Peptides: Key Actives for Skin Beauty

In just a few years, peptides have become indispensable for their skin benefits. Naturally present in our bodies, these protein fragments composed of amino acids are involved in numerous biological mechanisms. Studied since the early 20th century, biological peptides now inspire science to develop powerful biomimetic actives capable of reactivating the skin’s natural mechanisms. Here’s everything you need to know about peptides.

What Are Peptides?

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

In humans, peptides are involved in many natural processes. They appear in various forms with different actions: glutathione in natural antioxidant mechanisms, interleukins and cytokines in the inflammatory response, insulin and oxytocin in the hormonal system, and endorphins in the neurological system.

How Do Peptides Work in the Skin?

In the skin, cosmetic peptides act through biomimicry: the introduction of exogenous peptides reactivates the various natural mechanisms induced by the peptides already present in our body through different mechanisms:

• Signal peptides: They trigger cascades of reactions, instructing our body to synthesize molecules such as collagen and elastin, major components of the dermal matrix in the skin.
• Carrier peptides: They ensure the transport and release of certain molecules like trace elements (copper or manganese). Thus, peptides facilitate the release of copper and manganese essential for the healing and regeneration of tissues.
• Enzyme inhibitor peptides: They prevent the action of enzymes like those responsible for the degradation of collagen and elastin, while neurotransmitter peptides control muscle contraction with a “botox-like” effect by inhibiting neurotransmitter action.

Peptides: Bio-Inspired Actives

Since the 1980s, the cosmetic industry has studied and been inspired by peptides naturally present in the skin. This biomimetic approach has led to the development of cosmetic peptides capable of reactivating our natural cellular mechanisms.

Natural or synthetic, cosmetic peptides offer several advantages:

• Perfect affinity with cellular processes: Due to their structure being identical or very similar to that of skin peptides, cosmetic peptides act like endogenous peptides.
• Good bioassimilation: Their smaller size compared to proteins allows them to penetrate the different layers of the skin.
• High tolerance and safety: Unlike proteins, they do not trigger allergic reactions.

Peptides: Solutions for Preserving Skin Youth

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

• Slowing of cell renewal.
• Degradation and poorer renewal of dermal components (extracellular matrix, collagen, and elastin fibers).
• Weakening of antioxidant systems that no longer effectively combat free radicals and oxidative stress.
• Alteration of the skin’s sensory receptors.

Although there are countless peptides in nature and the body, research is progressing in identifying the biological actions and benefits of peptides in the skin.

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

• Anti-aging benefits, by promoting the endogenous synthesis of collagen and elastin.
• Enhancing skin radiance and renewal by stimulating cell proliferation.
• Regulating melanogenesis involved in the skin pigmentation process.
• Soothing properties (against inflammation).
• Protection against oxidative stress induced by free radicals.

Peptides offer a vast range of benefits. Radiance, firmness, skin defense, reduction of wrinkles, imperfections, and spots… whatever your beauty need, there’s a peptide to address it.

myBlend Expertise

myBlend Research leverages this biomimetic science to naturally reactivate the skin’s mechanisms and allow it to express its full potential. myBlend harnesses the immense and varied powers of peptides by developing:

• Targeted peptides: such as the Radiance Peptide – to even out the complexion – found in the Superserum Radiance or Glow Fluid.
• Neuropeptides: such as Renocten – to protect essential cutaneous sensory receptors for cellular communication – found in our Essential range (Revitalizing Cream and Revitalizing Emulsion, Revitalizing Eye Care Concentrate).
• Regenerating peptides: such as Imureline – to stimulate cellular regeneration – found in the Superserum Firmness.

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

[Peptides-complex]4P: A myBlend Innovation to Reveal the Skin’s Highest Potential

Years of research and several scientific publications* in collaboration with Clarins Laboratories and Professor Misery have led to the development of the [Peptides-complex]4P.

Inspired by regenerative medicine in skin longevity, our experts’ advanced research has harnessed the power of peptides to create this complex. A unique combination of 4 peptides with unparalleled regenerative power to protect and stimulate cutaneous sensory receptors, key to longevity activation with pure, high-quality molecules.

Through their biomimetic actions in the skin, peptides possess the widest range of cosmetic actions. They reactivate the skin’s natural mechanisms slowed by our lifestyle and natural aging.

Together, they combine 4 targeted biological actions for source anti-aging efficacy:

• Protection of cutaneous sensory receptors against stress and free radicals.
• Reactivation of cellular communication to reinitiate key cellular functions (collagen, elastin, hyaluronic acid, oxygenation…).
• Stimulation of cell renewal and regeneration.
• Maintenance of natural defenses for strong skin.

The [Peptides-complex]4P in myBlend Treatments

In the Regenerating Cream, Regenerating Fluid, and Rich Regenerating Cream, the [Peptides-complex]4P is combined with fermented turmeric extract (antioxidant action), a duo of hyaluronic acids (deep hydration), and marine prebiome (preserves the microbiome). This comprehensive action meets all the skin’s needs: the skin is smooth and firmer, wrinkles and fine lines visibly reduced, all while being hydrated for 24 hours.

In the Revitalizing Eye Concentrate, the action of the [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 refreshed look.
