Acne Vulgaris
Acne Vulgaris ( 39 Questions)
Presence of comedones - The presence of comedones is common in both acne vulgaris and acne rosacea, and it does not help differentiate between the two conditions.
Age of the patient - While age can provide some clues, it is not a definitive diagnostic criterion as both acne vulgaris and acne rosacea can affect individuals of different age groups.
The distribution of the lesions is a key diagnostic criterion used to differentiate acne vulgaris from acne rosacea. Acne vulgaris commonly affects the face, neck, chest, and back, while acne rosacea typically presents with erythema (redness) and affects the central areas of the face, such as the cheeks and nose.
Severity of skin redness - The severity of skin redness is a characteristic of acne rosacea, but it alone does not differentiate it from acne vulgaris. The distribution of lesions is more specific for distinguishing between the two conditions.
