Why This Works for Your Specific Profile

Damage Index:

Damaged hair structure cannot withstand product intensity causing increased breakage and further compromise

Water Quality:

Medium to coarse textures require more intensive formulation than lightweight product provides

Hair:

Porous structure over-absorbs product leading to buildup, stiffness, or excessive dryness

Active Lifestyle:

Activity levels outside optimal range affect product performance and maintenance requirements

Ingredients Details

Apigenin

Common Name(s): 4',5,7-trihydroxyflavone,versulin,apigenol

CAS Number: 520-36-5

DESCRIPTION

What It Does: Provides gaba-a receptor-mediated skin calming and anti-inflammatory activity from chamomile.

Why It's Used: The calming flavone โ€” apigenin's documented gaba-a agonism provides the pharmacological basis for chamomile's well-documented calming activity, providing the most evidence-based neurocosmetic flavonoid mechanism.

How It Works: Apigenin binds gaba-a receptor benzodiazepine site (ic50 ~4ฮผm) for calming activity. cox and 5-lox inhibition provides anti-inflammatory activity. anti-proliferative via cdk2 and cdk6 inhibition. uv-absorbing chromophore provides mild photoprotection. very low water solubility โ€” requires formulation.

Typically Found In: Sensitive skin calming products,chamomile formulas,anti-anxiety skincare

TECHNICAL DETAILS

Primary Category: Active ingredient โ€“ soothing / anti-inflammatory

Secondary Functions: Redness reduction,anti-inflammatory,calming

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.01%โ€“2%

SOURCING & ETHICS

Vegan Status: Yes โ€“ from matricaria recutita or anthemis nobilis flowers

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: Non-irritating; ideal for reactive and sensitive 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

Apigenin's gaba-a benzodiazepine site binding (same binding site as valium/diazepam) was first demonstrated by viola et al. (1995) confirming the pharmacological mechanism behind chamomile's traditional calming use. apigenin provides partial benzodiazepine site agonism rather than full agonism like pharmaceutical benzodiazepines โ€” providing calming without sedative or addictive properties, explaining chamomile's safety advantage over pharmaceutical anxiolytics.

Arginine

Common Name(s): L-arginine,2-amino-5-guanidinopentanoic acid

CAS Number: 74-79-3

DESCRIPTION

What It Does: Conditions skin, attracts moisture, supports wound healing, and improves microcirculation via no synthesis.

Why It's Used: Multi-functional amino acid for skin hydration, conditioning, and wound healing in peptide and nmf formulations.

How It Works: Guanidinium group binds water (humectant). substrate for nitric oxide synthase (enos) producing nitric oxide that vasodilates capillaries improving skin nutrition. stimulates fibroblast proliferation for wound healing.

Typically Found In: Anti-aging serums,wound healing products,nmf moisturizers,scalp treatments

TECHNICAL DETAILS

Primary Category: Active ingredient โ€“ amino acid

Secondary Functions: Wound healing,microcirculation,nmf component

Application Areas:

Facial Skincare

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.5%โ€“5%

SOURCING & ETHICS

Vegan Status: Yes โ€“ plant-derived or synthetic

SKIN COMPATIBILITY

Irritancy Rating: 1/5 โ€“ very low

Comedogenicity Rating: 0/5 โ€“ non-comedogenic

Sensitivity Concerns: Non-irritating; endogenous skin molecule.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Excellent safety profile. natural skin nmf component. ewg score: 1.

Works Well With: Hyaluronic acid,ceramides,peptides,other amino acids

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Arginine is a conditionally essential amino acid in wound healing where local demand exceeds synthesis capacity. topical arginine provides the nos substrate locally for no-mediated vasodilation and immune cell function in healing tissue.
