Introduction: UV light is the principal cause of photoaging, a kind of aging. The problem arises because it is less enjoyable. Utilizing the secretome of adipose stem cells (ASC), which is rich in growth factors, could be a novel anti-photoaging therapy. The secretome of ASCs has been extensively examined for their role in wound healing, but their function in photoaging has just lately been investigated. This study looked at changes in epidermal and dermal thickness, expression of MMP-1 and TIMP-1, as well as dermal collagen density to assess the influence of the secretome of ASC in photoaging treatment. Methods: 28 male Wistar rats, 10-12 weeks old, were randomly assigned to one week of acclimation in each of four groups: UV-irradiated group with topical secretome of ASC (Group P1); UV-irradiated group with topical vehicle only (Group P2); only topical secretome of ASC, non-UV-irradiated (Group P3); and non-UV-irradiated and no topical treatment (Group P4) (Group P0). Prior to treating the rats, the UV exposure was administered for six weeks. Then, for a period of four weeks, the secretome ASC was administered as a treatment. Results: The epidermal and dermal thickness were significantly improved after four weeks treatment compared to UV irradiated with topical vehicle only group (p<0.05). The expression of TIMP-1 and dermal collagen density were significantly increased (p<0.05). Conclusion: Secretome of ASC may be a solution for photoaging skin.
