Trial-size testing before full-size commitment
Many buyers explicitly purchased the mini to test a shade or the reformulated version before investing in the larger 30ml bottle, citing fear of not liking the color or texture.
Viral/influencer buzz
Reviewers frequently cite YouTubers (notably Hiro Odagiri) and Korean makeup artists using the product as their reason for trying it, and note it is a well-known 'trending' item that sometimes sells out.
Travel and portability
A very high share of reviews mention buying the mini specifically for travel or to carry in a bag, valuing the compact glass bottle size.
Repurchase/loyalty
Numerous long-term users mention repurchasing (2nd or 3rd bottle) after finishing a previous size, especially fans of the Serenity/lavender and blue shades.
Compatibility with other VDL products
Some buyers purchased after positive experience with VDL cushion foundation, wanting a matching primer step in the same line.
