Hannah Tyrrell will make her first start of this year's Six Nations campaign as Ireland head coach Adam Griggs has largely shown faith in the same side that beat Wales last time out.
Scotland visit Donnybrook on Sunday, when Ireland bid to win their third game on the bounce before a trip to England.
Tyrrell missed the start of the campaign due to Sevens commitments but she came off the bench against Wales to good effect and has forced her way into the starting XV on the left wing.
Hooker Cliodhna Moloney is also promoted as she makes up a powerful front-row alongside Lindsay Peat and Leah Lyons.
"We came away with a good win against Wales and there are some huge positives to come out of that," said Griggs.
"We are in a good place going into the final two games. I've no doubt Scotland will be looking to push us hard on Sunday.
"If we replicate our last performance, get the small things right, I am confident we will have a successful outcome."
