Meder 4MF Active Care Serum Myo-Fix

Myo-Fix is a toxin-free active care serum designed to visibly soften the look of expression lines — the wrinkles that form from repeated facial movement across the forehead, between the brows and around the eyes. It offers a peptide-based, no-needle approach to smoother-looking skin.

Apply twice daily to clean skin, focusing on areas of frequent expression, and follow with a favourite Meder cream to lock in hydration; most people see visible smoothing within 5 to 10 weeks of consistent use. The formula brings together several muscle-relaxing peptides — including Argireline®, Leuphasyl® and Munapsys™ — alongside Matrixyl® 3000 to support the skin's own collagen and elastin, and a Leucidal® probiotic from fermented kimchi to help balance the skin's microbiome. Because retinol and AHAs can interfere with these delicate peptide molecules, it's best to pause other exfoliating actives during a Myo-Fix course.
