First, gently exfoliate your face every day to get rid of the dead skin cells that can cause ingrown hairs.
And make sure to adopt correct shaving technique, using a rich shave cream that softens hair, protects skin and prevents irritation.
Follow with a moisturizer to keep your skin smooth and hydrated.
Ingredients to look for are Shea Butter (to protect and nourish), Tea Tree Oil (to purify and stop irritation) and Apricot Stone Oil (to soften hair).
