Gift and recommendation seeking
Several reviews mention purchasing as gifts for friends and family, or buying after receiving positive recommendations from others who had already experienced results.
Compact travel format and emergency use
The small set size is frequently cited as ideal for carry-on bags, travel, and keeping as an 'emergency kit' or 'talisman' for unexpected breakouts.
