The present invention concerns a method to prepare a filler with a hyaluronic acid, which has improved properties of chemical-physical stability over time and optimal viscosity for cutaneous injection. In particular the method comprises a first step in which the hyaluronic acid is crosslinked, and a subsequent step for the neutralization and hydration of the crosslinked hyaluronic acid.

The present invention provides a topical composition comprising extract from Coriolus versicolor for use for preventing and/or treating by vaginal or cervical administration of a vaginal or cervical disorder which is caused by an infectious agent, in particular, human papiloma virus infections and related disorders, including cervical cancer. The composition of the invention acts enhancing genital immunity against infectious agents and re-epithelising damaged tissue.
