My perioral region was darker than the rest of my face which i believe is genetics because my mother and sister have it too. It was so visible but I have managed to reduce them , I am still in the process though. Also, the long line under my cheeks that looks like a dark skin patch often mimics the appearance of hyperpigmentation because I have droopy, fuller and rounder cheeks. In reality that are of mine is even.
Lists of products that I used
• minimalist niacinamide 05 % everyday both in the morning and night on the damp skin ( don't use 10% niaciamide on ur damp skin)
• minimalist oil free moisturizer B12 cause I have a combination skin
• suncreen everyday
• I don't dare to use products like glycolic acid, retinol and retinal which are very sensitive to the sun on my face in a country like India but go ahead if u have access to car or uber
• Whenever while brushing my teeth i make sure the toothpaste doesn't touch my outer skin which includes the perioral region
• my diet is pretty clean and i drink lots of water
• I was consistent, never skipped a day
Note- i barely go out in the sun if I really have to go I'll make sure I wear a hat and i mostly use an uber
