AQUA
Aqua is an essential ingredient for the health and appearance of skin and hair, thanks to its role as a moisturizing base and solvent.



AQUA
EXCIPIENT ⎪ SOLVENT
Aqua forms the fundamental basis of any cosmetic formulation and is much more than just a solvent.
This water purified according to pharmaceutical standards offers numerous benefits for the skin and plays a crucial role in the effectiveness of care.
Its natural moisturizing power and its ability to convey active ingredients make it an essential ingredient for skin health.
Aqua also helps maintain the physiological balance of the skin while ensuring a pleasant texture to cosmetic products.
What is aqua? Definition and origin
Aqua refers to purified water used in cosmetic and pharmaceutical formulations, treated using strict processes to remove any impurities.
This water meets very precise quality criteria, with a controlled mineralization rate and a total absence of microbiological contaminants.
The purification process includes several stages: filtration, reverse osmosis, distillation and sterilization by UV or ozone.
These treatments guarantee water with a purity of 99.9%, complying with European and American standards for the cosmetic industry.
Unlike tap water which contains chlorine, limestone and various substances, aqua cosmetic has a neutral pH stabilized between 6.5 and 7.5.
This neutrality allows optimal compatibility with all skin types, including sensitive and reactive skin.
