Repurchase loyalty
A very large share of reviewers explicitly state this is their 2nd, 3rd, 4th, or 5th bottle, indicating strong habitual repurchase driving continued demand.
Ingredient/brand reputation (Centella)
Many buyers cite trust in SKIN1004's Madagascar Centella line or love of the brand's other centella products as the reason they tried the cleansing oil.
Word-of-mouth and viral recommendations
Several reviews mention buying because they heard hype, saw it recommended, or were told by friends/family it works well, describing it as 'viral for a reason.'
Sensitive/acne-prone skin suitability
Buyers with sensitive, acne-prone, or rosacea-affected skin specifically sought this out after other cleansing oils caused breakouts or irritation.
Value during sales/promotions
Some reviewers mention buying during Olive Young sales or because of good value/cost-effectiveness relative to premium price expectations.
