 The last Cadillac item that I'm going to talk about in SwissLine is the Foss Vital Serum. So this is a serum, it's not a booster, it's a serum. It is, like I said, it's a Cadillac of serums in SwissLine. The reason why I really like the serum is because it is perfect for someone that's dehydrated, someone that's dry, and even if you have normal skin types, this is a powerful antioxidant serum. It is made with 24 nutrients, vitamins, and plant extracts from the Swiss Alps. So this is the serum in SwissLine that will be your antioxidant serum. It is great for almost any skin type, like I said, dehydrated, dry, and normal. If you have a skin that's more on the reactive side, you might want to look at the essential serum and the peace booster, but like I said, this is a really nice serum. It fights off free radicals again because of all the packed antioxidant ingredients that there are in there. And so silky on the skin, it's a lovely serum. If you're looking for a serum, definitely check it out. All the links are below.
