L’Essentiel, the foundation reinvented by Guerlain. Beauty demands no compromise. Because you should not have to choose between what you want and what you need, Guerlain Research has created L’Essentiel, which combines:
Performance & Naturalness
Make Up & Care
Perfection & Respect
Instant & Durable

Perfectly sealed in pure objects of desire designed by Mathieu Lehanneur, inspired by the subtle art of balance.
