uneven surface, which appears on the nose, cheeks, eyebrows, chin, nose tip and alar. This disease is more common in middle-aged people, among whom there are more male patients, and the condition is also heavier.
At present, it is believed that rosacea is mainly related to follicle mite infection. In addition, a recent study by the American National Acne Society shows that the main inducing factors of rosacea include: sun exposure, emotional tension, hot weather, wind blowing, physical exercise, alcohol, hot water bath, cold weather, spicy food, humidity, indoor sultry, skin care products and hot drinks.
Dietary problems that patients with rosacea should pay attention to
First of all, we should know that rosacea is incurable, but it can be controlled through treatment. The key point in the treatment is to try to avoid the symptoms that induce rosacea. At ordinary times, it is also very helpful for patients to improve their diet and daily life. The main aspects include the following:
*
Diet is light, eating more fruits and vegetables, fasting irritating food and drinks, and correcting constipation.
*
You should minimize the sun exposure, wear a hat with a wide brim, and use a sunscreen with a sun protection factor of at least 15.
*
Contact with irritating substances should be avoided, and soap-free cleaners should be used, and astringents and abrasives should be avoided.
*
You should keep a diary of rosacea inducers for 2 weeks in a row, and write down the reasons that may promote the onset or aggravation of the disease, so as to determine and avoid contact with these inducers in the future.
local treatment of rosacea
patients with mild rosacea can be controlled by local drugs alone. For slightly complicated cases, oral and local drugs can be used at the beginning. After the condition is relieved, patients can often stop taking oral drugs and use local drugs alone. Re-use oral drugs in the case of occasional attacks.
metronidazole
metronidazole is the most commonly studied topical drug for the treatment of rosacea. At present, there are ointments, gelling agents and lotions to choose from.
nitrohydroxyethyl oxazole is an isopyrazole with antibacterial effect. The exact mechanism by which the drug can improve the symptoms of rosacea is unclear, which may be related to its anti-inflammatory and immunosuppressive functions. It is also effective in the treatment of papules and pustules, and can reduce chafing erythema. However, it usually has no effect on capillary dilation. The use of metronidazole is easily accepted by patients because it is convenient to use and has mild side effects. Only more than 2% patients reported tingling, dryness, itching and burning after use.
sodium sulfacetamide
sodium sulfacetamide is also used for local treatment of rosacea. However, such drugs should be avoided in patients who are allergic to sulfonamides. At present, there are several different types of sulfacetamide sodium lotions.
clindamycin (clindamycin, clindamycin)
Although the local clindamycin preparation has not been approved by the Food and Drug Administration for the treatment of rosacea, its water gel and lotion are effective in the treatment of rosacea and are easily tolerated by patients.
azalea acid (azelaic acid)
The well-known azalea acid used to treat acne vulgaris (commonly known as "acne", "acne" and "wine thorn") can also be used to treat rosacea. In a randomized comparative study among patients with papular pustular rosacea, scientists compared the efficacy of 2% topical ointment of rhododendron and .75% nitrohydroxyethylazole ointment. After 15 weeks of treatment, the two drugs have achieved the same effect, and both of them have significantly reduced the papules and pustules on the patient's face.
systemic treatment of rosacea
severe rosacea needs systemic treatment. Systemic treatment usually begins with oral antibiotics, such as tetracycline (25-5mg, twice daily), doxycycline (5-1mg, twice daily), or minocycline (5-1mg, twice daily).
