Repurchase of a holy-grail sunscreen
Many reviewers say they already loved and repeatedly bought the Centella sunscreen alone and purchased the duo to restock while trying the serum for the first time.
Bundle value/price
Numerous reviews highlight that buying the two full-size products together is cheaper and better value than purchasing them separately.
Brand trust and ingredient reputation
Reviewers frequently cite general trust in SKIN1004 and the Centella Asiatica ingredient as a reason for purchase, saying the brand 'never disappoints.'
Gifting occasions
Several buyers purchased the set specifically as a gift for mothers, friends, or family due to its attractive packaging and universally liked contents.
Curiosity about the ampoule/serum
A common pattern is buyers who only wanted the sunscreen but bought the set because they were curious to finally try the well-reviewed ampoule.
