RonaCare® Luremin™: The anti-wrinkle active ingredient

Move over, Retinol! Here's a new way to stimulate cells for naturally youthful skin

Users of skin care cosmetics around the world are turning to retinol-based anti-aging products for their impressive collagen-boosting properties. Too bad this active ingredient can cause flaky, irritated skin - and lose its efficacy after a couple of weeks. Wouldn't it be nice if there were an anti-aging cosmetic active ingredient as reliable and easy on the skin as it is powerful in wrinkle reduction? We at Merck are proud to introduce just that: RonaCare^® Luremin™, the naturally derived, highly stable wrinkle reducer that is both effective and easy to formulate.

Rhubarb to the rescue
RonaCare^® Luremin™ (the active ingredient is dihydroxymethylchromone), is closely related to medicinal rhubarb, the colorful leafy vegetable and flavonoid source well known for its antioxidant and skin-healing properties. This nature-identical molecule can activate certain skin cell genes to stimulate collagen synthesis - and fight off wrinkle factors like collagenase and elastase.

Rhubarb also gives RonaCare^® Luremin™ some key advantages over retinol: RonaCare^® Luremin™ works as an anti-inflammatory and boasts a nearly flawless toxicological profile. That means no skin irritation, no sensitivity, and no product degradation caused by sunlight - making it the smart choice for youth-boosting sun care products.

Stable & reliable
RonaCare^® Luremin™ remains potent regardless of light or air exposure. Put to the test against both retinol and retinol palmitate formulations, it showed dramatic results: while the stability of the retinol-based formulations dropped after just one week, RonaCare^® Luremin™ maintained the same high stability index for a month. So you can formulate reliable anti-wrinkle products with full confidence - and your customers can enjoy their benefits time after time.

RonaCare^® Luremin™: Vibrant skin, stable products. Now that's a "stimulus package" we can all agree on! Would you like further information? Please contact us. We look forward to hearing from you - and working with you.
