SK-II (pronounced ‘ess-kay-two’) has been a household name in Asian skincare since the 1980s with its iconic Facial Treatment Essence. After all, it’s been given the nickname ‘miracle water’ because of how well it works for skin - and trust me, ‘miracle’ isn’t an adjective that should be thrown around lightly when it comes to skincare! SK-II`s Japanese facial treatment products are part of a healthy skin care routine.
