The mechanism
What a scrub lifts off, and what it leaves alone
Exfoliation has one mechanism: an abrasive medium plus steady pressure lifts the layer of loose surface cells that has stopped shedding as tidily as it did in July, and there is no more mechanism to it than that. In a wet, heated Northwest winter that layer builds faster on shins, forearms and heels than it does anywhere else, which is why those are the places people notice first when they run a hand down a leg in February. Sixty minutes and $120 buys the version that reaches all of them in one appointment.
The payoff people actually notice comes afterwards. Moisturizer applied to freshly exfoliated skin tends to feel like it goes further, because there is less loose material sitting between the product and the skin. Feel is the honest verb there. A scrub does not treat eczema, psoriasis, keratosis pilaris or anything else with a diagnosis attached, and it is not a substitute for medical care — skin that is changing, itching or refusing to settle is a dermatologist's question, not a spa's.
Tell the therapist what is going on before the session starts: recent sunburn, a rash, a new tattoo, a healing cut, a condition under treatment. Pressure and coverage can both be adjusted, and an area can be skipped entirely. NCCIH's safety guidance for massage therapy makes the same general point about hands-on treatment: the practitioner should know your health situation, and your doctor should know what you are trying.
The published menu gives the service, the length and the price and then stops. It does not say which scrub medium is used, or what goes on the skin afterwards. If you have a fragrance sensitivity, or a known reaction to a common oil or exfoliant, call (425) 497-9700 and ask before booking rather than finding out face down.
