According to researchers, sunscreen provides 100 per cent protection against all three forms of skin cancer: BCC (basal cell carcinoma); SCC (squamous cell carcinoma); and malignant melanoma.
Lead researcher Dr Elke Hacker, from QUT's AusSun Research Lab, said sunscreen also shielded the important p53 gene, a gene that works to prevent cancer.
She said that as soon as our skin becomes sun damaged, the p53 gene goes to work repairing that damage and thereby preventing skin cancer occurring, but over time if skin gets burnt regularly the p53 gene mutates and can no longer do the job it was intended for - it no longer repairs sun damaged skin and without this protection skin cancers are far more likely to occur.
The study looked at the impact of sunlight on human skin, both with and without sunscreen, and found no evidence of UV-induced skin damage when proper application of sunscreen (SPF30+) had been applied to exposed area.
The study has been published in the Pigment Cell and Melanoma Research journal.
