There are four families: signaling peptides, transport peptides (copper peptide), peptides that act on neurotransmitters (dynamic wrinkles) and growth factors such as EGF. They offer gentle anti-aging action, without the irritation of retinol.<\/p><div class=\"bd-hero-meta\"><div class=\"bd-hero-meta-item\"><span>Family<\/span><strong>Amino acids (cell signalling)<\/strong><\/div><div class=\"bd-hero-meta-item\"><span>Method<\/span><strong>Verdict Sensitivity - Dr David's rule<\/strong><\/div><div class=\"bd-hero-meta-item\"><span>Selection<\/span><strong>4 serums rated by BeautyDecoders<\/strong><\/div><\/div><\/div><\/section><section class=\"bd-section\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">Definition<\/span><h2>What is a\u2019<em>a peptide<\/em> ?<\/h2><p class=\"bd-lead\">Peptides or growth factors such as EGF are sometimes described as \u00abbotox in a bottle\u00bb. Here's a more objective view of their value in facial care, a selection of the best serums, and above all, when not to apply an EGF-based product.<\/p><p class=\"bd-lead\">Peptides are assemblies of amino acids, like proteins. The difference: a protein is a very long chain of amino acids, often with a 3D structure, whereas a peptide is short. In humans, 20 amino acids make up all proteins. In cosmetics, peptides are of interest because they act at the heart of cells, sending them messages: produce more collagen to reduce wrinkles, or less pigment to reduce blemishes.<\/p><\/div><\/section><section class=\"bd-section\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">The families<\/span><h2>The 4 categories <em>peptides<\/em><\/h2><div class=\"bd-prob-grid\"><div class=\"bd-prob-card\"><div class=\"bd-prob-num\">01<\/div><h4>Signaling peptides<\/h4><p>They send a signal to cells to produce more collagen, elastin or hyaluronic acid. The most studied are Matrixyl and Matrixyl 3000, found in many anti-aging serums.<\/p><\/div><div class=\"bd-prob-card\"><div class=\"bd-prob-num\">02<\/div><h4>Transport peptides (copper)<\/h4><p>They carry minerals such as copper and manganese. Copper peptide, a natural tripeptide discovered by Dr. Pickart almost 50 years ago, is widely studied: it increases the production of collagen, elastin and hyaluronic acid by dermal cells.<\/p><\/div><div class=\"bd-prob-card\"><div class=\"bd-prob-num\">03<\/div><h4>Action on neurotransmitters<\/h4><p>Like argireline (acetyl hexapeptide-8), they limit muscle contraction - interesting for dynamic wrinkles. On the forehead, they have difficulty reaching the muscle (separated by a layer of fat); around the eyes, with thin skin and close muscle, they are particularly relevant.<\/p><\/div><div class=\"bd-prob-card\"><div class=\"bd-prob-num\">04<\/div><h4>Growth factors (EGF)<\/h4><p>EGF, naturally present in the skin, stimulates cell growth and collagen, with a real impact on regeneration. Two reservations: composed of 53 amino acids, it doesn't easily penetrate the barrier - and see the caution section below.<\/p><\/div><\/div><\/div><\/section><section class=\"bd-dark\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">Precaution<\/span><h2>EGF: in which cases <em>be careful<\/em> ?<\/h2><p>With growth factors, a precautionary principle should be applied in two situations. Firstly, in the case of redness linked to small vessels (telangiectasias): it's best to avoid a product containing EGF, as it could encourage the formation of new vessels. Secondly, in the case of a history of skin cancer or precancerous lesions: an active ingredient that stimulates cell growth is not ideal in this context.<\/p><div class=\"bd-dark-quote\"><strong>Neither mutagenic nor carcinogenic, but exercise caution<\/strong><p>To be clear, EGF is not mutagenic and does not cause cancer; but as it stimulates cell growth, it could theoretically accelerate an already existing lesion. When in doubt, these situations require medical advice: no EGF product is therefore offered as an over-the-counter product here.<\/p><\/div><\/div><\/section><!-- ===== S\u00c9LECTION PRODUITS ===== --><section class=\"bd-section\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">The selection<\/span><h2>The best <em>peptide serums<\/em><\/h2><p class=\"bd-lead\">Here's a selection of well-formulated peptide serums, with BeautyDecoded scores and user feedback.

Alternation is therefore the best approach.<\/p><p class=\"bd-lead\">It's difficult to quickly assess the anti-aging effect of a peptide serum, which is why it's important to choose carefully. But most of these products have a dual role, anti-aging and moisturizing\/soothing, and in this respect a fairly rapid improvement in radiance is often visible. However, every skin reacts differently. The main drawback of peptides is that scientific proof of their anti-aging action is not yet as solid as for retinol.<\/p><div class=\"bd-video-wrap\"><iframe src=\"https:\/\/www.youtube.com\/embed\/WaT1_mi0Y2Y\" title=\"Peptides explained - BeautyDecoded\" loading=\"lazy\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/div><\/div><\/section><!-- ===== CTA APP (bd-final standard) ===== --><section class=\"bd-final\" style=\"padding-top:48px !important;margin-top:0 !important\"><div class=\"bd-wrap\"><div class=\"bd-final-inner\"><div class=\"bd-section-label\">Further information<\/div><h2>Find the right peptide serum for <em>your skin profile<\/em>.<\/h2><p>The BeautyDecoded application lets you scan any cosmetic product to visualize its suitability for your skin type and needs, based on INCI analysis.<\/p><div class=\"bd-cta-wrap\" style=\"justify-content: center;\"><a href=\"https:\/\/beautydecoded.go.link\/88eZ2\" class=\"bd-cta\" target=\"_blank\" rel=\"noopener\">Discover BeautyDecoded<\/a><\/div><div class=\"bd-cta-meta\" style=\"margin-top: 16px;\">Application available on iOS and Android<\/div><\/div><\/div><\/section><section class=\"bd-section\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">Frequently asked questions<\/span><h2>Your questions about <em>peptides<\/em><\/h2><div class=\"bd-faq-list\"><details class=\"bd-faq-item\"><summary>Are peptides \u00abbotox in a bottle\u00bb?<\/summary><div class=\"bd-faq-answer\">No. Certain peptides acting on neurotransmitters (such as argireline) slightly limit muscle contraction, but their effect is nothing like that of injected botox.
