"Thanks to frequent checks & amazing doctors, all's well," Jackman wrote in the caption. "Looks worse w/ the dressing on then off! WEARSUNSCREEN."
Jackman was first treated for basal cell carcinoma -- the most common form of skin cancer -- in 2013, and has since undergone at least five operations to remove cancerous cells. Along the way, he's always made sure to stress the importance of sunblock.
In May 2014, Jackman attended the red carpet premiere of X-Men: Days of Future Past just days after getting surgery, and rocked a white bandage on his nose while posing for photos. Check out the video below to see more.
