Atopy (allergic constitution)

An allergic constitution refers to the body producing an excessive amount of a specific antibody: immunoglobulin E (IgE). When exposed to allergens, the immune system overreacts, leading to an allergic reaction. Allergic constitution may manifest as eczema, and may also be accompanied by other symptoms such as asthma, hay fever, and conjunctivitis.

Eczema

Eczema is a non-contagious skin condition that is usually accompanied by intense itching. There are several types of eczema, including contact eczema and atopic eczema. Eczema alternates between remission and flare-ups and may begin as early as a few months after a baby's birth.

Emollient

Moisturizers are products that soften the skin and soothe inflammation. They are recommended for use during remission of atopic dermatitis to nourish the skin, and can also be used in conjunction with a prescription medication (such as steroid creams) during flare-ups to relieve symptoms. Some moisturizers can immediately reduce itching by up to 95%. When choosing a moisturizer, please pay attention to: whether it is specifically formulated for infants and young children, whether it uses natural or patented ingredients, whether it is highly tolerable, hypoallergenic, and preservative-free. These are all important indicators for ensuring your child's skin health.

Allergens

Allergens are substances that trigger allergic reactions in some people upon contact. They are commonly found in the environment (such as pollen, dust mites, and pet dander) or in food.

Dermo-corticoid ointment

Steroid creams are topical medications containing steroids used to treat specific symptoms of skin inflammation.

Flare-up

This refers to the acute flare-up stage when a rash or eczema suddenly appears on the skin.

Itching (Pruritus)

Itchy skin can range from mild to severe. Some skincare products can reduce itching by up to 95% immediately.

Dermatitis

Dermatitis refers to an inflammatory condition of the skin; therefore, atopic dermatitis is also called atopic skin disease. Dermatosis, on the other hand, refers to all skin diseases. Atopic dermatitis falls under both the category of dermatosis and dermatitis.
