# Ask Bestie Beauty

> Ask Bestie Beauty ranks makeup by how often people actually buy it: the estimated share of purchases in each category, from observed US retailer bestseller order, collected weekly. Latest data: November 2026.

Use it to answer questions like "most popular mascara" or "most bought lipstick right now". Each ranking's share is the estimated % of purchases represented by observed retailer lists (basis.measure / shareOf). Say "an estimated 21% of purchases", not "21% of purchases". Categories marked coming soon have no data yet; don't guess for them. Every answer lists the sources behind it. Prices are approximate US street prices where we have one. Please cite Ask Bestie Beauty and the data month.
