Peptides are portions of proteins, which are long (or sometimes short) chains of amino acids. In the body, peptides regulate the activity of many systems by interacting with target cells. Enzymatic action breaks proteins into peptides so they can exert their influence on the body. Some peptides have hormonal activity, others have immune activity, some are cell-communicating ingredients that tell cells how to react and what to do, some are believed to play a role in wound healing, and still others are believed to affect the pathology of skin conditions such as atopic dermatitis and eczema.
All peptides function as “messengers” and in skin care they have cell-communicating ability, assuming the formulation supports the type of peptide used and is packaged to protect it from degrading. For these specialized peptides to exert a benefit beyond that of a water-binding agent, three criteria must be met: the peptides must be stable in their base formula, they must be paired with a carrier that enhances absorption into the skin, and they must be able to reach their target cell groups without breaking down.
Peptides play a variey of important roles in the body, depending on the type. They may reduce inflammation, enhance antioxidant defense mechanisms, regulate bodily functions and even offer analgesic properties. In cosmeceuticals, three types of peptides are used, including:
•Signal peptides that encourage fibroblasts to increase production of collagen while decreasing the breakdown of existing collagen.
•Neurotransmitter peptides that limit muscle contraction and, thus, are said to mimic the effects of botulinum toxin, smoothing fine lines.
•Carrier peptides that stabilize and deliver trace elements necessary for wound-healing and enzymatic processes.
Known for effective and unique ingredients, SIRCUIT® specializes in a wide array of brand new peptide technologies’, including:
•Purisoft® - A peptide that purifies and protects the skin from pollution.
•Copper Tripeptide-1 - Helps promote collagen and elastin production; helps skin to be firm, smooth, and soft.
•Matrixyl® Synthe’ 6™ (Palmitoyl Tripeptide-38) - A powerful peptide that boosts 6 skin building essentials; delivering skin smoothing, line filling results.
•Leuphasyl® (Pentapeptide-18) - A neuropeptide that gives Botox®-like results. It works synergistically with Argirilene® to reduce the depth of wrinkles caused by the muscle contractions of facial expressions.
•Argirilene® (Acetyl Hexapeptide-8) - Resembles the effects of Botox; when applied to the skin, it relaxes facial tension leading to the reduction of facial lines and wrinkles.
•ChroNOline™ (Caprooyl Tetrapeptide-3) - Peptide derived from Growth Factor derivatives, clinically proven to reduce wrinkles by 29% in 28 days; helps stimulate the production of collagen, laminin, and fibronectin in the Dermal Epidermal Junction to maintain skin’s youthful firmness.
•Inyline™ (Acetyl Hexapeptide-30) - Minimizes expression wrinkles by 14.9% after 28 days; smoothes skin surface.
•Maxi-Lip™ - Peptide that works to stimulate collagen synthesis and
hyaluronic acid production; increases volume in the lip area.
