I have had redness on the my right side of face?

Hi, I have had redness on the my right side of face. It started around the temple maybe 7-8 years ago and has slowly spread. Trying to figure out if it’s seborrheic dermatitis. It’s not flaky, itchy, burning. No symptoms at all really, just redness. Will include pic. Thanks
