If the in-game description of "Skin Clear" is to be believed then Steele having the lubricated skin flag, means that they're secreting a sweat. However, the "Pheromone Sweat"-perk doesn't activate with it at all.
At least reading the scene, when Steele acquires lubricated skin via the item, gave me the impression that it would at least "award" the lower level bonuses of "Pheromone Sweat".
Skin clear description (the last part of it):
Shortly after, your skin begins to glimmer, the torrential output of liquid slows to a crawl. It doesn’t stop, though, continuing to cover you in a perpetual layer of slickness. Shrugging, you experimentally brush a hand across the surface of your body, shivering as it slides across your newly lubed skin.
Edit:
When Steele's skin already has the "aphrodisiac" tag, then adding "lubricated" to it, also describes it as aphrodisiac sweat in the character description.
