Thanks to lobbying from the London Fire Brigade, common kinds of moisturiser present in many homes will now be labelled as a "fire hazard".
A study conducted earlier this year, found that 10 people in the last three years died in fires where highly flammable skin care products were "a contributory factor in the spread and growth" of a fire.
A campaign recommended a warning be added to packaging about the danger of smoking if you use the product.
This is because many common emollient skin products, which are often used by elderly people or those with mobility issues, contain ingredients such as paraffin or petroleum that are highly flammable.
The creams also help with conditions like eczema and are used to prevent bed sores.
Assistant Commissioner Dan Daly said: “This announcement will help spread awareness of the risk and make it easier for people to check the products they are using.
"As well as clear labeling in order to ensure no more lives are put at risk, we urgently need carers, nurses [and staff at] care homes to be educated and trained about the very real risk these creams pose.
"The creams soak into bedding and bed clothes and a dropped cigarette can be enough to set a person and their bedding alight with the fire spreading very quickly."
Products featuring the flammable ingredients include E45, Cetraben and Vaseline.
For those who need to use such products and for their carers, the fire brigade recommends quitting smoking or switching to e-cigarettes.
It also advises that bed linen is regularly washed on a hot cycle to prevent the build-up of the product in the material and using fire retardant bedding and night clothes.
Those who are worried can also organise a home fire safety visit from their local team of firefighters for more advice.
