The most comprehensive anti-aging serum in the line. Total RF Serum is built around the RF TriEnergy Complex, which energizes millions of surface skin cells by 200% to work on all the key signs of aging at once — fine lines, uneven tone, loss of firmness and dullness — instead of treating them one product at a time. Who it is for: anyone who wants to simplify a shelf full of single-issue products down to one step that does the heavy lifting morning and night. It is the anchor product of a Regimen rather than an add-on. How to use: apply one pump to a clean face and neck, twice daily, AM and PM, before moisturizer. Give it a full bottle before judging results — the visible change in tone and firmness builds over weeks, not days. When you finish the bottle, keep the reusable glass container and buy the Total RF Serum Refill — the inner vial twists straight in, and it costs less than a full replacement. Size: 30 mL / 1 Fl. Oz.
