Ingredients Details
Allantoin
Common Name(s): 5-ureidohydantoin,glyoxyldiureide,aluminum dihydroxy allantoinate
CAS Number: 97-59-6
DESCRIPTION
What It Does: Soothes irritation, accelerates wound healing, promotes skin cell renewal, and provides mild keratolytic exfoliation.
Why It's Used: Gold standard multi-function soothing active โ one of the most widely used cosmetic ingredients across all product types for its exceptional tolerability and clinically proven multi-action skin conditioning.
How It Works: Promotes keratinocyte proliferation and fibroblast migration for wound healing. mild keratolytic activity by disrupting corneocyte binding. anti-irritant via direct protein binding and anti-inflammatory cytokine reduction. humectant activity via hydroxyl groups.
Typically Found In: Post-procedure products,sensitive skin formulas,wound care,anti-acne treatments,baby products
TECHNICAL DETAILS
Primary Category: Active ingredient โ soothing / anti-inflammatory
Secondary Functions: Wound healing,keratolytic,anti-irritant
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ2%
SOURCING & ETHICS
Vegan Status: Yes โ synthetic or comfrey-derived
Halal Status: Yes
Source Notes: Plant-derived extract or synthetic.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Exceptionally well-tolerated; suitable for all skin types including baby and compromised skin.
Safe for Sensitive Skin: Yes โ particularly recommended for sensitive skin
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Ceramides,panthenol,allantoin,hyaluronic acid,centella asiatica
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Allantoin's keratinocyte proliferation stimulation occurs via receptor-mediated signaling (possibly machr activation) rather than non-specific irritation-driven proliferation, making it a true wound-healing stimulant rather than a pro-inflammatory proliferative signal.

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
TECHNICAL DETAILS
Primary Category: Active ingredient โ vitamin
Secondary Functions: Barrier repair,brightening,anti-inflammatory
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 2%โ10% (typical: 5%; higher concentrations may cause flushing in some individuals)
SOURCING & ETHICS
Vegan Status: Yes โ synthetically produced
Halal Status: Yes โ synthetic origin
Source Notes: Commercially produced via synthesis from nicotinic acid or 3-cyanopyridine. no animal-derived sources used in cosmetic-grade niacinamide.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low; concentrations above 10% may cause temporary flushing in sensitive individuals
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: At concentrations >10%, some users experience niacin flush (transient redness/tingling). generally very well-tolerated.
Safe for Sensitive Skin: Yes โ one of the best-tolerated actives for sensitive skin
SAFETY & COMPATIBILITY
Safety Profile: Extensively studied and considered very safe. ewg hazard score: 1. no significant systemic toxicity concerns at topical concentrations.
Works Well With: Retinol,peptides,ahas/bhas,hyaluronic acid,ceramides,zinc,vitamin c,spf
Avoid Combining With: High concentrations of vitamin c (ascorbic acid) may theoretically convert to niacin โ use at different times if using pure l-ascorbic acid above 15%
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.

Propanediol
Common Name(s): 1,3-propanediol,zemea,bio-propanediol
CAS Number: 504-63-2
DESCRIPTION
What It Does: Provides humectant and solvent functionality from sustainable corn-based fermentation.
Why It's Used: Bio-based propylene glycol alternative from renewable corn โ propanediol provides equivalent functionality to propylene glycol with sustainable renewable feedstock and superior skin feel.
How It Works: Two oh groups provide humectant water binding. excellent solvent for fragrances, actives, and preservatives. mild antimicrobial from diol structure for preservative system boosting. renew corn fermentation origin (dupont zemea process). better skin feel than propylene glycol โ less sticky.
Typically Found In: Virtually all cosmetic categories as pg alternative
TECHNICAL DETAILS
Primary Category: Functional ingredient โ humectant
Secondary Functions: Tewl reduction,skin plumping
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ20%
SOURCING & ETHICS
Vegan Status: Yes โ from corn sugar fermentation
Halal Status: Yes
Source Notes: Synthetic or naturally derived. excellent aqueous solubility.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating; suitable for all skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Ceramides,emollients,occlusives,glycerin,hyaluronic acid
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Propanediol's dupont tate & lyle bio products 'zemea' process ferments corn sugar to 1,3-propanediol using engineered e. coli โ one of the first commercially viable bio-fermentation routes to a cosmetic diol previously made only from petroleum. the renewable route produces chemically identical 1,3-propanediol while reducing carbon footprint by approximately 40% vs petrochemical synthesis.

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

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.
