The XO-Cargo™ Platform

The skin’s own communication system

Every synthetic delivery system is engineered to behave like biology, without being it. XO-Cargo™ exosomes are biology. The body’s own delivery infrastructure, evolved over 300 million years of mammalian evolution to carry cargo with precision and efficiency no engineered system can replicate.

Why Milk?

Ethically sourced from pasture raised cows, milk exosomes have three specific advantages.

01Natural abundance: Bovine milk is one of the richest and most consistent natural exosome sources available, enabling the industrial-scale production that has eluded every other exosome platform.
02Biological compatibility advantage. Bovine milk exosomes share the same fundamental biology as human exosomes – structurally compatible in a way plant-derived and synthetic alternatives cannot replicate.
03Consistency: Human-derived exosomes carry donor variability, regulatory risk and are often challenged by commercial scale. Plant-derived EVs (these are not technically exosomes) lack mammalian biological compatibility. Milk exosomes solve all of these challenges.

Naturally loaded with skin-enhancing cargos.

Milk exosomes naturally contain skin-enhancing proteins, lipids, and fatty acids – shown in independent clinical testing to visibly improve the appearance of skin elasticity and wrinkles.

Most delivery systems are empty vehicles whose performance depends entirely on what is loaded into them. XO-Cargo™ is different. Milk exosomes are the delivery system and the active ingredient in one.

XO-Cargo™ ME

Our pure, naturally loaded milk exosome ingredient.

Delivering clinically proven improvements in the appearance of skin elasticity and wrinkles. The milk exosome is the active ingredient.

We have amplified the natural power of milk exosomes with proprietary Precision Loading.

For the first time in cosmetics we have encapsulated a proprietary peptide inside an exosome — enhancing absorption and efficacy, while removing irritation.

Enhanced Efficacy

The exosome’s natural delivery capability amplifies the performance of any loaded active.

No Irritation

Loaded actives don’t contact the skin surface as free molecules, removing the potential for sensitivity associated with traditional delivery methods. 0.0 HRIPT validated across all subjects.

Long-Term Stability

Lyophilization locks the loaded active inside the exosome, stabilizing it for the full shelf life of the product.

Cost Efficiency

Actives precision-loaded into XO-Cargo™ exosomes can achieve clinically proven results at significantly lower inclusion levels than free actives require — reducing formulation cost without compromising performance.

XO-Cargo™ AA

Our peptide loaded milk exosome ingredient.

A proprietary dermal elasticity peptide, precision loaded inside an XO-Cargo milk exosome, delivering rapid clinically proven improvements in the appearance of skin elasticity at day 14.

In Development

The platform is expanding

Two further precision-loaded variants are in active development — extending clinically proven exosome delivery into new cosmetic categories.

XO-Cargo™ ST

Precision-loaded milk exosome variant targeting improvement in the appearance of skin tone, redness and blemishes.

XO-Cargo™ HR

Precision-loaded milk exosome variant for cosmetic hair-care applications.
