While a product's packaging may tell you exactly what the cream, gel or serum contains, have you ever thought about whether the ingredients can penetrate deep enough into your skin to give you the desired results? Nanotechnology can ease your worries on this matter. It is a method that compresses molecules in the beauty products to ensure that the desired ingredients can be delivered directly to the cellular level, and nanotechnology skincare products are suitable for all skin types. Used mostly in serums and moisturisers, companies can choose which substances to compress. 'Not all ingredients in skincare products are beneficial to the deeper/cellular layer of your skin, and thus companies can now choose which substances to use the nanotechnology on to give users the best results,' says Harvey Tsao, training manager of Chantecaille, a makeup, skincare and fragrance company. With the Nano Gold Energizing Eye Cream (HK$2,600, below left) and Nano Gold Energizing Cream (HK$ 4,200, left), for example, Tsao explains that only the gold and silk protein are compressed in the product because they are the only ingredients that are beneficial to the skin at a cellular level. Nanotechnology is now a trend worldwide among skincare companies. But according to Tsao, this technology has been around for years. Another product that also uses nanotechnology is Euoko's Y41 Eye Contour Nanolift (HK$2,840, below). Using 14 new technologies that include millions of nanoparticles, the Eye Contour Nanolift aims to cure all eye area concerns - deep lines, wrinkles, under-eye darkness, dehydration, skin volume and surface smoothness - all in one go. The Chantecaille products can be found at Lane Crawford, Seibu and JOYCE beauty, and Euoko's product can be found at Lane Crawford only.
