In my exploration of makeup that best conceals scars, I've found that using a high-coverage foundation and concealer can really do wonders. The first step is to use a primer which smoothens the skin's texture and prepares it for makeup. Then, apply a color corrector that suits your scar's undertone before layering on a full-coverage foundation. For a seamless finish, set the makeup with a setting powder. Remember, the goal is to blend the makeup into your skin tone, not mask the scar completely - you are beautiful just the way you are.
