DupeScan uses state-of-the-art visual AI to identify the brand, product line, shade, and formulation of high-end cosmetics (e.g., Charlotte Tilbury, Dior, NARS, Fenty Beauty). It then cross-references your item with our curated cosmetic database to match verified drugstore alternatives under $15 from brands like e.l.f., NYX, Milani, and Maybelline.
Ensure your cosmetic product or swatch is well-lit and in focus. For best results, capture the front label showing the brand name and shade name clearly. You can also photograph arm swatches or product textures under natural light.
No. Captured photos and uploaded images are processed in transient memory solely to identify cosmetics and recommend dupes. We never store your photos on our servers, build facial recognition data, or share personal photos with third parties.
