What skin diseases is boric acid used to treat?

Generally, boric acid can treat various skin conditions such as acute eczema, contact dermatitis, diaper dermatitis, seborrheic dermatitis, and impetigo. However, the use of this medication should be conducted under a doctor's guidance. Detailed explanations are as follows:

1. Acute Eczema

Acute eczema commonly presents as erythema, papules, and vesicles, often accompanied by intense itching. Boric acid solution has anti-inflammatory, anti-edematous, and astringent effects. By applying wet compresses, it can reduce exudation, alleviate local inflammation, decrease swelling, and improve the rash.

2. Contact Dermatitis

Contact dermatitis is an inflammatory reaction occurring at the site of skin contact with external substances. Boric acid can reduce inflammation-induced redness and swelling. Its anti-inflammatory properties help soothe skin inflammation caused by contact allergies and inhibit the release of inflammatory mediators.

3. Diaper Dermatitis

In infants, the diaper area is frequently exposed to urine and feces, leading to prolonged dampness, which makes the skin prone to diaper dermatitis. Boric acid has cleansing and astringent properties, helping to keep the diaper area dry and reducing bacterial proliferation.

4. Seborrheic Dermatitis

Seborrheic dermatitis typically affects areas rich in sebaceous glands, such as the face and scalp, and is characterized by erythema and greasy scales. The astringent effect of boric acid helps reduce skin oil secretion and alleviate symptoms of seborrheic dermatitis.

5. Impetigo

Impetigo is a common pyoderma characterized by pustules and honey-colored crusts. Boric acid can clean the skin surface, reduce bacterial growth, and suppress local inflammation. In the early stages of impetigo, it helps prevent the spread of infection and promotes crusting of the pustules.

Boric acid should be stored out of children's reach in a cool, dry environment. It should not be stored together with alkaline substances to avoid chemical reactions.
