What Earth Rhythm Says
Product Description:
Earth Rhythm Moisture Punch Multi - Molecular Hyaluronic Acid Serum contains ultra-low molecular weight sodium hyaluronate obtained by the bio-enzyme chain breakage technology based on the ordinary sodium hyaluronate. This serum penetrates deep into the skin layers due to its molecular weight being lower than 10 kDa and an average size smaller than 25 nm, while the intercellular space is around 40-50 nm. It also contains a combination of five essential ceramide complex which helps the skin retain moisture and function properly, keeping it hydrated, soft, and plump. The serum plumps, hydrates, and locks moisture. Formulated without parabens, sulphates, phthalates, formaldehyde, mineral oil, triclosan, and harmful chemicals. It is organic certified, biodegradable, minimally packed with recycled and recyclable materials over 99% plastic-free, cruelty-free, and made with plant-based wild harvested herbs sourced responsibly.

Cholesterol
Common Name(s): 5-cholesten-3-ol,cholesterin
CAS Number: 57-88-5
DESCRIPTION
What It Does: Provides essential barrier sterol function as one of three critical stratum corneum lipid components.
Why It's Used: Essential component of complete barrier repair formulations โ the stratum corneum barrier requires ceramides:cholesterol:fatty acids in approximately 1:1:1 molar ratio for complete barrier restoration.
How It Works: Integrates between ceramide headgroups in lamellar body structures, providing fluidity and flexibility to the otherwise rigid ceramide-dominated lipid matrix. controls lamellar body phase behavior for functional barrier.
Typically Found In: Barrier repair moisturizers,eczema treatments,dry skin formulations
TECHNICAL DETAILS
Primary Category: Active ingredient โ barrier sterol
Secondary Functions: Lamellar body structure,barrier sterol
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.01%โ1%
SOURCING & ETHICS
Vegan Status: Conditional โ animal-derived (lanolin) or plant-derived phytosterol analogs; verify
Halal Status: Conditional โ verify source
Source Notes: Traditionally from lanolin (wool grease). plant-derived cholesterol alternatives include phytosterols, though these show slightly different barrier integration. verify for vegan/halal.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Endogenous molecule; excellent tolerability.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Exceptional safety profile. natural skin component. ewg score: 1.
Works Well With: Other ceramides,cholesterol,free fatty acids,hyaluronic acid,niacinamide
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Elias demonstrated that barrier repair requires all three lipid classes (ceramides, cholesterol, fatty acids) in approximately equimolar ratios. formulations providing only ceramides without cholesterol and fatty acids show significantly inferior barrier restoration vs complete triple-lipid combinations.

Phenoxyethanol
Common Name(s): 2-phenoxyethanol,rose ether,ethylene glycol monophenyl ether
CAS Number: 122-99-6
DESCRIPTION
What It Does: Prevents microbial contamination and spoilage in cosmetic formulations.
Why It's Used: The benchmark cosmetic preservative โ eu-permitted up to 1%, effective against virtually all cosmetically relevant microorganisms, and excellent tolerability.
How It Works: Phenol ring provides broad antimicrobial activity via disruption of bacterial and fungal cell membranes and inhibition of enzymatic activity. effective against gram-positive and gram-negative bacteria, yeasts (candida), and molds (aspergillus). activity ph range: 3-9.
Typically Found In: All cosmetic formulations as primary preservative
TECHNICAL DETAILS
Primary Category: Functional ingredient โ broad-spectrum preservative
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ1% (eu max 1%)
SOURCING & ETHICS

SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Eu cosmetics regulation max 1%. sccs assessed as safe at โค1%. avoid use around eyes in baby products per some country regulations. ewg score: 4.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Phenoxyethanol's widespread adoption as the primary cosmetic preservative followed the phaseout of parabens from many formulations in the 2000s-2010s. despite having a comparable or better safety profile to parabens, it is often cited in 'free-from' formulations โ a consumer perception issue rather than a scientific safety concern.

Water
Common Name(s): Water,purified water,deionised water,inci water
CAS Number: 7732-18-5
DESCRIPTION
What It Does: Provides the universal solvent and vehicle for water-soluble actives and the continuous phase of all o/w emulsions.
Why It's Used: The most essential cosmetic ingredient โ aqua (water) is listed first on virtually all water-containing cosmetic inci labels as the highest-concentration ingredient, serving as the foundation of the global cosmetics industry.
How It Works: Acts as solvent for all water-soluble ingredients (glycols, amino acids, water-soluble actives). forms the continuous external phase of o/w emulsions (lotions, creams, serums). provides aqueous environment for enzymatic and chemical reactions between actives. ph adjustment medium.
Typically Found In: Virtually all cosmetic products โ the most universal cosmetic ingredient globally
TECHNICAL DETAILS
Primary Category: Functional ingredient โ water

SCIENTIFIC NOTE
Water's position as the first inci ingredient on most cosmetic labels reflects the regulatory requirement to list ingredients in descending concentration order โ meaning water is the most abundant ingredient in the majority of cosmetic products. the fundamental role of water as the universal cosmetic solvent and vehicle makes it simultaneously the most important cosmetic ingredient and the one that requires the most sophisticated formulation chemistry to control โ every emulsifier, thickener, preservative, and ph adjuster exists primarily to manage water's interaction with other ingredients in formulation.
