Ingredients Details
Copper Gluconate
Common Name(s): Cupric gluconate,copper(ii) d-gluconate
CAS Number: 0527-09-03
DESCRIPTION
What It Does: Provides bioavailable copper for skin enzyme cofactor functions including antioxidant, collagen crosslinking, and wound healing.
Why It's Used: Bioavailable organic copper for enzyme cofactor delivery to support antioxidant defense (sod), collagen maturation (lysyl oxidase), and wound healing.
How It Works: Cuยฒโบ is the cofactor for sod1 (antioxidant), tyrosinase (melanin), lysyl oxidase (collagen crosslinking), and cytochrome c oxidase (cellular energy). organic gluconate complexation improves bioavailability vs inorganic copper salts.
Typically Found In: Anti-aging serums,wound healing products,antioxidant formulations
TECHNICAL DETAILS
Primary Category: Active ingredient โ copper salt skin active
Secondary Functions: Sod cofactor,collagen crosslinking support,wound healing
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.01%โ0.5%
SOURCING & ETHICS
Vegan Status: Yes โ mineral/inorganic
Halal Status: Yes
Source Notes: Mineral/inorganic compound. cosmetic or pharmaceutical grade.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating at recommended concentrations.
Safe for Sensitive Skin: Yes at recommended concentrations
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile at cosmetic concentrations. ewg score: 1โ2.
Works Well With: Niacinamide,salicylic acid,other actives
Avoid Combining With: No significant incompatibilities at standard concentrations
SCIENTIFIC NOTE
Copper deficiency in skin manifests as impaired collagen crosslinking (reduced mechanical strength), reduced sod1 activity (increased oxidative stress), and hypopigmentation. topical copper supplementation addresses all three manifestations simultaneously through enzyme cofactor restoration.

Glycerin
Common Name(s): Glycerol,glycerine,1,2,3-propanetriol
CAS Number: 56-81-5
DESCRIPTION
What It Does: Glycerin pulls water from the environment and deeper skin layers into the outer skin layer (epidermis), boosting moisture levels and keeping skin soft, smooth, and plump.
Why It's Used: It is used in virtually every moisturizer, serum, and cleanser because it is highly effective at hydrating skin, is well-tolerated by all skin types, and enhances the texture and spreadability of formulations.
How It Works: As a humectant, glycerin forms hydrogen bonds with water molecules, trapping them in the skin. it also reinforces the skin barrier by integrating into lipid structures between skin cells.
Typically Found In: Moisturizers,serums,cleansers,toners,sheet masks,sunscreens,body lotions,shampoos,conditioners
TECHNICAL DETAILS
Primary Category: Humectant
Secondary Functions: Skin barrier support,emollient,solvent
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ30% (typical: 3โ10%)
SOURCING & ETHICS
Vegan Status: Yes โ plant-derived (coconut, soy, palm) or synthetic
Halal Status: Yes โ when plant-derived or synthetic; verify source with supplier
Source Notes: Derived from plant oils via hydrolysis or saponification; synthetic versions also available. palm-derived glycerin carries sustainability concerns.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low; non-irritating at all standard concentrations
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Extremely rare allergic reactions; generally safe for all skin types including sensitive and baby skin
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Widely recognized as safe. ewg hazard score: 1. no significant concerns for irritation, sensitization, or toxicity at typical concentrations (up to 50%).
Works Well With: Hyaluronic acid,ceramides,niacinamide,panthenol,urea,peptides,retinol,ahas/bhas
Avoid Combining With: No known incompatibilities at standard concentrations
SCIENTIFIC NOTE
Glycerin is an endogenous skin component found naturally in the stratum corneum. aquaporin-3 channels in keratinocytes facilitate glycerin transport, making it integral to natural skin hydration pathways.

Magnesium Aspartate
Common Name(s): Mineral salt,ionic strength modifier,skin mineralising agent
CAS Number: N/a
DESCRIPTION
What It Does: Provides mineral ion delivery to skin, modulates formulation ionic strength for viscosity and stability optimisation, and supports skin enzyme activity through essential mineral cofactor supplementation.
Why It's Used: Mineral salts are essential formulation ph and ionic strength adjusters โ magnesium sulfate specifically provides the mgยฒโบ ions that activate transglutaminase crosslinking during sc cornification, supporting barrier formation.
How It Works: Ionic dissociation in aqueous formulation provides free ions that modulate polymer viscosity (ionic strength reduces charge-based thickener swelling), provide mineral nutrition to skin enzymes (caยฒโบ for transglutaminase, mgยฒโบ for mgatp phosphotransferases), and adjust osmolality for skin-surface tonicity matching.
Typically Found In: All formulations,mineral skin care
TECHNICAL DETAILS
Primary Category: Active ingredient โ mineral / metal active
Secondary Functions: Antimicrobial,sebum regulation,antioxidant enzyme cofactor
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.01%โ5%
SOURCING & ETHICS
Vegan Status: Yes โ mineral
Halal Status: Yes
Source Notes: Mineral/inorganic compound. cosmetic or pharmaceutical grade.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating at recommended concentrations.
Safe for Sensitive Skin: Yes at recommended concentrations
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile at cosmetic concentrations. ewg score: 1โ2.
Works Well With: Niacinamide,salicylic acid,other actives
Avoid Combining With: No significant incompatibilities at standard concentrations
SCIENTIFIC NOTE
Mgยฒโบ and caยฒโบ are essential cofactors for the sc cornification process โ caยฒโบ specifically drives the caยฒโบ gradient across the epidermis (high in outer sc, low in basal layer) that regulates keratinocyte differentiation through caยฒโบ-calmodulin signalling.

Niacinamide
Common Name(s): Vitamin b3,nicotinamide,pyridine-3-carboxamide
CAS Number: 98-92-0
DESCRIPTION
What It Does: Niacinamide strengthens the skin barrier, reduces visible pore size, regulates sebum production, fades dark spots, and improves skin texture and tone.
Why It's Used: It is used because it addresses multiple skin concerns at once without irritation, making it suitable for all skin types. it is stable in formulations and pairs well with most other actives.
How It Works: Niacinamide inhibits the transfer of melanosomes (pigment packets) to skin cells, reducing hyperpigmentation. it also stimulates ceramide synthesis to strengthen the skin barrier and reduces inflammation by modulating cytokine activity.
Typically Found In: Serums,moisturizers,toners,cleansers,eye creams,sunscreens,primers

SCIENTIFIC NOTE
Niacinamide is a precursor to nad+ and nadp+, coenzymes vital to cellular energy metabolism. its benefits for dna repair and mitochondrial function make it a key ingredient in anti-aging strategies.
