Exosomes are tiny extracellular vesicles produced by cells. Scientific reviews classify exosomes as 30–200 nanometres in diameter and note that they contain proteins, lipids, and nucleic acids (such as mRNAs and microRNAs)[1][2]. Because of their nano‑scale size and rich cargo, exosomes act as intercellular messengers, shuttling biological signals from one cell to another. Stem‑cell–derived exosomes can carry growth factors, cytokines and regulatory RNAs that support skin homeostasis. Studies on skin aging and photoaging report that exosomes help increase collagen and elastin expression, reduce inflammatory pathways and aid wound repair, leading to improved skin firmness and elasticity[3]. In skincare, exosomes are prized for delivering these bioactive cues without introducing living cells.

Most cosmetic ingredients—such as moisturizers, peptides or antioxidants—work by coating the skin or targeting single pathways (e.g., increasing moisture or reducing free radicals). Exosomes are different because they act as biological messengers: they deliver molecular instructions that help skin cells rejuvenate themselves. Research shows that exosomal cargo can increase collagen and elastin production, improve hydration and suppress inflammatory mediators[3][5]. In essence, exosomes support the skin’s own renewal processes rather than simply masking signs of aging.

Regenera uses exosomes derived from human umbilical‑cord mesenchymal stem cells (UC‑MSCs) sourced and processed in the United States. Published work highlights that UC‑MSC exosomes provide a high yield of vesicles and can be collected without invasive procedures or ethical concerns[6]. Donor umbilical cords are obtained with informed maternal consent following full‑term births. Compared with exosomes from adult tissues, umbilical‑derived exosomes tend to contain a richer array of growth factors and are viewed as more potent in regenerative applications.

Each millilitre (mL) of Regenera’s serum contains approximately 600 million exosome particles. The quantity is measured by nanoparticle analysis to ensure consistency and potency from batch to batch.

Exosomes are acellular, meaning they lack nuclei and cannot replicate. Scientific reviews note that exosome therapies are cell‑free and have lower risks of tumorigenicity or immune rejection compared with stem‐cell therapies[4]. Regenera’s exosome preparations undergo sterile filtration and endotoxin testing to ensure they are free from bacteria, mycoplasma and viruses. The final cosmetic serum contains a preservative system (free of artificial colours or fragrances) to prevent microbial contamination. Because exosomes do not carry whole genomes, they cannot introduce genetic material into skin cells; they simply deliver transient signals

Regenera’s Exopure Booster Serum is formulated to visibly improve the appearance of skin. Based on user feedback, reported benefits may include:

• Reduced appearance of wrinkles and firmer skin: Enhanced collagen and elastin support firmer, smoother skin.
• Brighter tone and smoother texture: Exosomal signals can help even skin tone and refine texture, leading to a more radiant complexion.
• Improved hydration and elasticity: Exosomes encourage the production of hyaluronic acid and other moisturizing factors, increasing skin moisture and suppleness.
• Calmer, less red skin: Anti‑inflammatory mediators in exosomes help reduce redness and irritation.
• Refined pores and overall glow: Users often notice smaller‑appearing pores and a general improvement in skin clarity after consistent use.

These benefits arise from supporting the skin’s natural renewal rather than from adding new cells or tissues. Individual results may vary.
