SK-II’s essence is a fabulous skin conditioner that has no scent and feels like water. It gives you added hydration, and it’s a great base before your serums. A couple of drops go a long way, and although it’s an expensive product, it lasts for a long time. I noticed a lot of women in Asia use SK-II, and I’ve always followed a lot of Asian actors so I wanted to see if it would work for me. Of course, it worked beautifully, and I felt like it was worth the investment. Essence isn’t a mandatory product, but my one bottle has lasted me over three months
