"One of the most frequently-reported benefits of astaxanthin is an improvement in skin quality. There is evidence that astaxanthin not only prevents UV sun damage from occurring, but may actually help to reverse external signs of aging from the inside out. This has been clearly demonstrated in human clinical trials.
Many users of astaxanthin supplements report that they are able to spend significantly more time out in the sun without burning than they were able to before. This is due to the powerful anti-inflammatory properties that astaxanthin has. (A sunburn is essentially an inflammation of your skin)."
