Merck: A trio of marine skincare ingredients to boost skin renewal

Presented at the latest in-cosmetics Asia trade show, that took place in Bangkok, Thailand, from November 1-3, 2022, Merck’s new cosmetic active RonaCare JouvaMer and RonaCare ReviMer, have been designed to boost skin vitality and to be used within a wide range of topical products, from daily skin care to dermocosmetics. The products were recently launched in Europe, the Middle East and Africa.

Extracted from brown seaweed

The two products have been developed from brown seaweed endemic to the Breton coast in France.

RonaCare JouvaMer [1], an extract of Pelvetia canaliculata brown algae, is an anti- aging booster that reduces wrinkles by stimulating collagen synthesis. Additionally, it protects and supports the extracellular matrix for denser, smoother skin.

RonaCare ReviMer [2], an extract of Fucus serratus brown algae, shows preventive anti-pollution effects while enhancing the skin’s biomechanical properties. It also protects hyaluronic acid that helps provide firmer, more elastic skin, and reduces wrinkles.

Marine trio

Complementing the already launched RonaCare RenouMer [3], the new ingredients form a marine trio that offers potent solutions for skin renewal.

Indeed, according to Merck, RonaCare RenouMer, an extract of Polysiphonia elongata red algae, is highly effective in replenishing skin and counteracting the signs of aging. This skin moisture booster strongly increases skin’s moisture levels, promotes collagen build-up and its protection from degradation, which results in a re-densifying effect for visibly smoother, less wrinkled skin.

Sustainable resources

“Algae have been used for centuries as very nutritious food ingredients because of their important minerals and vitamins for the body,” explained Carsten Plueg, Head of Innovation and Application within the Surface Solutions business unit of Merck. “Today, also the cosmetic industry is using those algae substances and the benefits they have on human skin. These marine actives are indeed particularly attractive for consumers as they combine the desire for naturalness and sustainability with proven efficacy in boosting well-aging and skin vitality.”

According to Merck, all three products are efficacy proven and meet the current requirements of sustainability, traceability, and respect for biodiversity. Merck has established mutually agreed terms with France to financially contribute to and collaborate with the regional Fisheries and Aquaculture Committee of Brittany (CRPMEM) as part of the Nagoya protocol.

RonaCare JouvaMer, RonaCare ReviMer and RonaCare RenouMer are Halal certified and vegan. They also fulfill the COSMOS-standard, which defines the requirements for organic and/or natural cosmetics.
