Science & Benefits
Porphyridium Cruentum is a red microalgae that secretes a massive amount of sulfated polysaccharides to protect itself from drying out. These polysaccharides are clinically proven to improve skin elasticity and reduce the appearance of fine lines by maintaining a high hydration level in the stratum corneum. For acne-prone individuals, it provides a 'firming' effect that helps keep pore walls structurally sound, preventing the sagging that leads to congestion. While its marine mineral content results in a minimal comedogenic rating of 1, it is considered highly beneficial for aging, breakout-prone skin.
