Looking at her, you would never guess that Joan Woodhouse was 92 years old.
It turns out that Joan has been using the same skincare product on her face since she was 16 years old, and you can pick it up for as little as £2. Watch here:
In one video, which has gathered an impressive 91,000 likes and 1.6 million views, Joan's granddaughter helped her to spread the word.
"Grandma, no one believes you're 92. Can you tell us a bit about yourself," she asked her nan.
"You look so good for your age and everyone wants to know what skincare you use."
Joan, started by revealing that she was born on 6 September 1930 - though we're still struggling to believe it ourselves.
The grandmother continued that, when she was just 16 years old, the first Nivea cream had hit shelves.
She said: "My friend came to the house and she said, ‘This cream has just come out, Joan. Try it, it’s brilliant.'
"So I’ve used Nivea cream for years and years and years."
The classic Nivea cream that comes in a small, deep blue tin is all Joan has used to achieve her youthful looks.
On Nivea's website, you can pick up a 50ml tin of the cream for just £2.49. What a steal.
After Joan spilled her beauty secrets, viewers were shocked and vowed to pick up their own tin of Nivea ASAP.
"I seriously thought she was in her 60s... she is beautiful," commented one follower.
"This has got to be a joke she looks so good," raved a second.
"I am buying a ton of Nivea today!!! You look fantastic," added a third.
"Wow you look amazing! Nivea are going to use you as their poster girl!" wrote a fourth.
And Nivea plan to do just that.
After Joan's video went viral on TikTok, her granddaughter shared a some exciting news in the comment section.
She wrote: "Message from Grandma Joan - Because of you guys and the lovely messages - NIVEA have asked to collaborate with me. I'm overwhelmed. Thank you!"
When one cynical viewer asked if Joan had ever had any cosmetic surgery, Joan posted a new video to set the record straight.
"No surgery at all on my face... Well I've had hips and knee surgery," she admitted.
"I couldn't afford it! I've had eight children, eighteen grandchildren, ten great-grandchildren - I've never had enough money to do that!
"When you see people that have got botox, you can tell. They seem to freeze, they don't seem to be able to smile properly anymore. It just doesn't look normal at all.
"Goodness knows what they're going to look like at my age!"
