Each of the 200ml bottles - which are rolling out now at Asda, Tesco and Sainsbury outlets as well as independent chemists - comes in a pastel colour, and has a new longer, narrower shape and a flip-top lid designed for easier application.
All contain Pro-vitamin B5 and vitamin E, together with an extra ingredient for their target nails.
The purple Regular variant, which is suitable for all nail types, contains apricot extract, said to boost moisture, reduce brittleness and build healthier-looking nails.
The Strengthening option is pink and targets those with soft, thin nails and contains hydrolysed wheat protein. Dry brittle nails are the target for the green Moisturising variety with aloe vera which claims nutritive and moisturising properties. Blue Acetone Free with camomile is aimed at artificial and sensitive nails.
