Vichy, best known for its dermatologist-developed skincare and thermal spa water, offers a dedicated claim-your-sample page for UK customers.

Head to the Vichy UK website, enter your details on the samples page and a trial-size product from the current rotation is posted out at no cost.

Vichy also periodically runs sample giveaways of specific lines, such as Dercos anti-dandruff shampoo, through its social media channels, so it is worth following the brand for extra opportunities.
