No — that's a popular myth; the real practice was Greek and medicinal
There's no ancient evidence Romans bottled gladiator sweat for romance or skincare. What was real is gloios: Greek gymnasium attendants scraped the sweat, oil, and grime off athletes with a curved blade (a strigil) and sold it — but as a medicine for swelling and inflammation, not a cosmetic. Pliny the Elder recorded the practice with open disgust.
