Lucia said her forehead lines were less visible after four weeks of using Meder Beauty Science Myo-Fix Concentrate (pictured)
How it works: The serum is a blend of three muscle-relaxing peptides and one that plumps up skin. It should be used twice a day for five weeks, then once a day for five weeks, just once a year. Apply it to each wrinkle with a cotton bud.
My Verdict: After four weeks, my forehead lines were less visible.
Dr Shotter’s verdict: This is the most peptide-rich of all these products, with high concentrations of active ingredients.
