Ingredient reputation (Centella/Cica)
Many buyers cite the Madagascar Centella (cica) formula and its soothing reputation as the main reason for purchase, especially for redness, irritation, or rosacea-prone skin.
Repeat purchase / brand loyalty
A very high number of reviews mention this being their 2nd, 3rd, or even 6th repurchase, showing strong repeat-buy behavior and trust in the SKIN1004 brand overall.
Word-of-mouth / social recommendation
Several reviewers mention buying because a friend, sister, or social media (SNS/TikTok) recommendation prompted them to try the duo.
Value bundle / set pricing
The duo/set format and sale pricing are frequently cited as a reason to buy, with reviewers calling it 'good value for money' or 'economical' compared to buying items separately.
Suitable for double cleansing routine adoption
Some reviewers purchased specifically because they started using daily sunscreen and felt they needed a proper oil + foam double cleanse routine.
