Boots facial spray that costs 3.99 pounds, is part of the Boots Expert Range, and claims to be "specially formulated to refresh and hydrate".
But a closer examination of the product has revealed that this ‘specially formulated’ facial spray is made from just one ingredient – water.
Shoppers who examined the contents on the side of the Expert Sensitive Refreshing Facial Spritz have found it contains only "aqua".
The facial spray is described as "the definitive answer to those everyday health and beauty problems we all suffer from, but keep putting off".
"Hypoallergenic and fragrance free, it instantly cools and freshens skin, helping to protect it from the drying effects of central heating and air conditioning,” the description reads.
But, the consumer group Which? has warned customers to make sure they were getting value for money.
"Customers should not get carried away by the promises made by products. Always check the ingredients to ensure you are getting what you think you are paying for,” the Daily Mail quoted a spokesman for Which? as saying.
Boots admits that the spray is 100 per cent water but claimed it was justified in calling the spray "specially formulated''.
"The ingredient contained in Boots Expert Sensitive Refreshing Facial Spritz is water. This is clearly stated on the packaging as 'aqua'. This is the case with most facial spritzes, as the benefit is derived from applying a fine mist of water and allowing it to evaporate quickly to refresh and invigorate the skin,” a company spokeswoman said.
