Why This Works for Your Specific Profile
Damage Index:
Healthy to moderately damaged hair experiences over-conditioning or protein overload causing limpness or rigidity
Water Quality:
Dry or dull hair experiences increased brittleness from protein concentration without moisture balance
Hair:
Closed cuticles resist product penetration causing surface buildup without internal benefits
Active Lifestyle:
High activity and frequent washing rapidly strip product benefits requiring excessive reapplication

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.

Hydrolyzed Keratin
Common Name(s): Keratin peptides,soluble keratin,hydrolyzed wool protein
CAS Number: 69430-36-0
DESCRIPTION
What It Does: Repairs hair structure by penetrating and rebonding with damaged hair keratin proteins.
Why It's Used: The authentic hair repair ingredient โ same protein composition as hair itself, providing structural repair from within the cortex rather than surface coating alone.
How It Works: Hydrolyzed keratin peptides (500-2000 da) penetrate cuticle and cortex. cysteine thiol groups form disulfide bonds with oxidized keratin (rebonding). cross-links damaged cortex protein for improved tensile strength and reduced breakage. surface film formation fills cuticle gaps.
Typically Found In: Damage repair conditioners,hair masks,professional treatments
TECHNICAL DETAILS
Primary Category: Active ingredient โ keratin peptide
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 from wool (ovis aries) keratin; plant alternatives limited
Halal Status: Conditional โ wool source; verify halal certification
Source Notes: From hydrolyzed wool or feather keratin. plant-based (wheat keratin analog) available but different amino acid profile. marine keratin from squid pen also available.
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
Hair keratin is unique in its high cysteine content (~14%) forming extensive disulfide bond crosslinks. these disulfide bonds are disrupted by bleaching, heat, and chemical processing. hydrolyzed keratin's cysteine groups physically rebond into these disrupted sites โ a structural repair mechanism specific to keratin chemistry not achievable with any other protein hydrolysate.

Phenoxyethanol
Common Name(s): 2-phenoxyethanol,rose ether,ethylene glycol monophenyl ether

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

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.
