Epidermal proliferation not affected by age in photoexposed and photoprotected sites. (A) Representative immunofluorescence images of human skin obtained from (i, iii) photoprotected buttock sites and (ii, iv) photoexposed dorsal forearm sites of (i, ii) a young 22 year old donor, and (iii, iv) an ageing 64 year old donor. (i–iv) Immunolabelling of Ki67 and DAPI nuclei staining. Scale bars: 50 μm. (B) The % Ki67 of the epidermis from photoprotected and photoexposed sites in young and aged individuals with Fitzpatrick II‐III skin types (n = 10 donors per category). Mean values ± SEM are displayed, ns Q > 0.05.
