Spa Collection Rather than using mineral oil as a base, Chamonix® skin care products use a proprietary base of calendula flower extract, which has been used for thousands of years in natural healing. It delivers more of the antioxidants and other beneficial active skin care ingredients into the skin without any harmful effects. And, rather than using pharmaceutical preservatives, we import a natural preservative from France comprised of amino acids. It doesn’t clog pores or cause allergic reactions, and there is no oily residue.
