A Closer Look at the Formula<\/strong><\/h2>\n
Dr. Barbara Sturm\u2019s formula doesn\u2019t rely on just one peptide. Are you ready? You\u2019ve got acetyl octapeptide-3 and hexapeptide-3, often referred to as \u201cneurotransmitter-inhibiting\u201d peptides, which help limit muscle contractions so, over time, expression lines look a little softer. As Dr. Ibrahim explains, \u201cthey work similarly in concept to Botox by dialing down the intensity of repeated facial movements.\u201d Then there\u2019s palmitoyl pentapeptide-4 (a.k.a. Matrixyl), a longtime staple that signals fibroblasts to produce more collagen and elastin. Rounding things out, acetyl-tetrapeptide-2 and decapeptide-4 \u201csupport collagen production and act a bit like growth factors, encouraging overall skin repair,\u201d adds Dr. Ibrahim.<\/p>\n\n

Then there are supporting ingredients, including amino acids\u2014glycine, proline, and arginine\u2014which, as Dr. Safaee explains, \u201care essential building blocks of collagen itself.\u201d In other words, peptides tell the skin what to make; amino acids make it happen.<\/p>\n
And importantly, the formula doesn\u2019t forget about hydration: Hyaluronic acid, glycerin, and a mix of oils and butters keep the barrier intact. Because, as Dr. Ibrahim points out, \u201cthere\u2019s no point in stimulating collagen if your skin barrier is too compromised to function properly.\u201d<\/p>\n
First Impressions<\/strong><\/h2>\n
It\u2019s more milky than I expected from a serum, but it makes sense once you look at the formula: As mentioned, there are water-binding humectants like glycerin and hyaluronic acid, but also emollients and lipids\u2014think shea butter, sunflower oil, almond oil, and vitamin E\u2014suspended into that base. That combination gives it that softly opaque, almost lotion-like look.<\/p>\n\n
