Every business gets wrinkles eventually, so what do you do about them? That was the question at the heart of a lively Euronews event at VivaTech looking at longevity both in personal and professional life.

The conversation turned personal pretty quickly, with Delphine Viguier, L'Oréal's Chief Innovation and Prospective Officer, joking that "I have much more wrinkles than my business plan".

She said that when the signs of age do show up, either in your skin or in your strategy, the response is the same: change your habits. For her, that means oral supplements, sunscreen, anti-aging products and, for companies, it means boosting innovation, opening up to outside ideas and rediscovering creativity.

For Pauline Adam-Kalfon, Chief Innovation and Impact Officer at PwC France and Maghreb, the prescription for an aging business is direct.

"Reinvention starts with subtraction," she said. Her advice: kill whatever in your business no longer creates differentiated value, rather than just piling up new projects.
