Exosomes: How the Micro-World Within Us Is Opening a New Era in Cosmetology

We’re used to thinking in terms of tissues, organs, and systems — but forget that everything starts with cells. Tiny, independent units that not only exist, but constantly communicate. And the language they use? Exosomes.

Today, exosomes are driving a revolution in both medicine and cosmetology, unlocking new ways to repair, rejuvenate, and regulate the body's functions.
They’re not just a trendy buzzword — they’re a biological system that has been operating within us for millions of years. And now, we’ve finally learned how to hear it, study it, and harness its potential.

What are exosomes?

Exosomes are microscopic vesicles — or simply, bubbles — filled with valuable information. Inside them are fragments of DNA, RNA, and proteins, acting as messengers between cells. They deliver instructions like: “repair,” “strengthen,” “adapt.”
Messages are sent only within the same cell family — liver cells don’t “talk” to brain cells, only to their own kind.

Types of exosomes

Science today identifies three main categories:

• Animal-derived, including human (further divided into normal and tumor-derived — the latter considered potentially risky);

• Plant-derived, as plants also contain communicating cells;

• Microbial, from microorganisms living in the body or the environment.

Only plant-based and microbial exosomes are permitted in cosmetology — they are safe, non-immunogenic, and easy to purify.
Animal-derived exosomes are reserved for medical research only.

Exosomes: Safety and Myths

Every new technology comes with scepticism. But exosomes were discovered over 60 years ago, and today we have extensive research on their safety. It’s important to note:

• Animal exosomes are banned in cosmetics due to potential allergic reactions and the risk of unwanted cell growth.

• Plant-derived exosomes are the most promising and safest for skincare, especially anti-age solutions.

• Microbial exosomes are the newest and most expensive — with studies actively ongoing.

The Three Main Pathways in Exosome Science

1. External delivery of exosomes — as an active ingredient: extracted, purified, and applied to the skin, often in professional procedures.

2. Stimulation of the body’s own exosome production — through active ingredients that "train" skin cells to generate these vesicles themselves.

3. Exosomes as delivery systems — a true scientific breakthrough, enabling precise transport of active molecules or drugs to specific target cells (currently being explored in pharmaceuticals, oncology, and immunology).

Why exosomes matter in cosmetics

Exosomes aren’t just another marketing gimmick. They’re the language of our cells, a chance for the body to “listen to itself” and restore natural balance.
In cosmetology, this means:
✔️ repair without aggression
✔️ deep-level action
✔️ gentle stimulation of regeneration — in harmony with nature's design.

Why Re[Sens] chooses to stimulate natural exosome production

The flagship anti-age line — 3Action Exosome Boost — is built on the principle of reconstructing the skin’s architecture from the foundational level.

In the 3Action Exosome Boost Serum, 3Action Exosome Cream, and 3Action Exosome Eye Cream, we use a targeted strategy to stimulate natural exosome synthesis by keratinocytes.

Here’s why this advanced approach makes sense:

• Animal and plant exosomes face challenges in transport and storage — they’re fragile and sensitive.

• Animal exosomes are vulnerable to temperature changes and may lose activity.

• Plant exosomes are sensitive to oxidation and humidity.

✅ Stimulating your own exosome production:

• Optimises natural body processes

• Reduces risk of allergic reactions

• Supports balanced cellular communication

• Activates natural skin renewal and visibly reduces signs of ageing — without external interference
