Dry skin is a very common problem which occurs when the top layer of the skin lacks moisture and/or sebum.It is also called as Xerosis. A more sever condition of dryness is an inherited group of disorder called as Icthyosis. Dry skin can be a temporary and seasonal problem. Often cold winters cause dry skin due to the low humidity level,sites affected are especially exposed areas like your extremities. But for some people, it can be a life-long problem making it a serious healthcare concern; more so if you are elderly and susceptible to dry skin.

- Shrunken, wrinkled and dehydrated looking skin.
- Tight feeling skin especially after your bath/swim/shower.

- Hands.

Seeking medical care
When dry skin is seasonal and not very severe, high-quality emollients and moisturizers will help. But you must see your dermatologist when

- The skin looks red and dry.
- Itching is persistent, severe and interferes with your sleep.
- Skin is split and cracked.
- Skin has open and raw areas from scratching that may get infected.
Diagnosis
A detailed history is taken regarding the onset and nature of the disease.A history regarding any concomitant medical condition like for eg thyroid/diabetes or any other relevant medical history.A detailed drug history because certain anti-hypertensive and anti-hyperlipedimia and many more can cause drug induced dryness.Finally a family history is also significant.Your doctor will do a physical examination to check out the severity of the condition. He will order blood and urinalysis.A skin biopsy is never needed but if its a severe and inherited condition then one may be done.
He will ask all details like
- When was the onset?
- What makes the condition worse?
