It promotes the growth of beneficial commensal micro-organisms, contributing to ecosystem stability, reinforcement of the skin barrier and improved skin tolerance.

Bakuchiol

A plant-derived molecule extracted from the seeds of Psoralea corylifolia.

Scientific data indicate that it acts on biological pathways similar to retinol, particularly in regulating keratinisation and cellular renewal, without inducing the irritation commonly associated with retinoids.

It also exhibits anti-inflammatory, antibacterial and sebum-regulating properties, making it suitable for sensitive and acne-prone skin.

Chlorella Vulgaris Extract

A microalgae rich in essential nutrients.

It supports skin protective mechanisms and contributes to overall skin vitality.

Comedogenic / Non-Comedogenic

A designation indicating the ability of an ingredient or formulation to clog pores.

A non-comedogenic product is formulated to limit the risk of comedone formation, an essential criterion for acne-prone skin.

Comedone

A skin lesion resulting from obstruction of a pilosebaceous follicle by excess sebum and corneous cells.

It may be open (open comedone) or closed (microcyst) and represents a key stage in the development of imperfections.

Corneometry

An instrumental method used to measure hydration levels of the stratum corneum.

It is based on skin electrical capacitance measurement and is a reference technique in clinical evaluation of moisturising efficacy.

Cranberry Extract

A natural source of antioxidant polyphenols.

It helps neutralise free radicals and limit cutaneous oxidative stress.

Cutaneous Ecosystem

The set of interactions between skin cells, microbiome, lipids and environmental factors.

Its balance is essential for maintaining healthy, functional and resilient skin.

Cutaneous Homeostasis

The skin’s ability to maintain a stable physiological balance despite environmental variations (temperature, humidity, pollution, stress).

It relies on coordinated interactions between the skin barrier, microbiome, immune mechanisms and cellular renewal processes.

ExoPolySaccharide Marine V2

A polysaccharide derived from marine micro-organisms.

It contributes to hydration, protection against pollution and reinforcement of the skin barrier.

Fermentation

A biological process using micro-organisms to transform raw materials.

It improves bioavailability, tolerance and sometimes the efficacy of cosmetic actives.

Glycerin

A reference humectant naturally present in the skin.

It attracts and retains water within the stratum corneum, helping maintain hydration and skin suppleness.

Glycation

A non-enzymatic biochemical process in which sugars bind to skin proteins (notably collagen and elastin), forming advanced glycation end products (AGEs).

This process alters the structure and function of dermal support fibres, contributing to premature skin ageing, loss of firmness and reduced elasticity.

Green / Botanical Biotechnology

A set of scientific processes using plant cells or micro-organisms cultured under controlled conditions.

This approach enables sustainable, traceable and reproducible production of high-purity cosmetic actives while minimising environmental impact.

Hyaluronic Acid – Low Molecular Weight

Hyaluronic acid is a glycosaminoglycan naturally present in the skin, involved in water retention and the structure of the extracellular matrix.

Its low molecular weight form facilitates diffusion into the superficial layers of the epidermis, acting as a humectant to improve hydration, elasticity and barrier support.

INCI

International Nomenclature of Cosmetic Ingredients, standardised list of ingredients in a product.

Active ingredient

Substance responsible for the main action of a skincare product (moisturising, anti-ageing, soothing, etc.).

Keratinisation

The biological differentiation process of keratinocytes as they migrate from the basal layer to the stratum corneum while producing keratin.

Balanced keratinisation is essential for proper barrier function; dysregulation may lead to roughness, comedones or excessive desquamation.

Lactic Acid

An alpha-hydroxy acid (AHA) naturally present in the Natural Moisturising Factor (NMF).

It promotes gentle exfoliation, improves skin texture and supports physiological pH while maintaining hydration.

Lipids
