Ingredients Details
Glutathione
Common Name(s): Gsh,gamma-l-glutamyl-l-cysteinyl-glycine,reduced glutathione
CAS Number: 70-18-8
DESCRIPTION
What It Does: Provides the body's primary antioxidant defense while reducing melanin production for brightening.
Why It's Used: Master antioxidant for comprehensive oxidative stress protection alongside unique melanin-shifting brightening action (pheomelanin preference).
How It Works: Three-amino acid tripeptide (gamma-glu-cys-gly). thiol group (-sh) provides electron donation for antioxidant activity and detoxification conjugation. shifts melanin synthesis from eumelanin (dark brown) toward pheomelanin (light yellow-red) for brightening. regenerates vitamins c and e from their oxidized forms.
Typically Found In: Brightening serums,antioxidant serums,anti-aging products
TECHNICAL DETAILS
Primary Category: Active ingredient โ master cellular antioxidant
Secondary Functions: Melanin shifting brightening,vitamins c+e regeneration,master antioxidant
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ5%
SOURCING & ETHICS
Vegan Status: Yes โ fermentation-derived
Halal Status: Yes
Source Notes: Produced by yeast fermentation or chemical synthesis. stability challenge โ use encapsulated or stabilized forms.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Well-tolerated; some reports of tingling at high concentrations.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Vitamin c,vitamin e,ferulic acid,spf,other antioxidants
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Glutathione's melanin-shifting mechanism (eumelaninโpheomelanin) is entirely different from tyrosinase inhibition. even in the presence of active tyrosinase, glutathione shifts the enzymatic product from dark eumelanin to lighter pheomelanin by chelating copper from the tyrosinase active site and competing for dopa substrate.

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

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.
