Which condition is characterized by flushing, erythema, and telangiectasia on the face?

The condition characterized by flushing, erythema, and telangiectasia on the face is rosacea. This chronic skin condition primarily affects the facial skin and leads to redness and visible blood vessels. It often starts with intermittent flushing and can progress to persistent redness, along with the appearance of small, red, pus-filled bumps. This combination of symptoms distinguishes rosacea from other skin conditions.

In contrast, while aging skin changes can cause some degree of erythema due to thinning and loss of elasticity, they do not typically involve the flushing and telangiectasia seen in rosacea. Psoriasis primarily presents as thick, scaly plaques on various parts of the body, rather than the flushing or erythema seen on a deeply vascularized area like the face. Contact dermatitis is an inflammatory reaction to a substance and may involve redness and irritation, but it is often associated with itching and does not usually present with the telangiectasia that is characteristic of rosacea.

Thus, rosacea is the most fitting answer due to its specific symptoms of flushing, persistent facial redness, and visible small blood vessels.
