LaMelo Ball's game is smooth on the court, and he might be trying to get your skin to feel the same -- the NBA star's team just filed a trademark for his very own skincare line.
TMZ Sports has learned ... LaMelo's manager, Jermaine Jackson, filed papers last week to trademark the phrase "LaFrance Skin By LaMelo Ball" for the purpose of "Skin care products, namely, non-medicated skin serum."
The filing was made under the name "Purple Goat Management" ... which is a nod to the nickname JJ gave himself.
