BEFORE :

The video effectively uses a 'before and after' format over a 7-day period to demonstrate the product's efficacy, making the results tangible and persuasive for viewers concerned with acne and breakouts.

The video shows a 7-day skincare routine using Purito Seoul's Azelaic Acid & Tea Tree Serum. It begins with a 'before' state, then demonstrates the application of the serum daily for a week, and concludes with an 'after' state showcasing the results.

Purito Seoul Azelaic Acid & Tea Tree Serum: This is a serum that is applied to the face to help with acne and breakouts. It ACTS by being applied to the skin. Removing it would change the video's demonstration of its use and results. Purito Seoul: This is the brand name of the serum. It merely APPEARS as part of the product name. Removing it would not change what happens in the video.
