GUINOT does not send out samples. But you can test our products by going to a salon which is an authorised agent for GUINOT products.
A beauty therapist will provide you with specific advice and will give you samples which are best-suited to your skin.
The active ingredients used in our formulations are chosen so as to respect the environment, since Guinot is conscious of its fragility and is concerned about its protection.
Thus, our products are not tested on animals.
