It is easily absorbed, has a pleasant scent. I only use it 2-3 times a week as it makes my skin break out if I use it every day. It is rather expensive but I always wait for deals. It does last long though Review: Reduced my turkey neck significantly - Was seriously looking at getting a lower facelift as looking at my neck and the "waddle" that comes with age was depressing the hell out of me. My aesthetics nurse recommended this and I've never looked back. I'm never going to look 25 again but skin is firmer and glows. Would recommend for ladies of a certain age. Not cheap and bottle last only about 5 weeks but cheaper than a face lift ## Features - INSTANT SKIN YOUTHFULNESS - 14% Stabilised Vitamin C (tetrahexyldecyl ascorbate), boosted with optimised red ginseng for skin-brightening and youth-boosting power. - DARK SPOT REDUCTION - Delivers powerful action on the appearance of dark spots. - TOTAL SKIN NOURISHMENT - Enhanced with squalane and vitamin F for deep moisturisation and skin barrier support. - HOW TO USE - Step 1: After cleansing in the morning, massage 6 drops of C-Tetra Luxe across the face, neck and décolletage.
