Guerlain L'Essentiel High Perfection Foundation is made with 97% naturally-derived ingredients with a natural matte finish and high coverage that lasts for 24 hours. The O4N colour is for a medium to deep skin with neutral undertones. With Guerlain L'Essentiel High Perfection, bare skin is more beautiful, day after day. The formula lets skin breathe while preserving its natural hydration and protecting it from daily external aggressors such as UVA and UVB. The complexion is more even, the appearance of imperfections can be reduced and pores and imperfections are blurred.

The ingredients are simple and natural, to create a foundation that respects the skins' equilibrium, whilst delivering impeccable coverage. Beauty-boosting ingredients (including white cocoa bean extract as well as probiotic derivatives and prebiotics): maintain the skin's natural balance, strengthen the cutaneous barrier, and boost hydration.

How To apply Guerlain L'Essentiel Foundation:

Activate: To awaken the complexion, pat the skin with the L'Essentiel brush before applying make-up. Start at the inner corner of the eye, go to the ear, and then down towards the chin.

Prepare: Use L'Essentiel Pore Minimizer Shine-Control Primer to mattify and even out your complexion.

Place two drops on your fingertips and gently warm up the formula between your fingers. Apply to your face and massage lightly into skin, starting at the centre of your face and working outwards. Perform the "Piano Touch" technique to awaken and energise skin – by gently tapping with your fingertips across the face.

Unify: Apply the foundation directly to the L’Essentiel brush.

Then dab the foundation onto the face at five points: forehead, nose, chin, left and right cheeks.

Pat and blend the foundation from the centre of the face outwards until the result is even.

Enhance: Add a finishing touch to face make-up with Terracotta Matte to warm up and sculpt the complexion for a shine-free effect.
