Amino acids/Peptides

Peptides are increasingly used in cosmetic care products, whether designed for the skin or for the hair. Among the most popular peptides is acetyl tetrapeptide-2. But what is its purpose and is it safe to use? Let’s take a closer look.

Certain cosmetic peptides directly target the micro-contractions responsible for expression wrinkles. “Dipeptide Diaminobutyroyl Benzylamide Diacetate” belongs to this family of active ingredients. But how exactly does it work on the skin? Are there any specific hazards or precautions to bear in mind? Continue reading to learn more about “Dipeptide Diaminobutyroyl Benzylamide Diacetate.”

Peptides have become essential active ingredients in treatments targeting the signs of ageing. Among these, Matrixyl 3000, composed of two peptides, "Palmitoyl Tripeptide-1" and "Palmitoyl Tetrapeptide-7", attracts particular interest in cosmetics. But what exactly are "Palmitoyl Tripeptide-1" and "Palmitoyl Tetrapeptide-7"? Let us decipher their roles and mechanisms of action together.

Regarded as the benchmark peptide for reducing expression lines, argireline is an active ingredient frequently found in skincare treatments aimed at slowing skin ageing through its effects on facial muscles. However, while its mode of action is relatively well understood, its production process is less so. Would you like to discover how argireline is synthesised? Continue reading: we explain it all below.

Argireline is a peptide that has become indispensable in skincare targeting early wrinkles. Its reputation rests on a biomimetic mechanism inspired by neuromodulators such as botulinum toxin. However, its efficacy also raises questions about its safety of use. Does argireline pose any risks to the skin? Let’s explore this question together.

Considered a natural alternative to botox, argireline is increasingly incorporated into anti-wrinkle skincare products under its INCI name “Hexapeptide-8”. In which product formulations can argireline be found? Let’s take an overview of the types of products that may contain it.

Argireline is an innovative cosmetic active ingredient that acts on the muscle contractions responsible for wrinkles in a manner similar to botox. Does it also require injection? If not, how can one harness argireline’s benefits? In this article, we provide an overview of how to use argireline.

A unique peptide with effects similar to those of botulinum toxin, argireline is a relatively recent active in skincare. Primarily used to reduce expression lines, it can be combined with other actives to optimise its efficacy. Which active ingredient combinations are most relevant with argireline? Learn more in this article.

The skin around the eye is the thinnest on the face and rapidly reveals signs of fatigue and ageing. Argireline, often regarded as a topical alternative to botox, is sometimes promoted for its smoothing effect on the eye area. However, its impact on under-eye bags remains little understood. Could argireline help to reduce their appearance? Let us examine the evidence together.

To diminish the visible signs of ageing, many individuals turn to botulinum toxin. However, this invasive treatment is not without its drawbacks. It is in this context that argireline, a peptide complex, has established itself in recent years as a natural alternative to botox. What is argireline? Can it genuinely replicate the effects of botox? Are there any contraindications associated with argireline? Here is an overview of the key information about argireline.

Often associated with pregnancy, stretch marks arise from rapid distension of the skin. Once formed, they do not disappear spontaneously, but the use of certain cosmetic formulations can help to reduce their visibility. What about elastin creams? Can they act on stretch marks? Let us explore this together.

Elastin is a key protein responsible for the skin’s suppleness and elasticity. In cosmetic formulations, it is often combined with other active ingredients to enhance its effects. To optimise the benefits of elastin, it is useful to know which combinations to favour. Which active compounds can be paired with elastin? Read on for more information.

While certain cosmetic products aim to stimulate elastin synthesis in the skin, others integrate elastin directly into their formulation. Which products are these? Continue reading to learn more about the various types of treatments in which elastin can be found.

Elastin is no longer confined to the skin’s dermis; it now features in cosmetic products formulated to moisturise or firm the skin. Yet its origin is intriguing: how is the elastin in these treatments obtained? In this article, we explain the various methods used to source elastin for cosmetic use.

Elastin is a protein in the dermis responsible for the skin’s elasticity and resilience. However, its production declines with age, leading to a reduction in firmness and tone. To compensate for this decline, some cosmetic products incorporate elastin into their formulations. But how does it act when applied topically? Let us explore the effects of elastin on the skin.

Long studied for its effects on the skin, elastin is now attracting interest in hair care. Does it provide benefits to hair or scalp health? Find out more in this article.

Between serums, creams and dietary supplements, elastin-based products are proliferating. However, the efficacy of this active compound depends closely on the form selected and the consistency of its application. What are the different ways to integrate elastin into your daily routine? Continue reading to discover our recommendations.

Naturally present in connective tissues, elastin is an essential protein for the skin’s structural integrity, allowing it to regain its shape after each stretch. Yet its production declines over time, contributing to skin laxity. Elastin is also incorporated into certain cosmetic formulations, but this raises several questions. How is it sourced? What are its benefits when applied topically? Does its use demand any special precautions? Read on to learn more about elastin.

L-carnitine is not confined to its applications in nutrition and sport. It is increasingly investigated in dermatology, and some credit it with the ability to strengthen hair anchoring and prevent hair loss. Myth or reality? Find out here whether the scientific literature supports this hypothesis.

Used as a dietary supplement or incorporated into cosmetic formulations, L-carnitine is attracting increasing interest. What are its functions and in which contexts is it employed? Read on to discover everything you need to know about L-carnitine.

Known for its role in fat burning, L-carnitine is increasingly studied for its effects on skin and hair. Whether applied topically, taken orally or administered by injection, its mechanisms of action vary and yield different outcomes. Let us explore together the various methods of using L-carnitine.

Essential for the transport of long-chain fatty acids to the mitochondria, L-carnitine (C₇H₁₅NO₃) is a water-soluble amino acid that has been extensively studied for its roles in energy metabolism. It is now also gaining recognition in the cosmetics field for its multiple skin benefits. Here are the main advantages of L-carnitine that make it a preferred choice in cosmetics.

L-carnitine is a well-known active ingredient in the fields of nutrition and sports, often associated with fat burning. However, its benefits do not stop there: it is also incorporated into cosmetic formulations aimed at improving skin firmness. How does it act on the skin? And can it truly help to firm tissues? Let us decode the role of L-carnitine in combating skin ageing.

Radiant yet often prone to imperfections, oily skin can be a source of discomfort. While several active ingredients can improve its appearance, in recent years attention has focused on L-carnitine. What is this active ingredient? What are its benefits for oily skin? Find out more below.

L-carnitine, an amino acid naturally found in the body, is increasingly used in the cosmetics industry for its various benefits to skin and hair. In which products can it be found? Here you will find the different formats and formulations likely to contain L-carnitine.
