Ingredients Details
Aloe Barbadensis Aloe Vera Leaf Juice
Common Name(s): Aloe barbadensis aloe vera leaf juice extract
DESCRIPTION
What It Does: Provides antioxidant protection, soothing anti-inflammatory effects, and skin-conditioning benefits through plant-derived polyphenols and phytochemicals.
Why It's Used: Plant extracts concentrate bioactive phytochemicals evolved for environmental protection — uv, microbial, and oxidative stressors — that translate to skin benefits.
How It Works: Polyphenols (flavonoids, phenolic acids) inhibit nf-κb-mediated inflammatory signaling, scavenge reactive oxygen species through electron donation, and chelate pro-oxidant metal ions to reduce oxidative skin damage.
Typically Found In: Serums,toners,moisturizers,masks,essences
TECHNICAL DETAILS
Primary Category: Botanical extracts
Secondary Functions: Antioxidant,anti-inflammatory
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1–10%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Plant-derived extract; no animal components.
SKIN COMPATIBILITY
Irritancy Rating: 1899-12-31 00:00:00 -0800
Sensitivity Concerns: Low sensitization potential at recommended use concentrations.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Well-characterized cosmetic ingredient with established safety profile. generally non-irritating at typical use concentrations. suitable for leave-on and rinse-off cosmetics.
Works Well With: Niacinamide,hyaluronic acid,vitamin c,ceramides
Avoid Combining With: Strong oxidizing agents
SCIENTIFIC NOTE
Plant secondary metabolites (flavonoids, terpenes, phenolic acids) are biosynthesized as defense compounds against uv, herbivores, and pathogens. their anti-inflammatory activity typically derives from competitive inhibition of cox-2 and 5-lox enzymes (ic50 1–50 µm), while antioxidant activity involves single electron transfer (set) and hydrogen atom transfer (hat) mechanisms with structure-dependent rate constants.

Euterpe Oleracea Fruit Extract
Common Name(s): Euterpe oleracea fruit extract,botanical extract,phytochemical active
CAS Number: N/a
DESCRIPTION
What It Does: Provides antioxidant protection from reactive oxygen species, reduces inflammatory cytokine production in skin, and conditions skin through the plant's phytochemical complex.
Why It's Used: Natural origin narrative, traditional use heritage, and multi-functional phytochemical profile supporting concurrent skin care claims from one ingredient.
How It Works: Polyphenols, terpenoids, and alkaloids scavenge ros via h• donation, inhibit nf-kb or cox-2 inflammatory pathways, and interact with skin surface proteins for conditioning.
Typically Found In: Botanical skin care,natural products
TECHNICAL DETAILS
Primary Category: Active ingredient – antioxidant
Secondary Functions: Free radical scavenging,anti-aging
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care

Gluconolactone
Common Name(s): D-gluconolactone,delta-gluconolactone
CAS Number: 90-80-2
DESCRIPTION
What It Does: Provides the gentlest chemical exfoliation with simultaneous antioxidant, moisture retention, and barrier support.
Why It's Used: Preferred exfoliant for rosacea, eczema, sensitive skin, and post-procedure recovery where standard ahas cause unacceptable irritation.
How It Works: Hydrolyzes slowly on skin surface to gluconic acid providing gentle exfoliation. multiple hydroxyl groups enable water binding (humectant) and metal chelation (antioxidant).
Typically Found In: Sensitive skin exfoliants,rosacea treatments,eczema care,post-procedure recovery
TECHNICAL DETAILS
Primary Category: Active ingredient – polyhydroxy acid (pha)
Secondary Functions: Gentle exfoliation,antioxidant,humectant
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 5%–15%
SOURCING & ETHICS
Vegan Status: Yes – fermentation or synthetic
Halal Status: Yes
Source Notes: Fermentation-derived from glucose or synthetic. among the safest chemical exfoliants available.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: No photosensitization; no stinging; suitable for very sensitive skin.
Safe for Sensitive Skin: Yes – ideal for sensitive, reactive, rosacea, and eczema-prone skin; no photosensitization
SAFETY & COMPATIBILITY
Safety Profile: Exceptional safety profile. no photosensitization. ewg score: 1.
Works Well With: Ceramides,niacinamide,hyaluronic acid,soothing actives
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Phas have molecular weights 2–3× larger than ahas, limiting penetration to superficial layers. combined humectant and antioxidant properties make them uniquely well-tolerated while providing meaningful exfoliation.

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.
