Hyaluronic Acid Essential Hydrating Serum
Serum

A brilliantly formulated, minimalist hydration engine that acts as a pure drink of water for thirsty cells. Instead of relying solely on heavy polymers, Cosmoderm loads this serum with a massive complex of Natural Moisturizing Factors (NMFs). It features Sodium PCA, Trehalose, and a comprehensive suite of skin-identical Amino Acids (Serine, Alanine, Glycine, Proline). This allows the fluid to mimic the skins biological hydration system directly. The texture is an absolute weightless water gel that absorbs instantly, immediately relieving tight, pulling sensations.

Cleanser

A highly elegant, biomimetic first-step makeup remover. By utilizing exceptionally mild emulsifiers (PEG-6 Caprylic/Capric Glycerides and Olive Oil PEG-7 Esters) instead of harsh detergents, it grabs heavy cosmetic polymers and lifts them away without disturbing native cellular lipids. The massive hydration payload of Sodium PCA, Betaine, and Hyaluronic Acid ensures the skin surface feels incredibly soft and conditioned after wiping, making it an elite choice for extremely reactive barriers that cannot tolerate traditional oil balms.
