The secret behind the tailor-made color of Guerlain's Ecrin 4 Couleurs is a four shades eyeshadow palette that can be layered at will. Each tone has just the right texture to enhance colour without altering it: matte, iridescent, satiny or metallic. The eyeshadows glide over the eyelid, dressing it in a wash of long-lasting colour: harmonies to dare using colour as an accessory, others to structure the eyes by playing with light and dark effects. Ecrin 4 Couleurs is available in must-have colour harmonies that are as surprising as they are embellishing. Application: Application is simple and playful, making everything possible for a mistake-proof result. Apply the lightest matte shade as a base, then the iridescent light shade to add a touch of colour, for instance in the inner corner of the eye. To structure the eyes, apply the darker medium shade on your crease. Finally, use the darkest shade as an eyeliner.
