Benefit Cosmetics periodically gives away free sachet samples of its best-selling mascaras, letting you try the formula before buying full size.

When the offer is running, simply enter your email address on Benefit’s claim page to have a free sample sent out – stock is limited and offered on a first come, first served basis, so it is worth acting quickly.

Alternatively, you can visit any Benefit Boutique or counter in the UK and ask staff for a free sample of one of their award-winning mascaras in person.
