Is Cotton Good for Eczema? The Pros and Cons

Atopic dermatitis (eczema) is a chronic inflammatory skin condition marked by dryness, intense itching, and recurrent rashes. The compromised skin barrier makes it hypersensitive to external factors. For those managing eczema, the material worn directly against the skin is a significant trigger. Clothing can exacerbate the condition through mechanical friction, heat retention, and poor moisture regulation. These factors can lead to increased itching and inflammation, setting off a flare-up cycle.

How Cotton Affects Eczema-Prone Skin

Cotton is frequently recommended as a baseline material for sensitive skin due to its natural, soft fibers and breathability. The material allows air to circulate well, helping prevent overheating. Additionally, 100% cotton is less likely to contain the harsh chemical residues or dyes found in some synthetic materials, which can trigger contact dermatitis.

The main challenge with cotton, however, is its high absorbency without adequate wicking properties. When an individual sweats or applies thick emollients, cotton absorbs this moisture and holds it tightly against the surface. This prolonged dampness increases the friction between the fabric and the already irritated skin. Increased friction and dampness can intensify itching, potentially leading to a severe flare-up.

This “wet cotton” effect means that while cotton is a suitable choice for everyday wear in mild cases, it is less ideal for situations involving heavy sweating or during active flare-ups. Organic cotton is often a better choice as it is grown without pesticides and processed with fewer harsh chemicals. However, even organic cotton retains the inherent moisture-retention drawback of the fiber.

Identifying Fabrics That Irritate Eczema

Certain fabrics are widely known to aggravate eczema due to their physical structure or lack of airflow. Wool, for example, is a common irritant because of the coarse, microscopically scaled structure of its fibers. These rough fibers cause mechanical irritation as they rub against the skin, stimulating nerve endings and causing itching. Even fine-grade wool can be problematic for extremely sensitive skin.

Synthetic fabrics, such as polyester and nylon, pose a different type of irritation risk. These materials are non-breathable, trapping heat and perspiration close to the skin. This creates a hot, humid microenvironment that encourages bacterial growth and can quickly lead to overheating and an eczema flare.

Chemical finishes applied to many textiles are another source of irritation. For example, “wrinkle-free” or “stain-resistant” garments often contain formaldehyde resins, which are known contact allergens. Harsh dyes can also leave residues that provoke an allergic reaction, requiring washing clothing multiple times before wearing.

Specialized and Optimal Clothing Choices

Superior clothing choices for eczema management focus on materials that actively regulate moisture and minimize friction better than standard cotton.

Silk

Silk is an excellent option because its protein-based fiber is exceptionally smooth, offering minimal friction against sensitive skin. It also possesses natural thermoregulating properties, helping to keep the skin cool and comfortable.

Advanced Cellulose Fibers

Advanced cellulose-based fibers, such as Tencel (Lyocell) and Bamboo Viscose, are highly effective alternatives. Lyocell, made from wood pulp, offers excellent moisture-wicking capabilities, pulling sweat away from the skin more efficiently than cotton. This rapid moisture transport helps prevent the damp, irritating environment that can trigger a flare-up. Bamboo viscose is soft, breathable, and highly absorbent, sharing many benefits with Lyocell.

Therapeutic Garments

For severe cases, specialized therapeutic garments may be recommended by a dermatologist. These medical-grade clothes are sometimes infused with compounds like silver to inhibit bacterial growth or are designed for use in wet-wrapping techniques to lock in moisture and provide a cooling effect.
