Biggest tip is to just suck it up. Do not take pain killers or drink alcohol. For aftercare, just use sunscreen if ma expose and bit of petroleum only if itching and sa healing. Never scratch the part na healing and if big pieces like full sleeve, move regularly kase may tendency di naka circulate maayos blood if namamaga na haha. This is only based on my experience and depending pa din sa skin mo and healing ng part.
