Ingredients Details
Aqua/water/eau
Common Name(s): Aqua/water/eau 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.

Pha
Common Name(s): Polyhydroxy acid (pha),gentle large-molecule exfoliant,sensitive skin aha
CAS Number: N/a
DESCRIPTION
What It Does: Provides gentle keratolytic exfoliation, skin brightening, and humectant moisture retention simultaneously โ with a skin-irritation profile significantly lower than glycolic or lactic acid from slower penetration kinetics.
Why It's Used: The gold standard for sensitive skin chemical exfoliation โ phas provide aha-class exfoliation efficacy in fitzpatrick ivโvi and rosacea skin types where glycolic acid is too aggressive.
How It Works: Multiple hydroxyl groups on the pha molecule slow sc penetration (fick's law: d โ mw^-0.7) providing gentler keratolytic action. the hydroxyl groups also bind water providing simultaneous humectancy and chelate caยฒโบ to disrupt desmosomal adhesion for exfoliation.
Typically Found In: Sensitive skin,exfoliating toners,post-procedure
TECHNICAL DETAILS
Primary Category: Active ingredient โ alpha hydroxy acid (aha)
Secondary Functions: Brightening,collagen stimulation
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ15%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Fermentation-derived or synthetic. ph must be โค4.0 for aha activity.
SKIN COMPATIBILITY
Irritancy Rating: 2/5 โ low to moderate
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Photosensitizing โ mandatory spf use. start at low frequency.
Safe for Sensitive Skin: Use with caution โ spf required
SAFETY & COMPATIBILITY
Safety Profile: Safe at otc concentrations. eu: โค10% leave-on at ph โฅ3.5. mandatory spf advisory.
Works Well With: Niacinamide,ceramides,hyaluronic acid,spf
Avoid Combining With: Retinol in same step; multiple exfoliants simultaneously
SCIENTIFIC NOTE
Phas have a water of hydration shell from multiple oh groups that further slows sc penetration versus equivalent-mw ahas โ the combined larger mw and greater hydration shell providing the gentlest keratolytic delivery kinetics of all acid exfoliants.
