An 80-year-old grandmother went viral because she has perfect skin with hardly any wrinkles.

Business Insider US asked her granddaughter what her grandmother does to look so young.

Among other things, she follows a long skin care routine, takes daily supplements and eats a lot of fermented foods.

Wrinkles, sun spots and fat loss are a natural part of the aging process of the skin. But this 80-year-old seems to have (largely) avoided all of that.

When Yuri Lee, a 36-year-old LA-based influencer, posted a TikTok video with her grandmother Toshiko Eto last fall, it went viral. In the video, she shows off her “flawless and glowing glass skin” that she achieved without Botox or fillers, and people commenting were eager to know the 80-year-old’s skincare secrets.

Lee told Business Insider that her grandmother has been taking care of her skin since she was 20. On TikTok, she said that she is very consistent with her skincare routine and “if she likes something, she sticks with it.”

The global skin care market has almost doubled in size in the past decade. Business Insider US asked dermatologists whether Eto’s skin care routine or simply luck and genetics helped her achieve flawless skin.

Eto has had a skin care routine for 60 years

Eto has been caring for her skin daily for 60 years and has been using special products from the Japanese brand Manavis for 15 years. These are:

Emollient Lotion – a facial spray that she not only sprays on, but also dabs in.

Dr. Derek V. Chan, a board-certified medical and cosmetic dermatologist in Manhattan, told Business Insider US that the active ingredient in this lotion is dipotassium glycyrrhizinate, which is said to even out skin tone and maintain hyaluronic acid levels. However, evidence from large-scale studies is still needed to back up these claims.

Whitening Essence – Eto applies a burst of this vitamin C serum to her skin.

Chan explains that the form of vitamin C used in this product helps repair UV damage, increases collagen levels, and is “a great way to get the benefits of vitamin C without irritating the skin.”

Restore Gel – Eto applies this serum after the Whitening Essence. On TikTok, she said that she doesn’t wait between products because they absorb quickly.

The tranexamic acid in this gel can reduce hyperpigmentation, says Chan.

Wrinkle Gel – this is a moisturizer that Eto massages in.

Chan said some manufacturers claim that the stearyl glycyrrhetinate contained in this product can smooth the skin, but that too needs further research.

La Prairie Foundation – Eto says this foundation is “very light on the skin” and acts like a tinted moisturizer that lasts all day.

Chan likes this product because it contains ceramides, which help restore the skin’s natural barrier, as well as physical and chemical sun protection. However, since the American Academy of Dermatology recommends a sunscreen with an SPF of 30 or higher, “this foundation should be used in conjunction with another sunscreen to ensure adequate protection against the aging effects of ultraviolet light,” he stressed.

At night, Eto uses the Nerium Age Defying Night Creamwhich is available in the US, Lee told Business Insider. Eto has been using it daily for ten years, applying it after her evening bath.

Avoiding sun exposure prevents wrinkles

In response to comments on her videos, Lee said her grandmother “doesn’t go outside much.” According to the Skin Cancer Foundation, the sun is responsible for 90 percent of visible skin damage.

Dr. Tina Alster, dermatologist and director of the Washington Institute of Dermatologic Laser Surgery, told Business Insider US that genetics and sun protection are “probably the two most important factors” in keeping Ego’s skin looking so young.

Alster said that Oto’s skincare routine probably contributed “minimally” to her wrinkle-free skin and that so many steps are unnecessary. She said, “If the vitamin C serum is the right strength/formulation, it’s probably the best product in her regimen.”

Daily intake of nutritional supplements, including protein powder

For 20 years, Eto has been drinking soy protein powder and vitamin C powder from a Japanese brand called Miki, mixed with plum extract in a shake every day. She also takes Miki’s Eco 37 supplement, which Lee says is made from avocado oil.

Chan said research shows that adequate protein intake is good for skin health. Additionally, vitamin C helps protect skin from the sun and is linked to reducing wrinkles, according to Oregon State University.

Eat lots of fermented foods

Eto claimed in a TikTok video that it’s not the Manavis anti-wrinkle gel she applies to her skin, but the foods she eats that keep her skin supple. According to Lee, Eto eats a big breakfast every day and cooks most of her meals at home. Her grandmother’s diet also includes lots of vegetables and fermented foods, including kimchi, miso and natto, a traditional Japanese food made from fermented soybeans.

As gastroenterologist Will Bulsiewicz explained to Business Insider, fermented foods are good for gut health, which impacts overall health and longevity. In addition, research suggests that gut health and skin health are linked.

Alster added, “Fermented foods may or may not be helpful. The most important factors for healthy, rejuvenated skin are genetics and sun protection.”
