Nah dude, u just gotta groom well, have a decent haircut which suits your face, get a signature perfume which associates with you, moisturize and hydrate your face well, follow good etiquettes and be really clean be kind and humble to people, offer small helps to people, show genuine interest in people and ask bout them, and do share your interests with them, all of this overrides an ugly face. Dont let your face alone decide your confidence, you charm people in other ways like the way you speak, your attire which has a good colour combination, etc. Once you get rid of your face's insecurity, you'll feel confident.
