Is it permissible to work as a sales representative for cosmetics and perfumes according to the mentioned mechanism? Is covering the pictures of immodest women in the brochures sufficient to avoid sin? Is it permissible to promote products made in countries that harass Muslims, such as France?

It is permissible for the sales representative to buy products at the company's discounted rate and sell them to customers, provided the company agrees to and is aware of this; otherwise, it is not permissible, due to the deception and harm it entails for the company. As for obscuring images with a black pen, it is a good and sufficient act, and there is no harm in selling products from non-Islamic countries.
