Most people think of rosacea as a red face. It’s true this skin condition can cause facial redness, but it can also cause many other symptoms. They range from pimples on your cheeks to thick skin on your nose. Rosacea usually appears on your face, but you can have it on your neck, scalp, ears, eyes, or chest, too.
As many as 16 million Americans have rosacea, yet many don't realize they have it. Rosacea can be treated, but step one is knowing it's there.
Acrocyanosis is blueness of the extremities (the hands and feet). Acrocyanosis is typically symmetrical. It is marked by a mottled blue or red discoloration of the skin on the fingers and wrists and the toes and ankles. Profuse sweating and coldness of the fingers and toes may also occur.
Acrocyanosis is caused by narrowing (constriction) of small arterioles (tiny arteries) toward the end of the arms and legs.
Rosacea symptoms often don’t start to appear until age 30 or later. Symptoms can come and go. As a result, many people think it’s acne or a sunburn.
The Types of Rosacea
Symptoms can be different from person to person. There are four basic types of rosacea. You can have just one type, or you can have more. Women tend to have rosacea more often than men, but men tend to have more severe symptoms.
Type 1: Facial Redness
This is the most common type of rosacea and the type most people know. Symptoms can include:
This type of rosacea is rare. Most people have another type first. Left untreated, it can cause skin thickening on the nose, making it look enlarged.
It can also cause:
Type 4: Ocular Rosacea
This type of rosacea affects the eyes. People often say it feels like having grit or sand in your eyes. If you have another type of rosacea, it’s important to watch for symptoms of ocular rosacea. If not treated, it can cause problems with vision.
