What Are Exosomes and Why Are They the Future of Skincare?

If you follow skincare closely, you've probably started hearing about exosomes. They're being talked about as one of the most significant breakthroughs in cosmetic science in years — and for good reason.

What are exosomes?

Exosomes are tiny, naturally occurring vesicles — essentially microscopic messenger packages — produced by cells in the body. They carry proteins, lipids and genetic information between cells, playing a key role in cellular communication and regeneration.

In skincare, exosomes derived from plant cells — including apple-derived exosomes — have been shown to support skin renewal, improve the appearance of uneven tone and dullness, and strengthen the skin barrier. They help your skin cells communicate and function more effectively.

What makes them different from other actives?

Most actives work by delivering a single function — vitamin C brightens, retinol renews, hyaluronic acid hydrates. Exosomes work differently. Because they mimic the body's own cellular communication process, they support the skin on a more fundamental level — helping it behave like healthier, younger skin rather than just masking damage.

Who is exosome skincare for?

Exosome serums are particularly suited to anyone dealing with dull, uneven or tired-looking skin, post-acne marks, early signs of ageing, or a compromised skin barrier. They're gentle enough for sensitive skin and can be layered with most other actives.

How to use exosome skincare

Apply after cleansing on clean skin, before moisturiser. Use morning and evening for best results. Commit to at least 8 weeks of daily use before assessing results — exosomes work cumulatively.

Our Exosome and Niacinamide Serum combines plant-derived exosomes with 5% niacinamide for dual-action brightening and barrier support. It's our most advanced formula — fragrance-free, vegan, EU certified and one of the most exciting products in our range.

Pair it with our Peptide Anti-Aging Serum for a comprehensive anti-ageing routine, or layer under the Peptide AM/PM Moisturiser for maximum results.
