Pretty good
Size: 3-Pack (0.15 Ounce each)
Very helpful to protect sensitive lips. It does have a strong white cast, but it works well.

Soothing sun protection
Size: 3-Pack (0.15 Ounce each)
Very soothing, great protection for your lips. It seems to stay put too, although I’ll reapply a few times during whatever activity I’m doing

Smooth with light white cast but not very strong SPF
Size: 2-Pack (0.15 Ounce each)
Works well, goes on smooth, not too much of a white cast. If you're sensitive to the sun, you may need a stronger mineral SPF that could result in a very white cast.

A little waxy and wears off quickly, but it helped my dry lips this winter.

Smooth and lasts long.

This balm is awesome. Most other chapsticks make my lips worse.
