What Nykaa E retail limited Says
Product Description:
The Black Tea Boosting Serum enhances skin elasticity with fermented black tea (kombucha), peptide, and adenosine, providing healthy energy and vitality to rejuvenate skin that has lost its strength. This serum is formulated with EWG graded green and safe ingredients, certified as zero-irritation, and contains Coptis Japonica to soothe the skin. Macadamia seed oil improves wrinkles and dry skin, while seaberry awakens the skin's inner vitality and niacinamide brightens the complexion. It is recommended to use this serum in conjunction with Pyunkang Yul Enriched Cream and Deep Infusion Toner for a more moisturizing effect. The key ingredients include kombucha, fermented for 7 to 8 weeks, rich in polyphenol and catechin, to help keep skin firm and plump. The elastic, highly enriched formula replenishes the skin with nutrients, absorbing refreshingly without stickiness.

Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ10%
SOURCING & ETHICS

SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1โ2.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
1-2-hexanediol has an established safety and efficacy profile within the cosmetic regulatory framework at standard use concentrations.

Acetyl Hexapeptide-8
Common Name(s): Argireline plus,snap-6,acetyl glutamyl hexapeptide-3 modified
CAS Number: 616204-22-9
DESCRIPTION
What It Does: Inhibits neuromuscular acetylcholine release for reduced facial muscle contraction and expression line formation.
Why It's Used: Enhanced argireline analog with improved stability for formulations requiring optimized neuro-inhibiting anti-wrinkle performance.
How It Works: Competes with snap-25 protein for binding to the snare complex, reducing vesicular acetylcholine release at neuromuscular junctions. reduced acetylcholine binding decreases muscle contraction amplitude, reducing expression line depth with repeated use.
Typically Found In: Anti-wrinkle creams,expression line treatments,forehead/eye area products
TECHNICAL DETAILS
Primary Category: Active ingredient โ neurotransmitter-inhibiting peptide
Secondary Functions: Enhanced snare inhibition,improved stability
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 3โ1000 ppm
SOURCING & ETHICS
Vegan Status: Yes โ synthetic
Halal Status: Yes
Source Notes: Synthetically produced. encapsulation may improve delivery to neuromuscular junction.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Exceptional safety profile. ewg score: 1.
Works Well With: Hyaluronic acid,ceramides,retinol,moisturizers
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Hexapeptide-8 differs from argireline (hexapeptide-3) in its c-terminal modification that increases resistance to enzymatic degradation by skin proteases. this improved stability extends the bioavailability of the active peptide at the neuromuscular junction, potentially improving clinical anti-wrinkle efficacy vs the original argireline.

Acrylates/c10-30 Alkyl Acrylate Crosspolymer
Common Name(s): Acrylates/c10-30 alkyl acrylate crosspolymer
DESCRIPTION
What It Does: Delivers targeted skin-conditioning or bioactive benefits through a specific mechanism of action suited to the formulation's intended purpose.
Why It's Used: Specialty actives address specific skin concerns through targeted molecular mechanisms, providing efficacy beyond what base formulation ingredients alone can achieve.
How It Works: The bioactive compound interacts with specific molecular targets in skin cells or the extracellular matrix โ enzymes, receptors, structural proteins, or signaling molecules โ triggering beneficial biological responses.
Typically Found In: Serums,treatments,moisturizers,specialty products
TECHNICAL DETAILS

SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Specialty active ingredient; check individual sourcing for vegan status.
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,peptides
Avoid Combining With: Incompatible with oxidizing agents; check ph stability
SCIENTIFIC NOTE
Specialty actives typically work through enzyme inhibition (e.g., tyrosinase inhibition for brightening, mmp inhibition for anti-aging), receptor activation (e.g., retinoid receptors, ppar-ฮณ for barrier genes), or transcription factor modulation (e.g., nrf2 for antioxidant gene upregulation). structure-activity relationships determine potency and selectivity.
