New frontiers in aesthetics innovation & anti-aging

What are exosomes?

Exosomes are tiny, membrane-bound vesicles that are released by cells as a means of intercellular communication. These small structures play a crucial role in transferring various biomolecules, such as proteins, RNA, and lipids, between cells. Exosomes are involved in numerous physiological and pathological processes in the body, contributing to cell-to-cell communication, immune responses, tissue repair, and disease progression.  Exosomes are released to communicate with other cells and tissues in order to induce a change cell in activity or behavior.

How are Exosomes made?

Exosomes can be obtained from various cell types and biological fluids through specific isolation methods. Here’s an overview of the general process for obtaining exosomes.  First a culture of skin cells is made in a lab.  As the tissue grows, it releases exosomes.  The desired material is then put through a process called ultracentrifugation and ultrafiltration.  After isolation, the collected exosomes may undergo further purification steps to remove unwanted material.

HOw are exosomes used in aesthetics and anti-aging?

Skin Rejuvenation: Exosomes are being investigated for their potential to promote skin rejuvenation. They may contain growth factors and other signaling molecules that could stimulate collagen production, improve skin texture, and enhance overall skin appearance. Exosome-based treatments are being explored as potential alternatives to traditional treatments like dermal fillers and chemical peels.

Hair Restoration: Exosomes are also being researched for their potential in promoting hair growth and addressing hair loss. It is thought that exosomes derived from stem cells could influence hair follicle regeneration and improve hair thickness and density.

Wound Healing: Exosomes have been studied for their ability to accelerate wound healing. By delivering bioactive molecules to damaged skin tissue, exosomes may enhance the body’s natural healing processes, potentially reducing scarring and improving the appearance of the skin after procedures like laser treatments or surgeries.

 Anti-Inflammatory Effects: Exosomes may have anti-inflammatory properties that could benefit individuals undergoing aesthetic procedures that involve inflammation, such as certain types of laser treatments. By modulating the immune response and reducing inflammation, exosomes could potentially contribute to faster recovery and improved outcomes.

Topical Applications: Exosome-based skincare products are being developed as potential additions to skincare routines. These products may contain exosomes derived from stem cells or other sources, aiming to deliver bioactive molecules to the skin to improve its health and appearance.
