These can be used anywhere- eyes, lips, cheeks, face… and make amazing highlighters and strobing powders. Use over different bases for different effects. These have a fine, lustrous/satin finish.\n\n\n\n\n\n\n\nCepheid Variable has a buff base which flashes blue.\n\n\nThis shade is inspired by the galaxy Zwicky 18, which contains cepheid variable stars which allowed astronomers to more accurately date the age of the galaxy. From Hubble’s newsroom: \"NASA's Hubble Space Telescope quashed the possibility that what was previously believed to be a toddler galaxy in the nearby universe may actually be considered an adult. Called I Zwicky 18, this galaxy has a youthful appearance that resembles galaxies typically found only in the early universe. Hubble has now found faint, older stars within this galaxy, suggesting that the galaxy may have formed at the same time as most other galaxies. Hubble data also allowed astronomers for the first time to identify Cepheid variable stars in I Zwicky 18, marked by the red circles. These flashing stellar mile-markers were used to determine that I Zwicky 18 is 59 million light-years from Earth, almost 10 million light-years more distant than previously believed.”\n\n\n\n \nContains: Mica, Titanium Dioxide, Carnauba Wax, Iron Oxide, Boron Nitride, Dimethicone, Isododecane\n \n\nAvailable in two size options (Mini size jar has custom label art):\n\n\n\nMini Jar (aka \"10 gram\" jar) holds approximately 4 grams net weight of product.\n1/4 teaspoon in a 2x2 inch zip baggie - baggie samples are available in sets only.\n\n\n\n\n\nNOTE: While we have made all attempts for photographs to accurately depict colors, photography unfortunately does not accurately reveal the depth and interplay of color and effect of these shadows. Also, please note that variations do exist between different computer monitors.\n","images":["https://cdn.shopify.com/s/files/1/1375/1919/products/CEPHEIDvariable.grid__87611.1448578810.1280.1280_f7fd744b-ddb8-4941-be08-ede021ef7ae3.jpg?v=1604534813","https://cdn.shopify.com/s/files/1/1375/1919/products/CEPHEIDvariable.grid.nebula__56351.1448578813.1280.1280_f375bc88-3b93-41cd-a2e6-6b765b1984c7.jpg?v=1658000132","https://cdn.shopify.com/s/files/1/1375/1919/products/Cepheid.Variable.DSC_0002__42862.1448578862.1280.1280_cf1e13a9-f374-49e0-8cd8-73700368ff95.jpg?v=1604534813","https://cdn.shopify.com/s/files/1/1375/1919/products/Cepheid.Variable.DSC_0014__53607.1448578873.1280.1280_aecbd9c0-aa65-4e93-a682-e4befd195e75.jpg?v=1604534813","https://cdn.shopify.com/s/files/1/1375/1919/products/Cepheid.Variable.DSC_0018__80744.1448578876.1280.1280_13bb5717-b9b0-4c77-a4c9-189bd3de7afc.jpg?v=1604534813","https://cdn.shopify.com/s/files/1/1375/1919/products/CepheidVariable.DSC_0001__46740.1448578886.1280.1280_190035cb-f73f-47e0-a5f5-1737a881ea5e.jpg?v=1604534813","https://cdn.shopify.com/s/files/1/1375/1919/products/12295515_1084520554905797_3441714996840444589_n__50173.1448579009.1280.1280_a093a35f-4ed7-4252-8a90-b7864573665f.jpg?v=1604534813"],"price":6.74,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:59.587Z"},"share_url":"https://firestarter.network/l/lst_MBgzC7q1","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
