- Wash thoroughly.
- Get proper rest.
- Have nutritious meals.
- Keep yourself active.
- And limit your consumption, engagement and participation with anything stressful, overwhelming, and/or exhausting (yes, even if they're people and places you don't always hate).
While I'm not against makeup or surgery in certain cases, it is still best to tend to the above first instead.
Furthermore, treat yourself to anything that gives you peace or joy that isn't harmful! It greatly helps your natural glow.
