Dihé (Blue-Green Algae) Serum

Dihé (ديحي, pronounced dee-heh) is the Amazigh word for blue-green algae cakes, traditionally harvested along the shores of Lake Chad.

This lightweight serum blends vegan DMAE, OptiMSM, blue-green algae, and meadowfoam seed oil to create a transformative daily ritual. Silken and rapidly absorbing, it replenishes skin with a potent concentration of antioxidants, plant oils, and restorative compounds that soften, firm, and hydrate. Free of added fragrance, it carries only the faint, earthy scent of its botanicals—inviting simplicity and mindful care with every application.

Across the Sahel and beyond, blue-green algae has long been prized for its ability to restore strength and vitality—revered by Kanembu women as both sustenance and medicine. Harvested and dried into cakes, dihé sustained generations through scarcity and nourished communities with rare minerals and proteins. Today, modern science affirms these ancient practices: blue-green algae delivers amino acids and vitamins that support the skin’s resilience, while MSM and DMAE work synergistically to improve tone and elasticity.

Vitamins E and meadowfoam oil seal in moisture and protect against oxidative stress, while aloe vera soothes and replenishes. Together, these ingredients help defend against the visible effects of aging—restoring luminosity, suppleness, and balance.
