This review is all about NAILS! I was never much of a nail-person/junkie but lately my beauty horizon has found another addictive element. This addiction is thanks to SEPHORA FORMULA X & ESSIE (will be reviewing in a follow-up post) . The Formula 'X' range is divided into many categories- 'the system', 'classics', 'neutrals', 'metallics', 'topcoat effects', 'translucents', 'shifters', 'sparkles', 'brilliants'...the list goes on, you get the point.
