I have used various products from Swiss Toniq, notably their serums. I love this one, I feel it goes deeper into my skin and nourishes it, while also making it luminous, like the other serums. It is difficult to explain to others how I feel when using Fiona’s products, but the bottom line is that I did not need to buy anything else. My skin is happy and wants more. I gradually gave up even on eye products. I have a dry skin. I don’t know how someone with a different kind type would feel. Thank you for your wonderful products.
