A comprehensive paper concerning the dermal effects of sun exposure, including strategies which aesthetic nurses can adopt to guide patients in making evidence-based choices in selecting suitable sun protection. The key principles of ultraviolet radiation (UVR), including the immediate and long-term effects are explored. Whilst a plethora of information is available describing the dangers of prolonged sun exposure, the author acknowledges the inconsistent and often conflicting nature of guidance from official bodies. The cellular process behind replicative senescence and the Hayflick Limit is conveyed, as the basis for an interesting comparison with stem cells. The author provides a detailed overview, including the definitions of melasma and hyperpigmentation, solar elastosis, solar lentigines and poikiloderma amongst other UV related conditions. Sun protection factors, including standard test methods, physical and chemical sunscreens are explained with clarity. A useful paper to support aesthetic nurses in maintaining a current awareness of the effects of UV radiation as well as providing insight into the definitions of common sun-related lesions and conditions.
