Which skin condition is often aggravated by dry skin and irritation?

Dermatitis is indeed the correct answer because this skin condition is characterized by inflammation that can be triggered or worsened by factors such as dry skin and irritation. When the skin's barrier function is compromised, it becomes more susceptible to irritants and allergens, which can lead to flare-ups. Symptoms of dermatitis often include redness, itching, and a rash, which can be intensified in dry conditions.

Psoriasis, while it can also be affected by dryness, primarily involves an autoimmune response that causes rapid skin cell turnover, leading to thick, scaly patches rather than the irritant-induced inflammation seen in dermatitis. Oily skin is not a skin condition aggravated by dryness; rather, it is a different concern where excess oil can lead to other skin issues like acne. Acne, which is primarily caused by clogged pores and bacteria, may not directly relate to dry skin and irritation in the same way as dermatitis does. Thus, dermatitis is the most relevant condition associated with dry skin aggravation.
