NARS recently launched a 10-product ‘skin’ collection and I decided to take the Optimal Brightening Concentrate for a quick test drive. 
When it comes to serums, I find that one sees results fairly immediately. This concentrate is a serum that doubles as an illuminator, so it’s to be used in the daytime, under your regular moisturiser. Its pearly Light Reflecting Complex does really brighten, especially when hit with intense sunlight. Its texture is comparable to Estee Lauder’s ‘Idealist’ (which I’m also a big fan of), and it really leaves the complexion more even and your skin feeling silky smooth. And those are just the short-term results.
This line looks very promising. Have you tried NARSskin?
