Key takeaways
- FerrinX has partnered with Palmer Holland to distribute NanoFerrin, its precision-fermented, vegan form of lactoferrin.
- The ingredient targets several skin concerns at once, including dark circles, acne, and signs of aging, by binding free iron.
- Precision fermentation removes the dairy-sourcing limits that have historically constrained lactoferrin’s use in cosmetics.

FerrinX has entered a distribution partnership with Palmer Holland for its precision-fermented form of lactoferrin. The US-based biotechnology company developed NanoFerrin to help scale production of a vegan, highly purified, and bio-equivalent form of lactoferrin.
The protein has been used in nutrition for its role in immunity and iron metabolism. It is now increasingly recognized for its antimicrobial, antioxidant, and anti-inflammatory properties for skin care. While Lactoferrin has been studied for its biological activity, it was historically constrained by sourcing limitations, as it comes from milk.
FerrinX says NanoFerrin offers cosmetic formulators a single ingredient that addresses “several of the most persistent skin concerns simultaneously.”
Bret Horace, VP of Consumer & Life Sciences at Palmer Holland, adds: “Our role is to connect world-class ingredient innovation with the brands capable of translating that science into meaningful consumer benefits.”
“NanoFerrin [is] … aligned with the future of biotechnology-enabled skin care.”
FerrinX expects to begin commercial-scale production later this year.
Precision-fermentation for novel formulations
Lactoferrin is a naturally occurring glycoprotein found in mammalian colostrum and other biological fluids. It is known for its role in immune defense and iron regulation. The protein has attracted scientific interest for its potential applications in dermatology and skin health.
Historically, however, commercial access to lactoferrin has been limited, according to FerrinX.
Traditional production requires extraction from dairy sources — an approach that introduces constraints in scalability, cost, batch consistency, and compatibility with vegan or cruelty-free formulations. FerrinX says precision fermentation eliminates these limitations.
FerrinX produces vegan lactoferrin through precision fermentation rather than dairy extraction.
Through controlled microbial fermentation, the bioactive ingredients company produces a bio-identical form of lactoferrin without the need for animal inputs. It says it delivers a product with high purity, reliable functionality, and consistent quality at a commercially viable scale.
Similarly, All G is developing bovine and human milk proteins via precision fermentation for skin care. The Australian biotech company told Personal Care Insights that, given human milk proteins’ biological functions in nutrition and immunity, their use in skin applications is an important area for exploration.
FerrinX asserts that skin care consumers increasingly expect ingredients that combine scientific credibility, sustainability, and ethical sourcing.
In line with this, the European Commission launched a roadmap earlier this month to phase out animal tests in chemical safety assessments. We spoke to Cruelty Free International about the move and how vegan formulations are increasingly present in the beauty industry.
Multifunctional ingredient
NanoFerrin addresses multiple dermatological pathways through a single bioactive.
Dark under-eye discoloration is often caused by iron deposits from microvascular leakage beneath the skin. NanoFerrin binds free iron, helping neutralize the underlying cause of this pigmentation rather than simply masking it with optical brighteners.
Acne-causing bacteria rely on iron for growth and proliferation. By sequestering iron, NanoFerrin disrupts the metabolic pathway these microbes depend on, limiting bacterial expansion while preserving the broader skin microbiome.
Commercial-scale production of NanoFerrin is expected to begin later this year.
Meanwhile, lactoferrin’s well-documented anti-inflammatory properties help reduce redness and irritation commonly associated with breakouts. This dual action presents an alternative to harsher treatments such as benzoyl peroxide that can compromise the skin barrier.
Lactoferrin also influences cellular signaling pathways associated with skin vitality. According to FerrinX, research indicates it can stimulate skin cells to increase production of collagen and hyaluronic acid. NanoFerrin encourages the skin to regenerate these molecules internally, contributing to visibly smoother and more resilient skin over time.
FerrinX says that as biotechnology becomes more integrated into the beauty industry, precision fermentation is emerging as a powerful tool for unlocking previously inaccessible bioactives.
