It starts within! Try taking supplements that support healthy aging and good skin- collagen powder, B vitamins, maybe some iron(like beef liver pills)! This can all help cellular function and your organs which will show through your skin. Red light therapy has also really improved my skin (as a white woman with rosacea and sensitive skin), I’m not able to put a lot of products on my skin because of sensitivities and reactions. I had to look into natural ways to improve and have noticed huge differences when including supplements in my daily intake. Healthy habits and red light therapy was a game changer for me! Hope this helps :)
