What is biotechnology in cosmetics?
Biotechnology combines biology and technology to create high-performance cosmetic active ingredients from plant sources, using sustainable processes that preserve their natural properties and maximize their effectiveness. Here are the main methods used in HYLÉRIA skincare:
- Fermentation : Microorganisms, such as bacteria or yeasts, transform plant compounds to release active molecules, such as antioxidants. This process improves bioavailability, promoting better absorption through the skin. For example, Leuconostoc/Radish Root Ferment Filtrate , a natural preservative in our products, is derived from the fermentation of radishes.
- Oil-based extraction : An environmentally friendly technique that extracts active oils, such as those from thyme or camelina, without chemical solvents. This process preserves antioxidant and anti-inflammatory properties, as in La Manière Douce 's CLEAR Oléoactif® , which regulates sebum and reduces blemishes.
- Enzymatic synthesis : Enzymes transform plant sugars or lipids to produce moisturizing active ingredients, such as Aquaxyl (Xylitylglucoside, Anhydroxylitol, Xylitol) in La Manière Douce , which deeply moisturizes and strengthens the skin barrier.
- Ecological extraction : Gentle methods, such as distillation or pressing, extract pure active ingredients, such as Opuntia Biocomplex SH (Prickly Pear) or Hamamelis Virginiana Leaf Water , while minimizing environmental impact.
These processes produce natural, pure, and effective active ingredients, while reducing the use of water, energy, and agricultural land. They meet the growing demand for ethical, high-performance, and environmentally friendly cosmetics.
How HYLERA uses biotechnology
HYLÉRIA Paris incorporates biotechnology to concentrate the power of natural active ingredients in the Radiance Duo , offering targeted treatments that hydrate, soothe, and refine the skin. Formulated in small batches, our products combine scientific innovation with artisanal expertise.
The Gentle Way
La Manière Douce is a gentle exfoliant that refines texture, hydrates, and purifies sensitive skin thanks to biotechnological and natural active ingredients.
- CLEAR Oléoactif® : Obtained by Oléo-eco-extraction, this active ingredient combines organic thyme and camelina oil, rich in antioxidants and omega 3 and 6. It reduces inflammation, regulates sebum, and diminishes imperfections.
- Xylitol Complex (Xylitylglucoside, Anhydroxylitol, Xylitol) : Produced by enzymatic synthesis from natural sugars, this active ingredient hydrates by stimulating aquaporins, hyaluronic acid, and ceramides. Result: a true hydration booster.
- Hamamelis Virginiana Leaf Water : Obtained by distillation, this hydrosol soothes redness and tightens pores thanks to its astringent properties, ideal for sensitive skin.
The Art of Portraiture
L'Art du Portrait nourishes, repairs, and soothes sensitive skin, thanks to natural and biotechnological active ingredients.
-
Opuntia Biocomplex SH : Extracted from prickly pear cladodes using ecological methods, this polysaccharide-rich active ingredient forms a moisturizing barrier and promotes healing. Results: significant hydration from the first application and with prolonged treatment (15 to 30 days), smoothing, and protection. Apply morning and evening to clean skin for a radiant complexion.
-
Hamamelis Virginiana Leaf Water : Obtained by distillation, this hydrosol soothes sensitive skin, reduces redness, and tightens pores.
-
Camelina Sativa Seed Oil : Rich in omega 3 and 6, this oil nourishes, reduces inflammation, and promotes regeneration.
