How does the cooling-then-warming sensation actually work?

The sensation comes from two actives that trigger different nerve receptors in sequence. Levomenthol activates cold-sensitive TRPM8 receptors almost immediately after application, so the skin feels distinctly cool within the first minute or two. Methyl salicylate works more slowly; it acts as a counter-irritant that gradually stimulates warmth-sensitive pathways, producing a building heat that typically peaks after the initial coolness fades. This contrast is intentional — the shift from cold to warm can redirect attention away from a feeling of local stiffness or heaviness. The petrolatum and paraffin base slows the release of both actives, so the transition feels gradual rather than abrupt, and the layer stays in place long enough for a thorough massage. You will not get the same effect from a water-based gel that evaporates quickly; the ointment base is a functional part of how the sequence unfolds.
