The art of seduction has new war paint.

Heaux Cosmetics is a new line of “sex-proof” makeup — gels, powders and pastes — designed specifically for sex workers.

“A lot of makeups claim they’re long-wearing, and you might be able to get through a cocktail with them, but not a b - - w job or a hot shower,” the 29-year-old creator Lydia Dupra — an escort-turned-guidance counselor for professional temptresses who calls herself the “Heaux Mentor”— tells The Post.

“When someone books an overnight appointment with you, they expect you to still be hot in the morning, as unrealistic as that is. So having makeup that is still on when you wake up is massive,” says Dupra, who went viral last year when she posted a video confessing that she was being haunted by her deceased 300-pound sugar daddy, Brad. “It’s game changing.“

The collection of roughly 25 products includes lipstick, eyeliner and eye shadow with cheeky names such as “In the Will,” “Offshore Account” and “Dubai,” and they’re made to be smear-resistant. Dupra, who shares her experience working as an escort for the rich and powerful in her books “The Complete Guide to Escorting” and “My Heaux Memoir,” says that the power of her cosmetics doesn’t just impact the ladies.

Makeup can make or break an affair for the Johns, as well.

“If you leave lipstick on the collar of a client it could potentially ruin his entire life if he is married, or it could be a sex scandal,” she says. “Or, if it’s just a really nice shirt, he could be like, ‘You bitch, I’ll never hire you again. This is Versace!’ ”

Dupra knows the cost personally. She once lost out on a fortune when a randy billionaire showed her the door because of her perfume.

“He was absolutely beyond wealthy and allergic to perfume,” she says. “I forgot, and when I met him he started wheezing, sneezing and coughing. He never called me again. When you are that intimate, you can’t take chances like that with health and allergies.”

For that reason, her products don’t have a fragrance. But she does have two subtly-scented “secret weapons,” infused with Oxytocin (the so-called “love hormone”) and pheromones to relax clients and turn on those around them. She’s also got a proprietary anal-bleach serum ($60).

Dupra says that she has been obsessively researching the beauty industry for years to create her long-wear, E.U.-certified products, which range in price from $18 to $80.

“There is a difference between, ‘Oh, this lasts a long time!’ and ‘Oh, my God, it won’t come off,’ ” she says. “I told the laboratory, ‘No, I literally don’t want it to come off.” (She suggests an oil-based makeup remover and “being patient” if you do indeed want to wash it off.)

“I personally tested these products for months,” she says. “I have sex in them. I sleep in them. I have a hot shower in them. I wear them in a good mood and in a bad mood, and I cry in them.”

Dupra has already received nearly a thousand online orders, and she hopes to open a Los Angeles store in the next year. But her real ambition is to “create a social movement.”

“I want there to be more businesses run by sex workers for sex workers so we keep the money in the community,” she says. “But my audience is way larger than sex workers. I’ve worked with everyday women who want to feel sexy again. They say, ‘Oh, my God, I put it on and my husband loved it. I felt like a high-class escort.’ And I’m like, ‘Yeah, it feels damn good to be an escort.‘ ”
