Is it permissible for a veiled female doctor to work in distributing cosmetics to shops, while fearing she may bear the sin of immodest women who will use them?

There is no objection to selling non-prohibited cosmetic products to shops, provided that the Sharia guidelines are adhered to, such as observing the hijab, avoiding seclusion, and not speaking in a soft, alluring manner. As for selling them to individual women, it is stipulated that the buyers should not be those who are known or highly likely to use them for immodest display (tabarruj).
