Every spring, there is a notable rise in patients visiting dermatology clinics, presenting symptoms such as sudden redness, hives, and widespread itching. This seasonal uptick in skin allergies is particularly pronounced during transitional periods, where rapid temperature changes, increased levels of fine dust, pollen, and ultraviolet radiation disrupt the skin's immune system in complex ways. Moreover, skin allergies are not merely a sign of sensitive skin but rather indicate a hypersensitive immune response that can lead to chronic conditions if not properly diagnosed and treated.

The three most common forms of skin allergies seen in patients this spring are hives, contact dermatitis, and the exacerbation of atopic dermatitis. Hives cause sudden swelling and severe itching in the skin, triggered by various factors such as pollen, food, and medications. If symptoms continue for more than six weeks, they are classified as chronic hives. Contact dermatitis results from direct exposure to specific irritants like pollen, cosmetics, and household chemical products, leading to inflammation in the affected areas. Furthermore, existing atopic dermatitis patients often experience a significant worsening of their symptoms during this pollen-heavy and dry season.

According to Professor Kim Sang-seok from Gangdong Sacred Heart Hospital, many individuals mistakenly believe that pollen allergies only manifest in nasal symptoms. However, a considerable number of patients first exhibit skin symptoms. Initial inappropriate responses, like scratching, can worsen inflammation and lead to secondary bacterial infections, making prompt action critical. The exacerbating factors of skin allergies during spring are primarily threefold: pollen release from trees like birch, oak, and cherry blossoms starting from March; fine dust accumulating on the skin and causing inflammation; and increased ultraviolet exposure from the sun, which can aggravate existing skin conditions.
