Ingredients Details
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.

Lecithin
Common Name(s): Soy lecithin,sunflower lecithin,phosphatidylcholine complex
CAS Number: 8002-43-5
DESCRIPTION
What It Does: Provides natural phospholipid emulsification with barrier-compatible delivery and liposome-forming properties.
Why It's Used: The most biologically authentic emulsifier โ identical to cell membrane composition providing barrier-compatible delivery and liposome formation unavailable from synthetic emulsifiers.
How It Works: Phosphatidylcholine (pc), phosphatidylethanolamine (pe), phosphatidylinositol (pi) mixture provides hlb 7-12 for o/w emulsification. forms liposomal bilayers for active encapsulation. pc/pe/pi composition mirrors cell membrane for barrier-compatible delivery.
Typically Found In: Natural cosmetics,liposomal products,barrier repair,penetration-enhanced formulas
TECHNICAL DETAILS
Primary Category: Functional ingredient โ natural phospholipid emulsifier
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.5%โ10%
SOURCING & ETHICS
Vegan Status: Conditional โ soy lecithin (vegan); egg lecithin (not vegan)
Halal Status: Conditional โ soy (halal); egg (verify)
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
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: Good safety profile at recommended concentrations. ewg score: 1โ2.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Lecithin's phospholipid composition mirrors the composition of the stratum corneum's own lamellar bodies that deliver barrier lipids to the skin surface. this structural mimicry allows lecithin-based delivery systems to integrate seamlessly with the barrier lipid structure, exploiting the same transport pathway the skin uses for its own lipid secretion.

Panthenol
Common Name(s): Provitamin b5,d-panthenol,dl-panthenol,d-pantothenyl alcohol,(r)-2,4-dihydroxy-n-(3-hydroxypropyl)-3,3-dimethylbutanamide
DESCRIPTION
What It Does: Panthenol deeply moisturizes skin and hair, soothes irritation, accelerates wound healing, strengthens the skin barrier, and improves hair elasticity and shine.
Why It's Used: It is used because it is exceptionally versatile, working in both skin and hair formulations. it is gentle enough for sensitive and post-procedure skin, and converts to the active vitamin b5 within the skin.
How It Works: Panthenol penetrates skin and hair, where it is oxidized to pantothenic acid (vitamin b5), a coenzyme a precursor essential to metabolism. in skin, it acts as a humectant and stimulates fibroblast proliferation. in hair, it coats the shaft, improving manageability.
Typically Found In: Moisturizers,serums,toners,after-sun products,wound healing products,shampoos,conditioners,hair masks,beard care
TECHNICAL DETAILS
Primary Category: Active ingredient โ provitamin b5
Secondary Functions: Anti-inflammatory,wound healing,hair conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.5%โ5% (typical: 1โ3%)
SOURCING & ETHICS
Vegan Status: Yes โ synthetically produced
Halal Status: Yes
Source Notes: Commercially synthesized. both d- and dl-forms used in cosmetics; d-panthenol is the biologically active isomer but dl-panthenol is less expensive and widely used.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low; one of the most soothing ingredients in cosmetics
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Extremely rare contact allergy; considered one of the safest cosmetic ingredients. suitable for all skin types.
Safe for Sensitive Skin: Yes โ ideal for sensitive, reactive, and post-procedure skin
SAFETY & COMPATIBILITY
Safety Profile: Exceptionally safe. ewg hazard score: 1. no significant concerns for irritation, sensitization, or systemic toxicity. safe during pregnancy.
Works Well With: Hyaluronic acid,ceramides,allantoin,niacinamide,centella asiatica,retinol (reduces irritation),glycerin
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Panthenol has demonstrated wound-healing properties in clinical studies, stimulating fibroblast proliferation and migration. its dual humectant and anti-inflammatory action makes it particularly effective in barrier-repair formulations.

Squalane
Common Name(s): Perhydrosqualene,2,6,10,15,19,23-hexamethyltetracosane
CAS Number: 0111-01-03
DESCRIPTION
What It Does: Provides endogenous-skin-identical emolliency with exceptional stability and skin compatibility.
Why It's Used: The most skin-compatible emollient โ chemically identical to human sebum squalene component with outstanding tolerability across all skin types.
How It Works: Fully saturated hydrocarbon with zero oxidation sites provides exceptional stability unlike squalene's 6 double bonds. integrates into stratum corneum lipid bilayers with near-perfect biocompatibility. provides antioxidant protection to formulation via radical quenching.
Typically Found In: Facial oils,serums,non-comedogenic moisturizers,luxury body care
TECHNICAL DETAILS
Primary Category: Functional ingredient โ emollient
Secondary Functions: Maximum biocompatibility,antioxidant stabilizer,non-comedogenic
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ100%
SOURCING & ETHICS
Vegan Status: Conditional โ plant-derived (sugarcane, olive) preferred; shark liver-derived being phased out
Halal Status: Yes โ plant-derived
Source Notes: Sustainable plant-derived squalane from sugarcane fermentation (amyris) or olive oil fractionation is preferred over shark liver-derived. chemically identical regardless of source.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Humectants,ceramides,actives as carrier
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Squalene constitutes approximately 12-15% of human sebum โ the highest proportion of any skin lipid. topical squalane (stable, hydrogenated form) replenishes this abundant endogenous skin lipid. the complete absence of oxidizable double bonds (unlike squalene's 6 double bonds) eliminates the pro-oxidant concerns of natural squalene oxidation.
