Aloe Barbadensis Leaf Extract
Common Name(s): Aloe barbadensis leaf 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 surface through the plant's secondary metabolite complex.
Why It's Used: Chosen for its natural origin narrative, traditional use heritage, and multi-functional phytochemical profile that supports several concurrent skin care claims from one ingredient.
How It Works: Polyphenols, terpenoids, and alkaloids in the extract scavenge ros via hydrogen atom transfer, 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 โ antioxidant
Secondary Functions: Free radical scavenging,anti-aging
Application Areas:
Facial Skincare
Body Care

Arnica Montana Flower Extract
Common Name(s): Arnica montana flower 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 โ uv, microbial, and oxidative stressors โ that translate to skin benefits.
How It Works: Polyphenols (flavonoids, phenolic acids) inhibit nf-ฮบb-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: 0.1โ10%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Plant-derived extract; no animal components.
SKIN COMPATIBILITY
Irritancy Rating: 1
Comedogenicity Rating: 0
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 1โ50 ยตm), while antioxidant activity involves single electron transfer (set) and hydrogen atom transfer (hat) mechanisms with structure-dependent rate constants.
