Absolutely. The bandwagon effect is a good way to explain how reviews can work. If a lot of people start saying something is good, even if the product is bad, a newly introduced party will be more inclined to believe the product is good. This also applies in the reverse. At the same time, the bandwagon effect is a small factor in todays world due to the influx of "bot reviews", which are basically fake reviews that are almost all good or bad, entirely misleading an objective opinion of a product. When reviews are too mixed, people tend to avoid the product entirely for the sake of reducing complications. All in all, reviews to have a major impact on product sales, but what kind of impact it has can vary extremely.

Wheel spin: the usual wheel spin gimmick. By spinning the wheel, the pointer has 3 options to land on. Option 1 is winning nothing, option 2 is a 50% online discount code, option 3 is a free Avène’s Cicalfate+ Restorative Protective Cream right there and then. Give each of these options a 1/3 distribution on the wheel. The fairness will attract logical students, the chance at a free cream will attract the spontaneous students, and the fact that its AVENE will attract anyone who knows the name and slightly cares about skin.

A healthy skin barrier means a healthy lifestyle. Some people have more trouble with skin care than others, but it's about the effort taken to repair and maintain skin, not just results.
