XRCC1
The XRCC1 gene is involved in the efficient repair of DNA single-strand breaks formed by the exposure to UV rays from the sun.
If you have medium to high impact genetic variation in this gene, could mean that you will have a decreased efficiency in repairing cellular damage. It is advisable to provide your skin with non-toxic, sun protection and repair as well as increase your antioxidant intake.
A flavonoid-rich diet is recommended to improve DNA repair, and specific oral supplementation shown to have beneficial effects in this area include resveratrol, selenium, and carotenoids such as astaxanthin.
