I'm curious about procedures I can get 2 days before an important day!

My older sister's wedding is next Saturday, so I'd like to get a quick treatment. I'm planning to get it done around Thursday, and I'm considering Lara Peel + LDM. However, I'm hesitant because I've heard some people experience side effects from Lara Peel. Since it's only two days away, would it be better to just get LDM? It's my first time getting either of these procedures!
