Sensitive Skin and Period Underwear: What to Know Before You Switch
Short answer
Many people with sensitive skin find period underwear gentler than pads, because there is no adhesive against the skin. Kiri isn't scented, its layers contain no dioxin, chlorine or rayon, and the wicking layer moves moisture off the skin. Start with one pair and short wear times to see how your skin responds.
If you already deal with sensitive skin, switching to a fabric that sits against you for a full day — rather than a pad you change every few hours — is a fair thing to think through before ordering, not after a reaction shows up.
What actually causes irritation with underwear generally
Most underwear-related skin reactions trace back to one of three things: synthetic fragrance or dye, tight elastic digging into skin, or trapped moisture and heat. Period underwear specifically removes one of the biggest irritation triggers other products introduce — adhesive. Pads rely on adhesive strips that stick directly to skin and fabric, which is a common source of contact irritation that period underwear doesn't have at all, since nothing is glued to you.
What to check in the fabric itself
Kiri's fabric blend and construction avoid the two most common irritation points directly: no bonded elastic digging into the skin at the leg openings or waistband, and the antibacterial treatment is aimed at odour-causing bacteria rather than added fragrance. If you're sensitive to synthetic fragrance specifically, that's worth checking against any product before buying — ours isn't scented.
Moisture is the other half of the equation
Trapped moisture against skin for extended periods is a real irritation risk regardless of what's causing the moisture, which is exactly what the moisture-wicking layer is built to prevent — pulling fluid away from the skin surface rather than holding it there. This matters more for sensitive skin than for skin that doesn't react easily, since the margin for irritation is smaller.
If you're trying it for the first time
The usual advice for introducing anything new to sensitive skin applies here too: start with one pair, wear it for a shorter stretch initially rather than a full heavy day, and watch how your skin responds before committing to a full rotation. Daywear's lighter, thinner construction is a reasonable first pair to test with, since it's the least fabric against skin of any option in the range.
When to hold off
If you have a diagnosed sensitivity to specific synthetic fabrics or dyes, that's worth checking against our fabric composition directly before ordering — we're glad to answer specifics through our FAQ or by getting in touch if your question isn't covered there.

Frequently asked questions
Is Kiri period underwear scented?
No. The antibacterial layer targets odour-causing bacteria rather than masking odour with fragrance.
Why can pads irritate sensitive skin?
Adhesive strips, trapped heat and moisture, and fragrance in some pads are common triggers. Period underwear has no adhesive at all.
How should I try period underwear with sensitive skin?
Start with one daywear pair, wear it for shorter stretches at first, and check your skin before building a full rotation.
