Matrixyl Dosage Calculator

Matrixyl is topical. No vials, no reconstitution, no syringes. That alone makes it the easiest peptide in most people's stack. The concentration math trips everyone up. "10% Matrixyl complex" on a label does not mean 10% pure peptide. Actual Pal-KTTKS content in a "10% complex" product sits around 0.003 to 0.005% (3 to 5 ppm). The Robinson RCT used just 3 ppm and still hit significance. So those retail numbers are in the therapeutic range; they're just confusingly labeled. For DIY formulators: dissolve raw Pal-KTTKS powder at 0.0003 to 0.0008% w/v in a water and glycerin base. Target pH 5.5 to 6.5. The palmitoyl ester bond is acid-labile below pH 4. Add 0.5% phenoxyethanol plus 0.5% ethylhexylglycerin for preservation. Refrigerate and use within three months. Apply to clean, dry skin. Wait two to three minutes before layering moisturizer. Twice daily, morning and evening. The non-obvious thing most beginners miss: applying over a heavy cream blocks penetration. Matrixyl goes on bare skin, not on top of your routine.
