If you're looking for something like AI Face Analyzer, Facetune could be a good substitute. Although it's geared more for photo and video editing, it's got AI-based features that can help you with your digital life, like skin quality, makeup and beauty filters. The app is designed to be easy to use, so you can use it for casual touchups or more radical transformations, which could be useful for making your face look better.
Another possible alternative is Skinive, an AI-based mobile app designed to help with skin health. Although its main purpose is to identify and track different skin problems, it uses AI to analyze photos of skin, offering risk assessments and guidance on what to do next. The app could help you in a different way, letting you monitor your skin health over time and offering self-examination tools, which could be useful in conjunction with your interest in facial aesthetics.
