If your skin reacts to underwear, with redness, itching, or simply discomfort, you are not alone. Many people have sensitive skin and suffer from poor quality underwear. But here's the good news: there is definitely underwear that feels good and doesn't irritate your skin.
Why does skin react sensitively to underwear?
Your skin doesn't just react to underwear for no reason. There are concrete reasons:
- Chemicals in the fabric. Conventional underwear often contains pesticides, dyes, and bleaches. These can trigger allergies, especially in delicate areas like the genital area or under the breasts.
- The surface structure. Rough fabrics cause friction and lead to irritation, especially when worn all day. Lyocell, with its smoother surface, causes significantly less friction.
- Sweat and moisture. Poor moisture regulation creates a humid climate under clothing. This promotes fungi and irritation. The genital area is particularly susceptible.
- Synthetic fibers. Polyester and co. don't let your skin breathe. The climate under the underwear becomes damp and warm, not ideal for sensitive skin.
- Seams and workmanship. Thick, raised seams can rub. Labels that feel like sandpaper also contribute to skin irritation.
The combination makes it: Sensitive skin often reacts not to a single factor, but to the sum of several. Therefore, it is not enough to choose a better material; the workmanship must also be right.
The best materials for sensitive skin
Not all materials are created equal. Here's our overview, from best to most problematic:
Lyocell (TENCEL)
Honestly: Lyocell is the best choice for truly sensitive skin. It is produced in a closed loop, which means fewer chemicals in the material.
- Feel: Silky smooth, minimal friction
- Moisture: Temperature regulating, absorbs and releases
- Skin compatibility: Excellent, hardly any chemical residues
- Price: Higher, but a worthwhile price for skin comfort
Organic Cotton (kbA)
Certified-organic cotton (kbA) is also a very good choice, as long as the quality is right. Air-permeable and robust. Gets softer with every wash.
- Feel: Soft, classically comfortable
- Moisture: Air-permeable, absorbs moisture
- Durability: Very robust, long-lasting
- Price: Moderate, good value for money
Modal
Modal is similar to Lyocell and also a good option. It is soft, gentle on the skin, and relatively sustainably produced. It is slightly cheaper than Lyocell, but still not inexpensive.
Elastane and synthetics
Elastane makes underwear elastic, but it is made of polyurethane, a petroleum-based synthetic that can be irritating to sensitive skin. The same applies to pure polyester. If elastane is used, it should only be a small percentage (5-10%), not 30%+.
Underwear for allergy-prone skin and eczema
With eczema, contact allergies, or generally sensitive, irritation-prone skin, every detail of the fabric matters. Underwear sits directly on the skin, often for hours, so the choice of material and construction can make a noticeable difference in everyday comfort.
What matters for allergy-prone skin
- Smooth fiber surface. The smoother the individual fiber, the less friction on the skin. Lyocell and Modal have a noticeably smoother surface than coarsely spun cotton or synthetics, which can feel more comfortable on irritated skin. You can read how the fiber is made in our Lyocell guide.
- Flat seams. Raised, thickly stitched edges rub with every movement. Flat, smooth seams noticeably reduce this friction point, especially at the waistband and leg openings.
- No scratchy labels. Sewn-in, rough label edges are one of the most common triggers for localized itching. Soft, printed-on, or absent labels are the gentler choice.
- Breathability. A fabric that absorbs and releases moisture keeps the climate against the skin more balanced. A constantly damp, warm environment can encourage further irritation, especially when the skin barrier is already compromised.
- Tested supply chain. An Oeko-Tex Standard 100 tested supply chain means textiles are tested for a broad range of harmful substances, an additional point of orientation when buying.
If you prefer natural fibers with a classic feel, our organic cotton bottoms made from kbA cotton are a gentle alternative to Lyocell.
Important: these material properties can support a more comfortable, low-irritation feel day to day, but they don't replace medical treatment. If you have diagnosed eczema, persistent itching, or changes in your skin, a dermatologist is the right point of contact.
What to look for when buying
Good material alone is not enough. Here are five things you should check when buying:
- Check fabric composition. The label tells you what your underwear is made of. Pay attention to:
- At least 90% natural fibers (organic cotton, Lyocell, Modal)
- Maximum 10% elastane for elasticity
- No polyester or other synthetics
- Flat seams and good workmanship. Feel the underwear. The seams should be flat and smooth, not raised. The label should either be hidden inside or very soft. No rough edges or loose threads.
- Color and finish. White or natural-colored underwear is often less chemically burdened than dyed. It's a good sign if the brand avoids optical brighteners.
- Size and fit. Too tight underwear chafes, too loose it slips. Both cause discomfort and can irritate the skin. The right size is therefore important, also for sensitive skin.
- Try it out. The best way to find underwear for sensitive skin is to try it on. Every body is different. What fits perfectly for your friend might irritate you. That's okay, try different materials and brands.
Certifications that provide security
These certifications are particularly important if you have sensitive skin:
- OEKO-TEX Standard 100. The most important seal for your skin. The finished product is independently tested for harmful substances. If you only pay attention to one thing: look for OEKO-TEX.
- Certified organic farming (kbA). Controlled organic cultivation means the cotton is grown without synthetic pesticides. Combined with low-residue processing, this keeps the fibre gentle on sensitive skin.
- Tested for allergens. Some brands have their underwear tested for allergenicity. This is even more specific than OEKO-TEX and particularly helpful for severe allergies.
Tip: OEKO-TEX Standard 100 gives reliable safety for sensitive skin.

Frequently Asked Questions
What underwear is good for allergy-prone skin?
For allergy-prone skin, underwear made from the purest possible natural fiber with a smooth surface works best, such as Lyocell or high-quality organic cotton. Flat seams, a soft or absent label, and an Oeko-Tex Standard 100 tested supply chain matter too. If you have known contact allergies to specific fibers or additives, talking to a dermatologist can help narrow down which materials you tolerate best.
What material is best for eczema?
With eczema, many people find smooth, air-permeable natural fibers like Lyocell or soft organic cotton more comfortable, since these materials create less friction and regulate moisture well. Scratchy seams, rough labels, and a high synthetic content can make wear less comfortable. Since eczema is an individual skin condition, this guidance doesn't replace a conversation with your dermatologist.
What can I do about itchy skin caused by underwear?
If underwear itches, start by looking at the material, fit, and label. A high proportion of polyester or elastane, rough seams, or a too-tight fit can be the cause. Switching to smoother natural fibers with flat seams and a soft label can noticeably improve comfort. If the itching persists or your skin changes, it should be checked by a doctor.
Is Lyocell or organic cotton better for sensitive skin?
Both materials are considered well tolerated for sensitive skin, with slightly different properties. Lyocell has a particularly smooth, silky surface and regulates moisture very well, which often makes it the first choice for higher sensitivity. Organic cotton is soft, air-permeable, and durable, a proven alternative with a classic feel. Which material feels better often comes down to personal preference.
How do I recognise underwear for sensitive skin when shopping?
Underwear for sensitive skin can be recognised by a high natural fiber content (Lyocell, Modal, or organic cotton), flat seams, a soft or absent label, and an Oeko-Tex Standard 100 tested supply chain. Fit matters too: underwear that's too tight or too loose can rub or slip, even in the best material.
