I look for the target problem driving the reviewer's need for the problem and the type of skin they have (e.g dry, sensitive, oily etc.)

I love to know how long the product what being used, how the packaging was good or bad, if there were any adverse reactions, how strong the scent is, and if its a face product how it sits under makeup.

I also love to see pictures of the packaging, and if possible before and after pictures of the skin.

Yes, I have.

Over 30 days I notice real changes in skin smoothness, brightness, and even bloating; skin is the largest organ and it responds to everything. For this trial I would document specific areas of my body with daily photos and short video check-ins capturing how I feel in the moments after my morning and nighttime showers, and also how my skin feels the morning after a nighttime shower to capture the overnight effect. At the end of 30 days I would compile the photos into a labeled time-lapse and cut the video clips into a progression showing the full arc. That kind of documentation is more credible than a single before-and-after because it shows the actual journey.
