While genetics significantly influence the condition of mature skin, a good skin care routine and a balanced diet are also key.
Speaking on her TikTok channel, skincare enthusiast Yuri Lee revealed that these tips helped her grandma maintain glowing skin at 82.
She told viewers that natto, a staple Japanese food made from whole soybeans, is a daily staple in the octogenarian grandmother's diet.
She told her viewers: “My grandma eats natto every day for her beautiful skin.”
Natto has garnered attention for its potential anti-ageing benefits

Research investigating the benefits of natto for the skin was investigated in a 2023 study published in Cosmetics.
Involving 15 women aged 40 to 65, the study examined the impact of taking 250 mg of natto daily for six weeks on human skin.
The researchers noted: “The results suggested that oral administration of bacillus natto productive protein (BNPP) may significantly enhance skin rosiness and also achieve significant improvement in skin conditions."
These were "defined as complexion, skin elasticity and resilience, moist feeling, skin texture, cosmetic adhesion, fine lines, under-eye darkness, eye bags, sagging cheeks, and sagging mouth".
The scientist studied the protein for its cosmetic potential and found that it could help scavenge free radicals.
However, limitations of the study included the small sample size and lack of diversity in skin complexions.
Beyond its benefits for the skin, natto has also attracted attention for its potential anti-ageing benefits on a cellular level.
Longevity research enthusiast Leslie Kenny recently spoke to GB News about the benefits of taking spermidine - a molecule abundant in natto - for longevity purposes.

The key longevity molecule is found abundantly in plant-based foods, with beans and peas being considered excellent sources of the compound.
“The highest food source of spermidine is in long-fermented Japanese natto,” Kenny explained.
She noted that certain cheeses, like cheddar and parmesan, are also beneficial.
Additional sources labelled powerful autophagy activators were mushrooms, turmeric, and citrus peel.
