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 – 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 – 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%–2%
SOURCING & ETHICS
Vegan Status: Yes – synthetic or comfrey-derived

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.

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%–30% (typical: 3–10%)
SOURCING & ETHICS
Vegan Status: Yes – plant-derived (coconut, soy, palm) or synthetic
Halal Status: Yes – 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 – very low; non-irritating at all standard concentrations
Comedogenicity Rating: 0/5 – 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.

Safety Profile: Eu cosmetics regulation max 1%. sccs assessed as safe at ≤1%. 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 – a consumer perception issue rather than a scientific safety concern.
