hey there Hg, yeah i see it there in the picture. Usually what you want to do is to immediately bandage it with opaque tape like duct tape. Leave it too long though, and there's no point. Reason is you're trying to keep light and air out, these hinder the healing and oxidise the wound, respectively. if it's been a lot more than 2-3 , dont bother, but for next time, make a bandage. Hope this helps ! ๐
