It is not a proprietary product, so any pharmacy or medical supplier will have it and you are never locked into one brand. Maximum Alpha arrives with a starter tube in the box. The Optimum box holds the device, stand, cable, charger and warranty card only, so order gel at the same time as the device rather than after it lands.<\/p><\/div>\n      <\/div>\n      <div class=\"rule-item\">\n        <svg viewBox=\"0 0 26 26\" fill=\"none\" aria-hidden=\"true\"><path d=\"M4 7h18M4 13h18M4 19h18\" stroke=\"var(--gold)\" stroke-width=\"1\" opacity=\".4\"\/><path d=\"M8 4v18\" stroke=\"var(--gold-deep)\" stroke-width=\"1\"\/><circle cx=\"17\" cy=\"13\" r=\"4\" stroke=\"var(--gold)\" stroke-width=\"1\"\/><\/svg>\n        <div><b data-i=\"sh.b2\">Where the gel goes<\/b><p data-i=\"sh.p2\">On the area you are about to treat, not on the device head, and a generous layer rather than a polite one. Apply it to clean dry skin immediately before you start, because it dries out faster than you expect. A thin layer leaves air gaps between the head and the skin, which is the single most common reason a session stings. Afterwards, pat what is left into the skin or rinse and carry on with your usual products.<\/p><\/div>\n      <\/div>\n      <div class=\"rule-item\">\n        <svg viewBox=\"0 0 26 26\" fill=\"none\" aria-hidden=\"true\"><circle cx=\"13\" cy=\"13\" r=\"10\" stroke=\"var(--gold)\" stroke-width=\"1\"\/><path d=\"M6 6 20 20\" stroke=\"var(--gold-deep)\" stroke-width=\"1\"\/><\/svg>\n        <div><b data-i=\"sh.b3\">Areas that stay off limits<\/b><p data-i=\"sh.p3\">Between the brows, the eyeballs themselves, the lips and the area around the mouth, the nasal bone, the jawbone line, the Adam&#8217;s apple and the thyroid.

Optimum takes the weekly lifting appointment, working deeper than anything else you can hold. Maximum Alpha handles the days in between: firming, microcurrent, and getting your skincare where it belongs. Neither is doing the other&#8217;s job badly, because neither is trying to.<\/p>\n      <p data-i=\"bo.p2\" style=\"color:var(--muted);font-size:15px\">If you are going to own one first, let the depth chart decide it.
