Dry skin
Dry skin is most common in your lower legs, arms, flanks (sides of the abdomen), and thighs. The symptoms most often associated with dry skin include:

Scaling
Itching
Cracks in the skin
       A dry skin problem can be uncomfortable and even maddening. Your skin might feel tight and painful; it might look dull or red or flaky. Worst of all is the itchiness -- the sort of overwhelming itchiness that makes you feel like you're infested with fleas, that keeps you awake at night, miserably raking your skin with a back scratcher.
Common causes:
Xeroderma is a very common condition. It happens more often in the winter where the cold air outside and the hot air inside creates a low relative humidity. This causes the skin to lose moisture and it may crack and peel. Bathing or hand washing too frequently, especially if one is using harsh soaps, may also contribute to xeroderma. Xeroderma can also be caused by a deficiency of vitamin A, vitamin D, systemic illness, severe sunburn, or some medication [2]. Xeroderma can also be caused by choline inhibitors. Detergents like washing powder and washing up liquid can also cause xeroderma.

Dry skin is red, cracked and painful. It can feel tight and uncomfortable. Some people are prone to dry skin; others have this problem due to a dry climate or severe weather changes. Dry skin can also be sensitive and needs to be treated with care. Natural remedies for dry skin are effective and gentle. Natural ingredients are ideal for dry sensitive skin because they do not contain preservatives or other harsh chemicals.
Homeopathic Treatment

Olive Oil
Olive oil can be used as a moisturizer for the entire body and face. Olive oil helps dry skin because it contains oleic acid. This causes the skin to become more permeable and hold in necessary moisture that is lost in cases of dry skin. Pour olive oil into a spray bottle and spritz your towel-dried body and face after taking a shower or bath. If the oil has difficulty spraying, run the bottle under warm water or hang in the shower to steam heat.

Petroleum Jelly and Vitamin E
For extremely dry areas such as the knees, elbows, hands and feet make a mixture of petroleum jelly and vitamin E oil. Petroleum jelly has been used for years to soften dry skin and has no chemicals or irritants whatsoever and vitamin E oil repairs damaged and scaly skin. Pour 1 tbsp. of vitamin E oil into a cup of petroleum jelly. Apply this moisturizer to the hands and feet and cover with white cotton gloves before bed. Rub into elbows and knees after a shower to keep skin soft and smooth.

PETROLEUM: The medicine is made from this ‘CRUDE ROCK OIL’, which has that smell and taste. This is used as a remedy when the skin looks dry, rough and cracked, with sensitivity to even the slightest scratch. Winter fissures, cracks and peeling of skin can be relieved by the dosage of petroleum.

GRAPHITES: This is a mineral which is used as a medicine, effectively useful in skin affections with severe itching due to persistent dryness. Painful cracks and fissures in the ends of fingers, cracks in nipples, mouth and between fingers and toes could be brought to normal health by administration of this homoeo remedy. It is commonly known as ‘Black Lead’, which occurs as a black grey, soft gelatinous solid. This could be used as a preventive, when the skin just appears to crack with an unhealthy look. It also helps to cure dry skin with ulcers that discharge sticky fluid.

SULPHUR: It is the sublimated elemental sulphur, which is converted and used as medicine, in most therapies and practices of medicine. Homoeo also uses this, to relieve skin troubles that look very dirty, unhealthy and extremely dry. Cracks that develop in the lips and corners of the mouth with much dryness can be relieved with this remedy.
