Brand/ingredient reputation (Centella line)
Many buyers already use SKIN1004's Centella ampoule/toner and bought the pads to match or extend that routine, trusting the 'Madagascar Centella' ingredient story for soothing sensitive skin.
Sale and bundle pricing
A very large share of reviews explicitly mention buying because of 'Oliveyoung sale', '1+1' deals, or bundled gifts/samples, showing price promotions are a major purchase driver.
Repeat purchase / loyalty
Numerous reviewers state this is their 3rd, 5th, or 'countless' repurchase, indicating high reorder rates once tried.
Recommendation by friends/social media
Several reviewers cite seeing the product on Instagram or being recommended by a friend before buying, pointing to social proof and influencer-adjacent discovery.
Sensitive/reactive skin needs
Buyers with rosacea, redness-prone, or irritated skin (e.g., from retinol/vitamin C use) purchased it specifically to calm flare-ups, treating it as a 'first aid' skincare item.
