The invention relates to the use of para-coumaric acid or para-hydroxycinnamic acid derivatives in cosmetic or dermatological compositions, specifically to the use of at least one compound derived from para-coumaric acid having a general formula (I) below:
in which, especially, Z represents an oxygen or an —NH— group; X and Y are identical and each represent a CH or CH
2
group, as an active principle with depigmenting, free-radical-scavenging and/or antiinflammatory activity.
The invention also relates to the use of the above compounds for cosmetic care or for the preparation of a pharmaceutical composition, especially for depigmenting an area of skin, having antiradical and/or antiinflammatory activity.

The present invention provides new classes of phenol compounds, including those derived from tyrosol and analogues, useful as monomers for preparation of biocompatible polymers, and biocompatible polymers prepared from these monomeric phenol compounds, including novel biodegradable and/or bioresorbable polymers. These biocompatible polymers or polymer compositions with enhanced bioresorbabilty and processibility are useful in a variety of medical applications, such as in medical devices and controlled-release therapeutic formulations. The invention also provides methods for preparing these monomeric phenol compounds and biocompatible polymers.
