Are (retinol) eye creams dangerous?

Hi! I was watching a video on youtube the other day warning against using eye creams that contain preservatives (though not clear which) and retinol - and therefore against using eye creams in general. Do you know anything about this concern? Video link is https://youtu.be/hql6k88BKP8 retinol issue at 4.25 and preservatives just before.

More broadly what would be some good and safe options for eye area for anti-age and under eye bags?

Thanks for any tips!
