Ultraviolet A (UVA) and ultraviolet B (UVB) radiation are particularly responsible for causing photoaging. Objective: This study aims to identify and compare photoaging rat models exposed to UVA and UVB. Methods: This research method compared macroscopic (scoring degree of wrinkling) and microscopic (histology) signs and symptoms on skin samples of rat exposed to UVA and UVB for 4 weeks at a radiation dose of 840mJ\/cm2. Results: The results of this study indicated that the degree of wrinkling was highest in rat skin exposed to UVB rays by 51% (p&lt;0.05). UVB histological results showed that the epidermis layer (40 \u00b5m, p&lt;0.05) was thickened and the dermis layer (283 \u00b5m, p&lt;0.05) was thinned in the skin of mice exposed to UVB light. The UVB group, showed the density of collagen in the dermis with a mean value of 55% (p&lt;0.05). Conclusion: Our results suggest that short-term exposure to UVB radiation (in the acute, subacute or subchronic phase) induces more rapid and pronounced damage to rat skin when compared to UVA radiation exposure.<\/jats:p>","DOI":"10.5455\/medarh.2024.78.88-91","type":"journal-article","created":{"date-parts":[[2024,3,18]],"date-time":"2024-03-18T11:55:26Z","timestamp":1710762926000},"page":"88","source":"Crossref","is-referenced-by-count":13,"title":["Comparison of UVA vs UVB Photoaging Rat Models in Short-term Exposure"],"prefix":"10.5455","volume":"78","author":[{"given":"Elly","family":"Mayangsari","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arifa","family":"Mustika","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nurdiana","family":"Nurdiana","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nozlena","family":"Samad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3407","container-title":["Medical Archives"],"original-title":[],"link":[{"URL":"https:\/\/ejmanager.com\/mnstemps\/10\/10-1710764206.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T17:57:28Z","timestamp":1791482248000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ejmanager.com\/mnstemps\/10\/10-1710764206.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2024]]}},"URL":"https:\/\/doi.org\/10.5455\/medarh.2024.78.88-91","relation":{},"ISSN":["0350-199X"],"issn-type":[{"value":"0350-199X","type":"print"}],"subject":[],"published":{"date-parts":[[2024]]}}}
