The top 10 neighbors for Ulta Beauty compress into a narrow band — scores running from 0.93 down to 0.89 — with no single dominant pull and no dramatic drop-off. That flat distribution is itself the finding: the audience shape is defined by a dense cluster of Beauty brands, not by any one standout.

Nine of the ten neighbors carry the Beauty subcategory. Urban Decay leads at 0.93, followed closely by Tarte Cosmetics at 0.92, Morphe at 0.92, and ColourPop Cosmetics at 0.91. Anastasia Beverly Hills rounds out the Beauty-brand core at 0.91. The one exception is NikkieTutorials at 0.90, a Lifestyle influencer whose audience composition sits nearly indistinguishable from the cosmetics brands surrounding her — a cross-subcategory match that underscores how tightly this audience cluster is defined by beauty content rather than brand structure alone. FourthRayBeauty (0.90), Too Faced Cosmetics (0.90), NYX Pro Makeup US (0.89), and KVD Vegan Beauty (0.89) complete the set, all Beauty brands, all within four points of each other.

The shape here is a same-kind cluster with almost no cross-category intrusion in the top 10 — an audience that maps almost exclusively onto the cosmetics brand space, with a single lifestyle influencer as the only structural outlier.
