Alpine Silk Lanolin and Collagen is made from lanolin, the oil extracted from sheep's wool. Lanolin is one of nature's premium moisturising agents. Modern technology has enabled soluble collagen to be also included in this lanolin creme. Collagen fibres provide a strong network that assist in providing firmness to the skin. Both the collagen and the lanolin used in this product ensure that the creme has high moisture retention properties.
