The 24-year-old singer tweeted her love for Skin Chemist's Wrinkle Killer Snake Serum, a 135-pound potion that includes syn-ake - a neuro-peptide that mimics the effect of the Asian temple viper's venom, the Daily Mail reported.
Syn-ake, which has also been called 'Botox in a bottle,' temporarily freezes wrinkles - preventing them from getting any deeper.
In addition to syn-ake, it also contains oxygen, believed to have a smoothing and plumping effect on the skin.
Tulisa, who is dating footballer Danny Simpson, also uses the brand's fat busting 'Sculpt and Tone' body cream.
And she is not the only A-lister to use snake venom in a bid to stay youthful, Dolce and Gabbana designer, Stefano Gabbana, and TOWIE star Amy Childs are both reported to use the wrinkle buster cream.
