Hannaru maps ingredient overlap across 30 Korean beauty brands

Hannaru has published formula breakdowns for 361 products across 30 Korean beauty brands, using full INCI lists instead of marketing copy. The data shows a small group of ingredients appears across much of the set, giving buyers a faster way to compare lines before placing orders.

Why it matters: - Buyers sourcing multiple Korean skincare brands can now compare formulas side by side instead of relying on line sheets and brand storytelling. - The ingredient counts show which products overlap and which lines are built on different bases, helping buyers spot real differentiation before ordering. - Hannaru says the data can also affect freight and pricing decisions because size bands vary across the catalog.

What happened: - Hannaru began publishing formula data for 30 brands on its B2B sourcing platform for Korean cosmetics. - The first pass covers 361 products, with 352 complete ingredient lists. - The breakdown counts ingredients from full INCI lists, not from marketing copy. - A worked example is available at the 9wishes brand guide.

The details: - Niacinamide appears in the lines of 16 of the 30 brands. - Panthenol appears in the lines of 16 brands. - Adenosine appears in the lines of 15 brands. - Sodium hyaluronate appears in the lines of 13 brands. - Centella asiatica extract appears across seven brands. - Allantoin appears across seven brands. - Ceramide NP appears across five brands. - Products can carry more than one category tag, so Hannaru counts tags rather than products. - The catch-all skincare tag is excluded because Hannaru says it is not informative. - Anti-aging is the most common tag at 97. - Moisturizers follow at 86. - Ampoules total 53 tags. - Essences total 36 tags. - Cleansing accounts for 34 tags. - Masks account for 25 tags. - Toners account for 23 tags. - Sun care accounts for 16 tags. - Hannaru counts size bands the same way, which makes format differences visible for shipping and pricing. - Hannaru updates the counts as the catalog changes, so brand breakdowns are recomputed when listings expand. - Brands enter the set once they have enough products and enough complete ingredient lists to be worth counting, which is why the current set is 30 and not the full catalog.

Between the lines: - The ingredient repetition does not mean the products are equivalent in quality. - The numbers make it easier to see which brands are clustered around common actives and which are built on a different formula base. - Full INCI counting removes a bias in product pages, where brands can emphasize one hero ingredient while omitting another ingredient that is actually in the formula. - The approach shifts the sourcing conversation from brand narrative to product-level comparison.

What's next: - Hannaru says the catalog continues to grow and the breakdowns will change as more products and complete INCI lists are added. - The company lists more than 228 verified Korean brands and 589 products at the product catalog. - Brand profiles are available at the brand directory. - Buyers can request samples from several brands in one tracked shipment through Naru Box. - The catalog is also available on mobile through the Naru Box app.

The bottom line: - Hannaru is turning Korean beauty sourcing into a formula-first search process, and the early data shows a handful of ingredients dominate many lines while category mix still separates brands in meaningful ways.
