What are the symptoms of an allergy to water or milk?

Symptoms of lotion or emulsion allergy usually manifest as various skin and possibly respiratory discomforts. Specifically, skin reactions may include redness, itching, blisters, hives, and in severe cases, purpuric pruritus or allergic dermatitis. These skin symptoms typically appear shortly after using the lotion or emulsion and commonly occur at contact sites such as the face, neck, and arms. Additionally, lotion or emulsion allergy may also cause respiratory symptoms such as wheezing, nasal congestion, and runny nose. In severe cases, it may even trigger asthma, presenting as difficulty breathing and shortness of breath. If the above symptoms occur, discontinue use of the allergenic lotion or emulsion product immediately and seek medical attention as soon as possible. Under a doctor's guidance, antiallergic medications such as antihistamines can be used for treatment. After recovery, it is recommended to choose suitable hypoallergenic moisturizing products and perform a skin test before use to avoid future allergic reactions.
