Skincare did not stay in the bathroom. It moved into the underwear drawer.
A new category called “carewear” is turning basics into beauty products. UK label Underdays launched pre- and probiotic-infused briefs designed to support the skin’s microbiome. A French label followed with an athleisure line blending beauty ingredients directly into the fabric. The global underwear market is projected to grow from roughly $101 billion to $137 billion by 2034, and ingredient-infused fabric is a real part of that curve, not a gimmick.
But here is the tension: the business model is still being figured out, and brands are making biome and skin-benefit claims before the long-term data fully exists. The brands that last will be the ones who can substantiate what they market, not just the ones who move first.
And moving first takes capital. Fabric science, safety testing, and credible health claims are expensive and slow, which means innovation in categories like this tends to favor founders who already have funding, not just a good idea.
That is the same gap that shows up across every category in fashion right now: smart eyewear, wellness-integrated apparel, biotech textiles. The founders who get resourced early are the ones who define what the category becomes.
Fashion Equity Firm helps founders build the positioning and financial literacy to compete for capital and shelf space while a category is still being defined, not after it is already crowded.
