Value Bundle Pricing
Consumers frequently cite the set pricing as attractive, purchasing both serum and cream together at a lower cost than buying separately. Multiple reviewers specifically mention it as a 'steal deal' or 'good price range' for the combination.
Repurchase Loyalty
Several reviews indicate repeat purchases and consumption (e.g., 'ordered for the second time,' 'bought 3 units after using the first set'), suggesting strong satisfaction and habituation among core users.
Influencer & Social Proof
One reviewer explicitly mentions buying due to 'signs' (likely influencer recommendations), and another notes skepticism of Instagram fame, indicating significant social media marketing influence on purchase decisions.
Ingredient & Brand Reputation
Reviewers reference ISOI as a established brand with reliable efficacy, comparing it favorably to competitors like Daggal and noting it 'deserves all the hype.'
