Ichthyosis vulgaris is characterized by Dry skin with small scales in a color range from white to dirty gray or brown.
Ichthyosis vulgaris slows your skin's natural shedding process. This causes chronic, excessive buildup of the protein in the upper layer of the skin (keratin). Symptoms include:
- Dry, scaly skin
- Tile-like, small scales
- White, gray or brown scales, depending on skin color
- Flaky scalp
- Deep, painful cracks in your skin
The scales usually appear on your elbows and lower legs and may be especially thick and dark over your shins. Most cases of ichthyosis vulgaris are mild, but some can be severe. The severity of symptoms may vary widely among family members who have the condition.
Symptoms usually worsen or are more pronounced in cold, dry environments and tend to improve or even resolve in warm, humid environments.
