Why wear it? For an extra protective layer between tender skin and scratchy winter woolens.
What does it do? It soothes nerves provoked to a frazzle on the sixth day of an interminably long work week. Waxy labdanum, slippery suede, oily saffron, soapy cardamom, and creamy tonka make for a most unctuous combination. If Prada made a balm version with a lanoline-and-beeswax base, winter (and work!) would never chap me again.
How do I feel? Ameliorated.
