1. What is red caviar?

Rosacea is a chronic disease, caused by a disorder of the sebaceous hair follicle units in the skin. The disease is more common on the face than on other areas of the body. The disease appears with symptoms such as: redness, stinging, burning, pustules, etc. Therefore, rosacea is often mistaken for acne and other allergic diseases.

Red caviar is not uncommon but relatively common among the population. The onset of skin symptoms usually occurs after the age of 30. However, it can also occur in children, adolescents or young adults. Rosacea is more common in women than in men and less common in dark-skinned people.

2. What causes rosacea?

Although we know that rosacea is a chronic disorder of the sebaceous follicular units. However, the true cause of the disease has not been elucidated yet. There are many theories about the cause of the disease, such as:

• Environment

The theory is that the skin is initially damaged by direct exposure to ultraviolet rays from the sun over a long period of time. Then cause dysfunction of blood vessels in the facial skin. Symptoms and signs are red skin, dilated blood vessels spreading throughout the face.

• Food

There are no studies that clearly prove that foods can cause rosacea. However, it has been observed that the disease will be aggravated by drinking alcohol, hot beverages or eating spicy foods.

• Medicine

Using corticosteroids or blood pressure medications that have the side effect of dilating blood vessels can make the condition worse.

In addition, using topical creams and cosmetics of unknown origin to dilate blood vessels in the facial skin also make rosacea flare up severely.

• Genetics, race

We will be at risk of disease when there is a close family member with Rosacea . Rosacea can happen to anyone but is more common in white or light-skinned people and less common in black or dark-skinned people.

3. Symptoms of rosacea?

Red caviar manifests itself through the following symptoms:

• Position

The symptoms of rosacea usually appear only on the facial skin and are concentrated in the middle of the face such as the forehead, nose, cheeks, and chin.

The disease can also affect the eyelids, and rarely occurs in other areas of the body.

• Red and dry skin

The first common symptom of rosacea is flushing.

In the red area, many small blood vessels are visible on the surface of the skin and the skin becomes dry.

• Stinging, burning

This symptom is often accompanied by facial redness. The patient feels the skin is red, stinging, burning or itchy. Appears more when using skin care products or makeup. It is this point that makes patients think they are allergic to skin care cosmetics.

• Red acne, pustules

In addition to red skin symptoms, the patient may have many red pimples or pustules on the face.

The appearance of these pimples can be misdiagnosed with acne, but in the case of rosacea there will be no blackheads or hidden comedones as in acne.

• Eye irritation

In some cases, Rosacea affects the eyes with dilated blood vessels and is evident on the whites of the eyes, causing the eyes to become red.

Patients often feel dry eyes, itchy eyes, watery eyes, swollen eyelids and photophobia.

In severe cases, if left untreated, the person can experience reduced vision or even blindness.

• Progress

As the disease progresses, the skin in the affected area will thicken, leading to deformation of the nose, forehead, chin or eyelids.
