Eczema, Salicylic Acid, and Skin Care Considerations in Canada

Eczema, also called atopic dermatitis, commonly begins during childhood and can continue into adulthood. Many Canadians experience intermittent flare-ups throughout their lives. While not considered medically serious for most people, eczema can be uncomfortable, itchy, and disruptive — and cracked or open skin may become prone to infection.

Among the skincare tools sometimes used to support symptom management is salicylic acid, a topical agent that helps soften and loosen dry, flaky skin so other treatments can work more effectively.

What is Salicylic Acid?

Salicylic acid is used in dermatology to help break down thick or scaly skin. It is available in a variety of topical forms, such as:

• Creams and gels

• Ointments

• Lotions and topical solutions

• Pads or plasters

• Shampoos

Products may vary in strength depending on purpose, ranging from low concentrations for facial care to higher percentages for thicker buildup on elbows, knees, or scalp.

How It Fits into Eczema Care

For some Canadians with eczema, salicylic acid may:

• Help soften keratin within the skin structure

• Remove dry or flaky surface layers

• Improve absorption of moisturizers and prescribed creams

Eczema tends to appear on the arms, behind the knees, and on the face or neck — but it can affect nearly any body area. It often presents as itchy, red, scaly patches that may ooze slightly before crusting over. Symptoms can worsen at night or during flare triggers.

Eczema Triggers and Flare-Ups

Flare-ups can come and go and may be influenced by factors such as:

• Dry Canadian winters and low humidity

• Hot baths or showers

• Sweating

• Allergies or environmental irritants

• Stress

• Cigarette smoke

Building a daily skin routine and recognizing personal triggers can help reduce flare intensity.

Possible Side Effects of Salicylic Acid

Mild side effects may include temporary irritation — especially on sensitive or damaged skin. Less commonly, stronger reactions such as flushing, warmth, or discomfort may occur.

While absorption through the skin is usually minimal, medical guidance is recommended for:

• Young children (salicylic acid is generally avoided under age 2)

• Pregnancy or breastfeeding

• Large treatment areas or high concentrations

A healthcare provider may recommend alternatives if eczema is widespread, infected, or severe.

Managing Eczema Beyond Topicals

Depending on severity, eczema may be supported through a combination of:

• Unscented moisturizers

• Humidifiers (helpful in dry winter climates)

• Calamine lotion or cool showers

• Allergen or dust control

• Gentle soaps and detergents

For more troublesome cases, physicians may consider medications such as:

• Topical corticosteroids

• Antibiotics (if secondary infection is suspected)

• Antihistamines for itch

• Immunomodulators

Allergy control may not eliminate eczema entirely, but it can reduce flare frequency.
