When you make a hidden face in Instagram, it means that your profile picture will not be visible to anyone who is not following you. This can be useful if you want to keep your identity private or if you simply don't want people to see your face. Here's how to make a hidden face in Instagram:
1. Go to your profile and tap the Edit Profile button.
2. Scroll down and tap Private Account.
3. Toggle the switch next to Private Account to turn it on. Your profile picture will now be hidden from everyone except for people who are already following you.
