Influencer and social media recommendation
Many reviewers explicitly say they bought it after seeing it recommended on TikTok, Instagram reels, or by a specific influencer, indicating strong social-proof-driven demand.
Reputation for 'no white cast' on all skin tones
Deeper and medium-toned reviewers frequently cite prior disappointment with other sunscreens leaving a cast and purchased this one specifically because of its reputation for blending invisibly.
Alternative/upgrade to other popular K-beauty sunscreens
Numerous buyers compare it directly to Beauty of Joseon, Skin1004 Centella, Round Lab, and House of Hur, suggesting purchases driven by K-beauty sunscreen comparison shopping.
Repurchase loyalty
A large number of reviews mention this being their 2nd, 3rd, or 'many times' repurchase, and some buy multiple tubes at once as backups.
Suitability claims for acne-prone/sensitive/oily skin
Reviewers with oily or acne-prone skin say they bought it specifically hoping it wouldn't break them out, often after struggling to find a suitable sunscreen elsewhere.
