Ingredients Details
Niacinamide
Common Name(s): Vitamin b3,nicotinamide,pyridine-3-carboxamide
CAS Number: 98-92-0
DESCRIPTION
What It Does: Niacinamide strengthens the skin barrier, reduces visible pore size, regulates sebum production, fades dark spots, and improves skin texture and tone.
Why It's Used: It is used because it addresses multiple skin concerns at once without irritation, making it suitable for all skin types. it is stable in formulations and pairs well with most other actives.
How It Works: Niacinamide inhibits the transfer of melanosomes (pigment packets) to skin cells, reducing hyperpigmentation. it also stimulates ceramide synthesis to strengthen the skin barrier and reduces inflammation by modulating cytokine activity.
Typically Found In: Serums,moisturizers,toners,cleansers,eye creams,sunscreens,primers
TECHNICAL DETAILS
Primary Category: Active ingredient โ vitamin
Secondary Functions: Barrier repair,brightening,anti-inflammatory
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 2%โ10% (typical: 5%; higher concentrations may cause flushing in some individuals)
SOURCING & ETHICS
Vegan Status: Yes โ synthetically produced
Halal Status: Yes โ synthetic origin
Source Notes: Commercially produced via synthesis from nicotinic acid or 3-cyanopyridine. no animal-derived sources used in cosmetic-grade niacinamide.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low; concentrations above 10% may cause temporary flushing in sensitive individuals
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: At concentrations >10%, some users experience niacin flush (transient redness/tingling). generally very well-tolerated.
Safe for Sensitive Skin: Yes โ one of the best-tolerated actives for sensitive skin
SAFETY & COMPATIBILITY
Safety Profile: Extensively studied and considered very safe. ewg hazard score: 1. no significant systemic toxicity concerns at topical concentrations.
Works Well With: Retinol,peptides,ahas/bhas,hyaluronic acid,ceramides,zinc,vitamin c,spf
Avoid Combining With: High concentrations of vitamin c (ascorbic acid) may theoretically convert to niacin โ use at different times if using pure l-ascorbic acid above 15%
SCIENTIFIC NOTE
Niacinamide is a precursor to nad+ and nadp+, coenzymes vital to cellular energy metabolism. its benefits for dna repair and mitochondrial function make it a key ingredient in anti-aging strategies.

Water(aqua/eau)
Common Name(s): Water(aqua/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: 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 1โ50 ยตm), while antioxidant activity involves single electron transfer (set) and hydrogen atom transfer (hat) mechanisms with structure-dependent rate constants.
