Merino wool and sensitive skin: what dermatologists say

Laine mérinos et peaux sensibles : ce que disent les dermatologues

From the very first hours of life, a baby's skin reveals its fragility. Thin, permeable, and still developing, it becomes the first sensitive link between the baby and the world. Every touch, every fabric, every caress is felt intensely. This still-immature dermis absorbs emotions as much as it does physical discomfort. It demands protection, gentleness, and infinite care.

Choosing baby clothes then becomes a very personal decision. However, not all fabrics are created equal: some irritate, others soothe. This is where merino wool truly shines. Exceptionally fine, it is soft to the touch and renowned for its natural properties that are gentle on even the most sensitive skin.

Understanding the sensitive skin of infants

In infants, the epidermis is about five times thinner than that of an adult. The skin barrier is imperfectly formed, making the skin more permeable to allergens, moisture, and microorganisms. It dries out more quickly, is easily irritated, and reacts to the slightest stress.

An unstable pH, a developing skin flora, and low sebum production explain why many infants experience redness, dryness, or even atopic eczema. In this context, textiles become a key player in skin health.

What makes merino wool so different?

An exceptionally fine fiber

While conventional wool can reach 30 microns, merino wool often falls below 18 microns, finer than half the thickness of a human hair. It bends upon contact with the skin without causing irritation.

A living, breathable fiber

Unlike synthetic fibers, merino wool is biodegradable and reacts to variations in temperature and humidity. It helps the body maintain its thermal balance.

A naturally hypoallergenic fiber

Naturally antibacterial thanks to keratin, it regulates moisture and prevents maceration, limiting itching and irritation.

Merino wool: a refuge for sensitive skin

Several dermatological studies have shown that babies with atopic dermatitis had fewer symptoms when wearing fine merino wool, compared to cotton.
