How Is Rosacea Diagnosed?
Rosacea can look likeacne,the butterfly facial erythema of lupus, or allergies.
Generally, the person’s medical and symptom history and triggers can help differentiate these skin reactions.
Skin care is important too.
Avoiding heat and sweat can help prevent flare-ups too.
Prescription treatments include oral medications and topical products to apply directly to your skin or eyes.
Laser treatment procedures can reduce some of the cosmetic effects of rosacea.
Although rosacea doesn’t ever go away, you might ease flare-ups and manage symptoms.
Living with rosacea can present some emotional challenges.
Skin flare-ups can worsen when you are under stress or in response to other emotions such as depression.
If your skin condition is taking a toll on your well-being, discuss your feelings with your healthcare provider.
You may also benefit from counseling or mindfulness training.
As such, therapy is an ongoing process and works best with consistent use of treatments and trigger avoidance.
Symptoms include flushing, sensitive skin, papules, pustules, and eye irritation.
The causes of rosacea are thought to be genetic and environmental.
