What The Ordinary Says
Product Description:
A serum with an intensely hydrating effect that combines exopolysaccharides from skin-friendly marine bacteria, Hawaiian red algae, glycoproteins from Antarctic marine sources, micro-filtered blue-green algae, and several amino acids. This water-based formula targets hydration below the skin surface, resulting in a softer, plumper complexion.

Alanine
Common Name(s): L-alanine,2-aminopropanoic acid
CAS Number: 56-41-7
DESCRIPTION
What It Does: Provides nmf-type humectant moisture retention and skin conditioning.
Why It's Used: Simple, well-tolerated nmf amino acid humectant for skin conditioning formulations.
How It Works: Small methyl side chain contributes to protein hydrophobic core but as free amino acid provides direct humectant activity via amino and carboxyl groups. converted to pyruvate for cellular atp production via gluconeogenesis.
Typically Found In: Nmf moisturizers,skin conditioning products
TECHNICAL DETAILS
Primary Category: Active ingredient โ amino acid
Secondary Functions: Nmf component,cellular energy
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.5%โ5%
SOURCING & ETHICS
Vegan Status: Yes โ plant-derived or synthetic
Halal Status: Yes
Source Notes: Fermentation-derived or synthetic. natural skin component.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating; endogenous skin molecule.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. natural skin nmf component. ewg score: 1.
Works Well With: Hyaluronic acid,ceramides,peptides,other amino acids
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Free alanine is among the most abundant amino acids in the stratum corneum nmf, where it contributes to the aqueous phase hydration that keeps the stratum corneum flexible and functional.

Algae Extract
Common Name(s): Algae extract,botanical extract,phytochemical active
CAS Number: N/a
DESCRIPTION
What It Does: Provides antioxidant protection from reactive oxygen species, reduces inflammatory cytokine production in skin, and conditions skin surface through the plant's secondary metabolite complex.
Why It's Used: Chosen for its natural origin narrative, traditional use heritage, and multi-functional phytochemical profile that supports several concurrent skin care claims from one ingredient.
How It Works: Polyphenols, terpenoids, and alkaloids in the extract scavenge ros via hydrogen atom transfer, inhibit nf-kb or cox-2 inflammatory pathways, and interact with skin surface proteins for conditioning.
Typically Found In: Botanical skin care,natural products

Arginine
Common Name(s): L-arginine,2-amino-5-guanidinopentanoic acid
CAS Number: 74-79-3
DESCRIPTION
What It Does: Conditions skin, attracts moisture, supports wound healing, and improves microcirculation via no synthesis.
Why It's Used: Multi-functional amino acid for skin hydration, conditioning, and wound healing in peptide and nmf formulations.
How It Works: Guanidinium group binds water (humectant). substrate for nitric oxide synthase (enos) producing nitric oxide that vasodilates capillaries improving skin nutrition. stimulates fibroblast proliferation for wound healing.
Typically Found In: Anti-aging serums,wound healing products,nmf moisturizers,scalp treatments
TECHNICAL DETAILS
Primary Category: Active ingredient โ amino acid
Secondary Functions: Wound healing,microcirculation,nmf component
