Peptides, key active ingredients for skin beauty

Peptides belong to the large family of proteins . They result from the assembly of amino acids , small compounds present in nature, both in the animal and plant kingdoms.

In humans, peptides are involved in many natural processes. They are found in different forms with different actions: glutathione in natural antioxidant mechanisms , interleukins and cytokines in the inflammatory reaction , insulin and oxytocin in the hormonal system , or endorphins at the neurological level.

In the skin, cosmetic peptides act by biomimicry: the supply of exogenous peptides restarts the different natural mechanisms induced by the peptides already present in our body; according to different mechanisms:

- Signal peptides : they trigger cascades of reactions, ordering our body to synthesize molecules: collagen and elastin, major components of the dermal matrix in the skin.

- Transporter peptides : they ensure the transport and release of certain molecules such as trace elements (copper or manganese). Thus, peptides ensure the release of copper and manganese, which are essential for the healing and tissue regeneration process .

- Enzyme inhibitor peptides : they prevent the action of enzymes such as those responsible for the degradation of collagen and elastin, while neurotransmitter peptides control muscle contraction through a “botox like” effect by inhibiting the action of neurotransmitters.

Since the 1980s, the cosmetic industry has been studying and drawing inspiration from peptides naturally present in the skin. It is in this biomimetic approach that cosmetic peptides are developed that are capable of restarting our natural cellular mechanisms.

Of natural or synthetic origin, cosmetic peptides have several advantages:

· Perfect affinity with cellular processes : due to their structure, which is identical or very close to that of skin peptides, cosmetic peptides act like endogenous peptides.

· Good bio-assimilation : thanks to their smaller size than proteins, they can pass through the different layers of the skin.

· High tolerance and safety : because, unlike proteins, they do not trigger allergic reactions.

Skin aging results in the appearance of characteristic symptoms : sagging, loss of density, elasticity and suppleness, deepening of wrinkles, appearance of spots, dull complexion. At the molecular level, various phenomena explain the installation of signs of aging:

· Slowing down of cell renewal .

· Degradation and poorer renewal of dermal components (extracellular matrix, collagen and elastin fibers).

· The weakening of antioxidant systems which no longer fight effectively against free radicals and oxidative stress.

· Alteration of sensory receptors in the skin .

While there are an infinite number of peptides in nature and the body, research is progressing to identify the biological actions and benefits of peptides in the skin.

Today, peptides have many properties for skin care such as:

· Anti-aging benefits, for example by promoting the endogenous synthesis of collagen and elastin.

· An action on the radiance and renewal of the skin by stimulating cell proliferation.

· Regulation of melanogenesis involved in the skin pigmentation process.

· Soothing properties (against inflammation).

· Or, protection against oxidative stress induced by free radicals.

Peptides have a huge range of benefits. Radiance, firmness, skin defense, reduction of wrinkles, imperfections and spots... whatever your beauty need, there is a peptide to meet it.

myBlend Research capitalizes on this biomimetic science to naturally relaunch the skin's mechanisms and allow it to express its full potential. myBlend thus seizes the immense and multiple powers of peptides by developing:

• Targeted peptides : such as Peptide Eclat – to even out the complexion – present in particular in Superserum Eclat or Fluide Lumière.
• Neuropeptides : such as Renocten – to protect the cutaneous sensory receptors essential for cellular communication – present in our Essential range (Regenerating Cream and Fluid , Revitalizing Eye Concentrate ).
• Regenerating peptides : such as Imureline – to stimulate cell regeneration – present in the Firming Superserum .

myBlend pushes the boundaries of science and develops [Peptide-complex]4P - an innovation that reveals the synergistic power of a combination of expert anti-aging peptides, to be discovered in our Essential Peptides treatments .

Years of research and several scientific publications* in collaboration with Clarins Laboratories and Professor Misery have made it possible to develop: [Peptides-complex]4P.

Inspired by regenerative medicine in skin longevity, our experts' advanced research has drawn on the powers of peptides to put this complex. A unique combination of 4 peptides with unmatched regenerative power to protect and stimulate skin sensory receptors , the key to activating longevity with pure and very high quality molecules.

Through their biomimetic actions in the skin, peptides have the broadest spectrum of cosmetic actions. They restart the skin's natural mechanisms slowed down by our lifestyle and natural aging.

Together, they combine 4 targeted biological actions for anti-aging effectiveness at the source :

1. Protection of skin sensory receptors against stress and free radicals
2. Restarting cellular communication to reactivate the key mechanisms of cell functioning (collagen, elastin, hyaluronic acid, oxygenation, etc.)
3. Stimulation of cell renewal and regeneration
4. Maintaining natural defenses for strong skin

In the Regenerating Cream, the Revitalizing Emulsion, the Revitalizing Rich Cream, the [Peptides-complex]4P is associated with afermented turmeric extract (antioxidant action), a duo of hyaluronic acids (deep hydration) and the marine prebiome (preserves the microbiota). A global action on all the needs of the skin: the skin is smooth and firmer, wrinkles and fine lines visibly reduced, all hydrated 24 hours.

In the Revitalizing Eye Concentrate, the action of [Peptides-complex]4P is combined with the anti-puffiness and anti-dark circle benefits of horse chestnut escin and the smoothing power of organic oat sugars for a lifted eye contour and a refreshed look.
