It can also reduce the pain and inflammation occurring with sunburn. The objective of course is to not get sunburned at all. Not to be mistaken, Astaxanthin is not a replacement for sunscreen, but sort of functions as internal sunscreen. I have been trying to find out if there are actual studies with regards to the SPF of Astaxanthin, but couldn't find anything. It reaches its effect after ~2 weeks of taking 4mg a day.
Some cites refer to increased protection against the sun and state the Astaxanthin is 500 times stronger than Vitamin E and 10 times stronger than beta-carotene, which in the past have been recommended to aid exposure to sun.
As many of us I am usually a little skeptical, when it comes to supplements, especially if there is so much different information available online, but no profound scientific studies. I am giving it a try and will let you know what my experience is. The antioxidant also shows significant other benefits. Just Google Astaxanthin + benefits and you will be surprised :)!!!
