Rosacea is a chronic, recurring condition in which flushing symptoms may recur and make it difficult to return to normal. Patients can usually get basic control or significant improvement of symptoms after 3 months of regular treatment, but most patients have recurrent episodes over years or decades and require repeated intermittent treatment. If the symptoms of rosacea are mild and the patient actively follows the doctor’s instructions and adopts standardized treatment methods, the symptoms will be relieved more quickly, and the inflammation may gradually subside and the facial flushing will improve in about 3 months. However, some patients with severe symptoms and impaired skin barrier function usually need at least 3 months to control the disease. The disease is a chronic, recurrent disorder characterized by paroxysmal flushing and persistent erythema of the face. Although the flushing improves significantly after standardized treatment, the condition may recur if the patient is exposed to heat, spicy and irritating foods, or is emotionally stressed, making the condition long-lasting and the flushing difficult to return to normal. It is recommended that patients with rosacea go to a regular hospital in time and use medication and phototherapy to improve the condition under the guidance of a doctor. At the same time, patients should do a good job of skin care, pay attention to sun protection, to protect the skin barrier function, light diet, avoid spicy and irritating food.
