Tano Skincare has built its entire regimen around a key healing ingredient: banana sap. The US brand’s story starts with an unfortunate childhood accident in Brazil, where a local remedy stopped founder Sean Finney’s serious injury from becoming far worse.
Finney was nine years old, living in Brazil, when he was dragged across a coral reef while playing in the ocean near Praia do Forte. The damage to his leg was severe enough that his father prepared to apply a tourniquet for the long drive to the nearest hospital. Before that happened, a resident Brazilian man intervened, cutting open the trunk of a banana tree and applying the sap directly to the wound. The bleeding stopped almost immediately.
That experience would sit quietly in the background of Finney’s life for decades before resurfacing as the foundation of a skincare brand built around a patented botanical ingredient.
Finney recalls the moment without embellishment, framing banana sap as practical knowledge rather than folklore. “Those local Brazilians have been using it medicinally for hundreds, if not thousands of years,” he says. “It stops bleeding, it’s antibacterial, and it speeds up wound healing.”
At the time, the incident registered simply as something that worked. In the years that followed, Finney continued to use banana sap in its raw form for everyday skin issues such as cuts, burns, insect bites, and sun exposure. It was yet to be a business venture.
That changed much later, after a career path that took him far from skincare. Finney started out as a Civil Engineer Corps officer in the U.S. Navy, followed by project management at Tesla during the rapid build out of its Texas factory. The commonality across those environments, he says, was learning to operate under pressure and solve problems without perfect information. “Every job you show up to, you’re drastically underqualified,” Finney says. “It teaches you that it’s okay not to know, but it’s not okay not to learn.”
Banana Sap on the Brain: Tano Comes to Life
While enrolled in an MBA program at the University of Texas, Finney found himself with time and structure to revisit the banana sap idea seriously. His initial goal was not beauty. It was medicine. He envisioned banana sap as a battlefield wound care solution, informed directly by his childhood experience and military background. “We actually started as a medical company,” he says. “This saved my leg. We were going to do this as combat wound care.”
That path, however, came with regulatory timelines that would delay real world impact for years. As Finney began testing banana sap more formally, another use case emerged. Early data suggested that the sap had meaningful effects on collagen production, particularly in deeper layers of the skin. That discovery prompted a strategic pivot toward skincare as a faster, more accessible way to bring the ingredient to market.
“When we found out about the retinol comparison and the collagen production, the fastest way to help people was to put it into skincare in a low claims environment,” Finney says.
That decision became the basis for Tano Skincare.
Unlike many brands that rely on readily available actives, Tano is built around banana sap as its central ingredient. Finney distinguishes its behavior from conventional retinoids by focusing on collagen specificity.
Retinoids are well established for stimulating type I collagen, which primarily affects surface level fine lines. Banana sap, by contrast, showed stronger activity in types III and IV collagen, which contribute to structural support and skin thickness.
This distinction shapes Tano’s formulation strategy. Banana sap is positioned as complementary rather than competitive with retinoid alternatives such as bakuchiol. “When you combine bakuchiol with banana sap, you get full spectrum collagen support,” Finney says.
Equally important is tolerance. Banana sap does not carry the same photosensitivity concerns associated with retinoids, which allows it to be used more flexibly and by people who cannot tolerate vitamin A derivatives.
Tano holds a patent on the use of banana sap in skincare, a notable differentiator in a category where most hero ingredients are widely accessible. “We’re currently the only brand in the world using it this way,” Finney says.
That exclusivity did not come easily. Banana sap is not a commercially standardized ingredient, and there was no existing supplier network. Finney had to build the supply chain from scratch. He traveled to Hawaii, knocking on farm doors until he found a grower willing to collaborate. The partnership eventually led him to an organic banana farm run by a banana geneticist whose life’s work focuses on disease resistant banana strains.
The sap is extracted directly from banana trunks that would otherwise be discarded. The process is intentionally minimal, with light stabilization to preserve the sap’s integrity before formulation. The result is an ingredient that remains close to its raw form while meeting safety and stability requirements for cosmetic use.

Tano’s Ethos and Controlled Operations
Product development at Tano follows a similar philosophy. The brand is EU clean, fragrance minimal, and intentionally tight in scope. Much of that discipline comes from Finney’s wife, Annie, who pushed for higher standards early on and acts as an internal quality gate. Her influence helped shape the brand’s emphasis on barrier support, ingredient restraint, and compatibility with sensitive skin.
Clinical testing plays a central role. Tano uses third party labs such as Eurofins for safety and HRIPT testing, and selectively invests in efficacy studies where results warrant further validation. “We’re finishing up an acne clinical right now,” Finney says, noting that the study was prompted by repeated customer feedback rather than marketing ambition.
One of the brand’s most credible endorsements came from a dermatologist who became involved after using the products herself. After exhausting conventional treatments for a chronic skin condition, she saw improvement using Tano’s formulations and reached out to participate more formally in the brand’s clinical work.
Despite national media exposure and steady growth, Tano remains operationally small. Finney and his wife still fulfill orders themselves, packing and shipping products directly. He is also a father of four, a fact that subtly informs how he talks about the business. “We want to show our kids that this is possible,” he says.
The Tano Skincare Assortment
The current lineup reflects the brand’s focused approach:
- The Age Well Face Cream centers on banana sap for collagen support, supported by vitamin C, hyaluronic acid, and barrier friendly botanicals.
- The Reformulate Serum pairs banana sap with bakuchiol to address multiple collagen pathways while remaining suitable for sensitive skin.
- The Banana Balance Cleanser provides a gentle daily reset with light exfoliation.
- On the body side, the lotion and body butter offer two textures built around the same healing first philosophy, with richer emollients in the butter for compromised or sun stressed skin.
