Why it worked
The video uses a common "guess my age" hook combined with a "before and after" visual transformation, which is highly engaging. The creator's use of the product is demonstrated clearly, making the "after" state directly attributable to the promoted item.
Summary
The creator asks viewers to guess her age, then shows a before and after of her skin after using Centellian24 Madeca Cream Time Reverse. She demonstrates applying the cream to her face and neck, highlighting its wrinkle-reducing and hydrating benefits, and then asks viewers to guess her age again.
