KAYA 10% NIACINAMIDE + 1% AZELOGLYCINA FACE SERUM, DARK SPOT CORRECTOR

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 – 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%–10% (typical: 5%; higher concentrations may cause flushing in some individuals)

SOURCING & ETHICS

Vegan Status: Yes – synthetically produced

Halal Status: Yes – 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 – very low; concentrations above 10% may cause temporary flushing in sensitive individuals

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: At concentrations >10%, some users experience niacin flush (transient redness/tingling). generally very well-tolerated.

Safe for Sensitive Skin: Yes – 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 – 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.

DESCRIPTION

What It Does: Simultaneously regulates sebum and hydrates via nmf-pca component for oily-dehydrated combination skin.

Why It's Used: Unique dual-function ingredient addressing the paradox of oily-yet-dehydrated skin with sebum control (zinc) + nmf hydration (pca) from one molecule.

How It Works: Zinc ion component inhibits 5-alpha-reductase and p. acnes. pca component provides nmf-type humectant hydration. combined in the zinc-pca salt for simultaneous delivery of both activities.

Typically Found In: Combination skin products,anti-acne moisturizers,oily skin hydration

TECHNICAL DETAILS

Primary Category: Active ingredient – zinc nmf complex

Secondary Functions: Sebum control,nmf hydration,anti-acne

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.1%–1%

SOURCING & ETHICS

Vegan Status: Yes – mineral/inorganic

Halal Status: Yes

Source Notes: Mineral/inorganic compound. cosmetic or pharmaceutical grade.

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: Non-irritating at recommended concentrations.

Safe for Sensitive Skin: Yes at recommended concentrations

SAFETY & COMPATIBILITY

Safety Profile: Excellent safety profile at cosmetic concentrations. ewg score: 1–2.

Works Well With: Niacinamide,salicylic acid,other actives

Avoid Combining With: No significant incompatibilities at standard concentrations

SCIENTIFIC NOTE

The combination of sebum regulation and nmf hydration in zinc pca addresses the clinically common oily-dehydrated skin phenotype, where excess sebum is accompanied by inadequate water binding in the stratum corneum – a condition poorly served by either humectants (worsen oiliness) or astringents alone.
