What it is: A luxurious, fast-firming serum that feels weightless on your skin but makes a powerful, uplifting impact.

Who it's for: All skin types.

What it does: Harnessing potent bio-marine extracts, it hydrates, detoxifies, tightens and smoothes the skin. Spirulina maxima, a high-powered algae extract, boosts collagen growth while helping to tighten and smooth skin from the inside out; maris water, a mineral-dense seawater, detoxifies and exfoliates the skin, helping boost cell turnover and renewal; and green tea extract, a powerful natural antioxidant, helps defy free-radical damage and re-energize skin.

How to use: After toning, dab on skin and gently smooth over your face. Let it absorb before layering under any other treatments. Use daily as part of your cleansing ritual.
