Fabric masks are emerging as the new trendy product in the cosmetics industry. Unavoidable in Asia, democratized in Europe and the United States by Sephora, L'Oréal, Dr Jart+ or Estée Lauder, they are seducing more and more consumers every day.
More and more brands are now turning to bio cellulose to manufacture their masks: a material derived from biotechnology, but which remains a living material, difficult to control and which has already given rise to a few scandals concerning these manufacturing methods. In particular, problems of mould, due to the non-respect of hygiene and packaging rules.
At the forefront of the mask market in Europe and anxious to offer the best quality to its customers, Lessonia has audited the main manufacturers of bio cellulose on the market. This, with the constant objective of controlling the entire production chain.

Result of the audit:
Among the many manufacturers of bio cellulose masks in Malaysia, Vietnam or Indonesia, it is clear that not all are able to meet the quality, hygiene and traceability requirements of the cosmetic industry. Bio-cellulose is sometimes produced in a "home-made" way, which could unsurprisingly explain the causes of mold found in some masks. Fortunately, others are doing well by displaying impeccable quality and manufacturing conditions.
Lessonia has contracted with 2 of these manufacturers, including the supplier of the biggest Korean cosmetic brands, and can commit to the quality of its products.
The company offers 2 types of bio cellulose for the manufacture of face masks:
- Bio cellulose wet: treatment without preservatives or gamma rays.
- Bio dry cellulose: brings the maximum security and allows to impregnate more actives.

What is bio cellulose: a natural and biodegradable 100% material, made of ultrafine cellulose fibers, produced by microorganisms during the fermentation of the coconut juice from which it is produced.

A precursor in the field of mechanobiology since 2007, Coheliss is a firming, anti-gravity active ingredient developed by Silab to stimulate the skin's mechanical and biological cellular functions, in response to mechano-stress. It acts specifically on sagging skin, a major concern for consumers.
Additional efficacy data in vitro in 2016 confirm its ability to act on mechanobiology, a central process in maintaining skin firmness, by stimulating its three pillars: mechano-sensation, mechano-transduction and mechano-response.
Its firming action has been demonstrated with the help of modelling in vivo developed to measure skin response, with or without mechanical stress, in key areas of the face. After 28 days of twice-daily applications, and compared to placebo, the ingredient dosed at 3% improved skin's ability to return to its initial state by 12.6%. At 4%, skin tone increased significantly by 19% (p < 0.05) and skin tension by 16% (p < 0.05).
Through its smoothing and anti-wrinkle effect, Coheliss limits the appearance of gravitational folds and expression lines. The total surface area of wrinkles in crow's feet and the nasolabial fold was reduced by 15% and 26% respectively (p < 0.01) (Results after 56 days of twice-daily application, compared with placebo).
A combination of firmness and anti-gravity, Coheliss is positioned as a biomimetic active ingredient by transposing to the skin the natural properties of arabinoxylans, the molecules responsible for rye's cohesion and mechanical strength.
