Sorry UK Residents only

Welcome to TheLitmusTest, where you can try free samples of cosmetic and toiletry products in the comfort of your own home. All we ask in return is your honest opinion of their performance.

So how does it work - we ask you to register online as a LitmusTest member, we'll send you free samples to try. You tell us how well they perform by completing an online questionnaire.

Free samples, what’s the catch – no catch, we simply use your responses to inform manufacturers how well their products perform. We are not trying to sell or promote anything. We do not charge to join TheLitmusTest and all samples are free. Your details are confidential and will not be passed to anyone else. The samples have not been tested on animals.

No idea what this is like I have only just joined
