Firm up your skin's future! Featuring a world-first Opal Skin Algae Complex and powerful marine algae, Pro-Collagen Future Restore Serum targets visible signs of collagen decline with every drop. The proprietary Opal Skin Algae Complex comprises a trio of marine microalgae diatoms, featuring an Elemis exclusive diatom discovery, encapsulated within an intelligent delivery system. Diatoms, also known as microscopic algae, are called "opals of the sea" due to their luminosity and can help promote the production of key proteins needed for collagen and elastin in skin. Skin is left looking bouncier, more sculpted and radiant.
