Monthly was the right call for me too, weekly just made me obsess over day to day fluctuations. I'm down about 12 on the pill version myself and my face also showed it before anywhere else, so those six week pics of yours line up with what I saw. Sticking to one spot with the same light is what made my comparisons actually usable.
Comparison update posted today at week 6
Monthly is the way to go, I gave up on weekly ones for the same reason. My face slimmed down before anything else did too, and at 32 lbs gone the cheeks are basically where all my proof lives. Same corner, same light every time made my comparisons way more honest.
Monthly makes sense, weekly ones had me staring at nothing but water weight swings too. I'm 21 down and my face was the first place anyone noticed, so your six week side-by-side sounds right on track.
Monthly is where it's at, weekly pics just turned into a water weight scoreboard for me too. Face went first for me as well, around the 20 lb mark people started asking if I'd changed something. One corner, same lighting every time is what finally made my comparisons worth anything.
Monthly worked way better for me too, weekly pics just made me obsess over normal fluctuations. I'm down about 31 lbs and my face is where people notice first, so I get why the side-by-side hit you like that. Same spot and lighting each time is what made mine actually useful.
