Guerlain reveals a unique multi-layer protection : the Skin Shield Technology. Strengthening the skin's natural defences against the harmful effects of UV rays*, this advanced technology protects the skin ""from within"". Like a pearl, the skin is protected, layer after layer.
This exceptionally light and translucent SPF 50+ UV shield is a broad-spectrum sunscreen providing high protection against UV rays. Intensely protected, the skin is bright and luminous in all situations. Apply a dab every morning to the face and neck and leave to penetrate. After use, apply Blanc de Perle Brightening Foundation.
