These Are the Trendiest Skincare Ingredients of 2025

Exosomes

By now, you’ve likely heard the term “exosome” mentioned. Simply put, exosomes are what Engelman calls messenger particles that carry proteins and genetic material to other cells. “In skincare, they are being explored for their potential to support repair processes and boost overall skin health,” she says. “Exosomes used by doctors in clinical settings are typically more concentrated than those in skincare products, and they are often delivered through procedures like microneedling or injections, allowing them to penetrate deeper and work more intensively.” She notes that dermatologists utilize exosomes to accelerate the healing process after specific in-office procedures.

On the other hand, topical exosomes are formulated to sit on the skin’s surface and gradually support its natural repair processes. Engelman says, “They carry key messengers that encourage cells to repair and regenerate, which can lead to smoother texture, improved elasticity, and a more radiant appearance.”

Proponents of exosomes believe they also have a place in haircare routines. Engelman shares that exosomes can help with hair growth by sending signals to the hair follicles to extend their hair growth phase, supporting fuller and healthier strands over time.

Yet, despite the buzz surrounding exosomes, they are not currently FDA-approved, which has sparked some controversy. “While the research is still evolving, exosomes are an exciting innovation that could complement existing approaches to maintaining healthy and resilient skin,” Engelman says.
