In another desperate attempt to sell the product, he started pointing out the bags under her eyes and smile lines, he said he had cream that would fix it in 15 minutes.
But Ms Robinson has no desire to get rid of those lines and told the salesman exactly what they meant to her.
"What's wrong with my eyes?" she said.
"I have a miracle baby at home and haven't slept in two years, so if I have bags I am grateful to have them, and my husband and I laugh a lot. Those are his fault. He loves
how I look ... I don't think I need your cream."
Despite his sales pitch being shut down, he didn't give up and told Ms Robinson her face would be sagging by the time she was 50, and she must act now or it would be too late to correct it.
"What's wrong again with a woman ageing?" she said.
"You know, my husband and I can't wait to grow old together, we talk about it all the time, how we'll be this funny wrinkled old couple.
"My husband is going to age too, we all are, it's kind of how life works."
Ms Robinson found herself an audience during the encounter. Other shoppers began listening in to her response to the salesman, who later offered her the product at a cheaper price.
But the woman said again she was happy with how she looked, and would be happy with her appearance when she was 50, because there was nothing wrong with a woman ageing.
"Old age is a privilege decided by many, and I don't appreciate you marketing youth instead of your products, and denigrating ageing women as a sales tactic.
"Thankyou, but I don't want or need your cream."
She then posted a picture of her "ageing" face on social media. Her post has been shared almost 40,000 times.
She said her post wasn't about natural beauty, or not wearing makeup, but was instead about how products are marketed to women who hate the way they look.
"It's hardwired into us from the cradle that our main value as a woman is beauty, and a standard of beauty that we can never actually attain. Even our supermodels get photoshopped," she said.
"Let's start a movement peeps, let's end predatory marketing practices that sell self-loathing to women from cradle to grave."
Ms Robinson finished by stating women had more to do in 2016 than spend another minute obsessing about wrinkles or thighs.
