I've heard from the traditional scholars such as Zakir Naik and Assimal Hakeem saying that it is not permissible nor encouraged for a woman to upload pictures of herself online even if she wears her hijab properly because they say it defeats the purpose of hijab. However, if something of necessity to gain provision(rizq) like working and business, she has to show her face so that the boss or the customers can know her who she is. Like for example, a resume with her face on it so the recruiter can identify her. Otherwise, it will be difficult and users online will assume that she is a bot if she does not show her face.
Not uploading videos or photos of full face makeup tutorial nor showing off the beauty to anonymous audience nor uploading daily life of the woman. Just the photo of the face for familiarity of employers, recruiters and customers. Nothing more than that. Something that is necessary in this modern, fast-paced world.
