90-year-old woman who 'doesn't look at a day over 50' says she only uses one product on her skin

In a viral clip, a 90-year-old grandmother revealed her simple skin care secrets, highlighting how less is more when it comes to skin care.

The video, shared by her granddaughter Sarah Grande, left viewers astonished by the senior woman's youthful appearance, with one noting that "she doesn't look a day over 50, she looks amazing".

The clip shows the granddaughter quiz the 90-year-old about her beauty secrets, inviting her to reveal a super simple regimen.

"The only thing I use is Purpose by Johnson and Johnson, it's a moisturiser," the 90-year-old stated in the clip.

"I imagine purpose moisturiser will be flying off the shelves now," noted one social media user, while another chimed in: "She looks younger than me and I'm in my 40s."

When asked about her history of sun exposure, the grandmother admitted her past love for sitting in the sun.

She noted that she exclusively used SPF when she would sit in the sun, but rarely has the chance to anymore.

In a separate video, she also disclosed occasionally using olive oil on her face. She confessed that she still follows the practice "once in a while".

Viewers shared that olive oil has done wonders for keeping their skin intact as they enter their 60s.

One viewer wrote in the comments: "I've had people who work in the industry make fun of me for using olive oil.

According to Healthline, skin type is largely determined by genetic background, with normal being one of the lower-maintenance skin types.

Normal skin types benefit from a balanced production of sebum and moisture, without being excessively oily or dry.

However, experts note that factors such as hormone levels, stress, excessive sun exposure, and certain products can disrupt the skin's natural balance.
