Protecting your skin against the harmful effects of ultraviolet radiation is an absolutely essential part of maintaining skin health. UV radiation is not only the biggest cause of premature ageing but it is also implicated in skin cancer formation. Excessive exposure to UV radiation from the sun must be kept to a minimum although it is important to know that some exposure is required to help your skin produce Vitamin D.
Ultraviolet radiation is a potent source of oxygen free radicals which are the molecules that set off a dangerous chain reaction in the skin that ultimately leads to collagen & elastin breakdown and DNA damage.
Use of PHOTOPROTECTANTS (traditionally termed sunscreens, sun creams, SPFs) are therefore essential to block the harmful effects of UV light. However, topical ANTIOXIDANTS should be also to be used to minimise free radical damage too.
The latest photobiology research suggests that infrared and visible light might also contribute to the ageing process too. Therefore a ‘broad-brush’ approach to photoprotection should be used. Traditional sun creams dont do a complete job.
Dr Deigan’s Advice
Dr Deignan strongly recommends you use the very best SPFs possible to protect your skin and to be safe in the sun.The scientific field of photobiology is advancing rapidly. UV protection in all it’s forms is essential for our skin both from an anti-ageing perspective but also to help prevent skin cancer.
