What eyeliner is safest for the waterline?

Specialist subreddits recommend retractable creamy pencils for tightlining because they don't require sharpening near the eye. The e.l.f. No Budge Retractable and Urban Decay 24/7 Glide-On are the two most frequently cited, though reviewers note even 'waterproof' waterline wear is typically 4-8 hours before fading.
