‘Eternal Beauty’ - The Beauty Inside. Klavuu strives to follow the beautiful and eloquent value the pearl holds. They developed the term "pearlsation", Klavuu’s own identity and character of turning over your skin to a completely new spectrum. All of Klavuu’s products contain only the highest grade Korean pearl on all of their products, marked as pearl extract on the label. Pearl has been known for its anti-aging function, due to the minerals and active ingredients in them that keep the skin a little acidic, preventing the aging process while keeping the moisture locked in.
