Exosomes are small extracellular nanovesicles that are released by cells, and their potential has been explored for use in cosmetics, skin care, tissue regeneration, and dermatological diseases. The therapeutic value of exosomes lies in their ability to modulate the microenvironment of cells, regulate gene expression, and induce cell differentiation, which can have a positive impact on skin health. In terms of cosmetics, exosomes have been used to reduce wrinkles, improve skin texture and hydration, and enhance skin elasticity, as well as to reduce inflammation and damage caused by UV radiation. Furthermore, exosomes have been used to promote tissue regeneration in skin wounds and to treat dermatological diseases such as systemic lupus erythematosus, psoriasis, atopic dermatitis, systemic sclerosis, pigment regulation, vitiligo, and hair growth. In this review, the therapeutic value of exosomes in the field of cosmetics, skin care, tissue regeneration, and dermatological diseases, has been elaborated. The existing literature demonstrated that with further research, exosomes may become a viable therapeutic option for many skin conditions.
