Rosacea is a chronic skin condition that causes redness, flushing, and visible blood vessels on the face. It can also cause acne-like bumps and pimples, and in some cases, the nose may become swollen and bumpy from excess tissue. The exact cause of rosacea is not known, but it is thought to be related to a combination of genetic and environmental factors.
Treatment options for rosacea include:

Topical medications: Topical medications, such as metronidazole, azelaic acid, and ivermectin, can help to reduce redness, inflammation, and acne-like bumps.

Oral medications: Oral antibiotics, such as doxycycline and minocycline, can be used to reduce inflammation and clear up acne-like bumps.

Laser and light therapies: Laser and light therapies, such as intense pulsed light (IPL) and laser resurfacing, can be used to reduce redness and visible blood vessels.

Lifestyle changes: Avoiding triggers such as sun exposure, spicy foods, alcohol, hot drinks, and stress can be helpful in managing the symptoms of rosacea.

Skincare: A gentle skincare routine that includes mild, fragrance-free products, moisturizers, and sun protection can help to soothe the skin and reduce the risk of flare-ups.
