I am convinced that beauty is objective for the most part. It is caused by innate perception, which is confirmed by studies in which infants are already able to distinguish between a beautiful face and an ugly one. Beauty standards change, but really ugly people have never been included in them. We can observe some similarities in the standards of all times of our civilization. Frankly degenerate facial features, baldness, acne have never been in fashion.
If you fit today's beauty standards, there's a 100% chance you'll fit any time's beauty standards, you'll just need to change your wardrobe.
