Antiseptics (preservatives) may be harmful to mothers and children.
Using antiseptics (preservatives) is common and the easiest way to prevent cosmetics from spoiling. However, since the exact toxicity is unknown, we could not add this chemical into our products that mothers and children use.
So, our researchers at Lyanature studied and researched a
method of inhibiting the growth of microorganisms using ‘Available Water Activity Index’ - which is widely used in measuring the water in a food. We have implemented this and successfully came up with a satisfying result that prevents cosmetics from altering which is to add water but control the mixing components to lower the available water activity.
This method of preserving the content - without adding any chemical components - and creating an environment that inhibits the growth of microorganisms and preventing cosmetics from altering is probably the world’s very first.
Expiration date is 3 years, even if it has no preservatives.
Lyanature products’ expiration date is equal to that of general cosmetic products.
