Use cosmetics moderately and mindfully without going overboard with spending money on them

This hadith is about the use of collyrium, which is a type of eye makeup used to enhance beauty. It was narrated by Humaid b. Nafi', who reported two traditions from Umm Salama dealing with collyrium and other hadith from the wives of Allah's Prophet, except for Zainab. This hadith teaches us that it is permissible to use collyrium as long as it does not lead to extravagance or wastefulness in spending money on cosmetics or other items that are not necessary for daily life. Additionally, this hadith also reminds us that we should be mindful when using any type of cosmetic product and ensure that we do not go overboard with our spending on such items.
