriously.
