Exosomes for Aesthetic Dermatology: A Comprehensive Literature Review and Update
Bibliographic record
Abstract
BACKGROUND: Exosomes are nanoscale vesicles derived from various cell types and tissues that have many potential applications, generating great interest from researchers. One particularly intriguing application of exosomes is their use as a direct therapeutic for aesthetic indications. Several studies and case reports have explored the impact of exosomes for numerous cosmetic concerns but a consensus on the outcomes of these studies has not been established. AIMS: In this review, we summarize the proposed mechanism of action, application, and efficacy of treatments with exosomes for alopecia and hair rejuvenation, facial rejuvenation, hyperpigmentation, and scarring. METHODS: We conducted a comprehensive literature review on the use of exosomes for the treatment of alopecia and hair rejuvenation, facial rejuvenation, hyperpigmentation, and scarring. Additionally, several practical clinical cases where exosomes were applied for these indications were included. RESULTS: The general consensus from the literature review showed that the early evidence supports the efficacy of exosomes for the treatment of alopecia, facial rejuvenation, hyperpigmentation, and scarring. The clinical cases included demonstrated promising improvements in the patients that received treatment. Several limitations regarding the lack of standardization in the production and application of exosomes may limit their current use until more studies are conducted. CONCLUSIONS: Exosomes may serve as a potentially beneficial therapeutic option for several aesthetic dermatologic indications but further investigation is required to fully characterize the scope of their application.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
