Brand trust from other RoundLab products
Many buyers already used RoundLab's Dokdo toner, cleanser, or sunscreen and purchased this cream to complete the line, trusting the brand's gentle, dermatologist-style reputation.
Repurchase/loyalty
A large share of reviewers explicitly mention this being their 2nd, 3rd, 4th, or even 6th repurchase, indicating high retention once tried.
Value/price-to-size ratio
Reviewers frequently cite the large tube size, mini bonus size, and affordable price as reasons to buy, especially during sales events.
Suitability for oily/combination skin
Many buyers sought a non-greasy moisturizer specifically because prior creams felt too heavy, and chose this product based on its reputation as lightweight and oil-control friendly.
Gifting
Several reviews mention buying it as a gift for spouses, sisters, daughters, or friends, sometimes explicitly citing the special set format as ideal for sharing multiple items from the line.
