In just a few years, peptides have become essential anti-aging allies and have found their way into numerous cosmetic formulations. Whether for protection against external aggressions, their firming or smoothing action, or their relaxing properties, peptides offer a multitude of benefits, propelling them to the rank of star active ingredient of the moment. Discover the superpowers of these fascinating little molecules today!
What is a peptide?
Peptides are made up of a chain of amino acids and form the basis of proteins.
There are a wide variety of them, each with many distinct biological functions:antioxidant, antimicrobial, communication between cells, etc.The function of a peptide is determined by its structure, that is, the order in which the amino acids are attached to each other. In the human body, although there are 20 different amino acids, not all of them are used simultaneously to form peptides. Thus, a dipeptide will be the combination of two amino acids linked by a peptide bond, a tripeptide will consist of three amino acids and two peptide bonds, etc.
Peptides are produced by various cells in the human body. For example:
- L-type enteroendocrine cellsare specialized cells in the digestive tract and are involved in the production of peptides such as peptide YY, which plays a role in regulating appetite and energy.
- Pancreas cells produce insulin, a hormone peptide.
Other cells produce peptides that can act as signals to initiate and stimulate the healing process, while others areinvolved in muscle contractions.
What types of peptides are used in cosmetics?
In skin care, different peptides are used depending on the desired effects on the signs of aging.
Toning, plumping, and firming peptides
This category of peptides regulates skin repair mechanisms and plays a key role in tissue regeneration. They send a message to fibroblasts to stimulate the synthesis of collagen, elastin, and hyaluronic acid. data-mce-fragment="1" style="font-weight: 400;">Certain peptides, such as glutathione, are capable ofneutralizing free radicals to combat oxidative stressresponsible for premature skin aging.
Neurotransmitter-inhibiting peptides
A muscle contracts thanks to communication between a nerve and a muscle, via chemical transporters known as neurotransmitters. Depending on their composition, these peptides instruct the muscle to contract or remain relaxed. In aesthetic medicine, botulinum toxin is used to block muscle contraction and reduce expression lines.
Inhibitory peptidesprecisely reproduce the skin-relaxing effect of botulinum toxin. They block the muscle contraction signal by preventing the release of neurotransmitters.
Peptides in FILORGA anti-aging skincare
Peptides can therefore offer a whole range of benefits to the skin thanks to diverse mechanisms of action. As we've just seen, some have the ability to reduce wrinkles and increase skin firmness thanks to their regenerative properties, while others have a protective role against external aggressions.
To effectively combat the signs of aging, FILORGA Laboratories have concentrated all the effectiveness of peptides at the heart of the formulas in the TIME-FILLER range.
The peptides in TIME-FILLER 5XP cream
To target deep wrinkles,TIME-FILLER 5XP cream contains a synergistic combination of two peptides, a tripeptide and a tetrapeptide, as well as high molecular weight encapsulated hyaluronic acid. These peptides are the result of advances in our understanding of skin repair mechanisms. The healing process involves peptide fragments resulting from the breakdown of dermal proteins such as collagen, elastin and fibronectin. These fragments are true messengers capable of regulating fibroblast activity to regenerate tissue.
The peptides used in TIME-FILLER 5XP cream contain amino acid sequences similar to those of the peptides found in the dermis during regeneration. They act by mimicryby stimulating the synthesis of collagen, elastin, and hyaluronic acid, while ensuring good tolerance.
To correctexpression lines, the cream TIME-FILLER 5XP also includes a relaxing tripeptide to block muscle contraction.
to block muscle contraction.
TIME-FILLER SHOT 5XP peptides
The treatment TIME-FILLER SHOT 5XP reinvents the application of anti-wrinkle treatments. This treatment, inspired by micro-injections of botulinum toxin and intended exclusively for the treatment of expression lines, incorporates a patented peptide complex composed of a hexapeptide and an octapeptide. It also acts on muscle contraction, but in a different way than those contained in TIME-FILLER 5XP cream.
