Key Information
What Nykaa E retail limited Says
Product Description:
Dark Skin on the back, neck, knee & Elbows is very common. It’s a form of hyperpigmentation due to the accumulation of excess melanin. Sometimes these are associated with dryness. This serum lightens the colour of the affected area with Glycolic Acid and moisturizes the skin through enriched Glycolic Acid, Sodium Lactate. Neroli Essential Oil, Syn-Coll & Pro Vitamin B5 contribute to smooth, soft skin by regenerating skin Collagen production & providing nourishing effects. Glycolic Acid exfoliates dead skin cells, brightens, and refreshes lackluster skin while reducing lines and wrinkles. Neroli Essential Oil improves skin elasticity and promotes cell regeneration, also helping with scarring and stretch marks. SYN-COLL peptide helps produce collagen, slows aging, fights fine lines and wrinkles, improves firmness, elasticity, and texture. Usage: apply serum before bedtime on cleaned dry affected area, wash off next day, use daily for 3-4 weeks then twice weekly until desired results.

Ingredients Details
Geraniol
Common Name(s): (e)-3,7-dimethyl-2,6-octadien-1-ol,geranyl alcohol
CAS Number: 106-24-1
DESCRIPTION
What It Does: Provides fresh rose-geranium floral scent with antimicrobial activity.
Why It's Used: The rose fragrance terpene – geraniol defines the fresh, sweet rose-geranium note found in more than 60 essential oils and is essential for recreating natural floral fragrance profiles.
How It Works: Monoterpene alcohol inhibits bacterial membrane integrity for antimicrobial activity. activates trpv1 for anti-nociception. inhibits nf-kb for anti-inflammatory activity. antioxidant via allylic radical scavenging.
Typically Found In: Rose-scented products,floral fragrances,natural cosmetics
TECHNICAL DETAILS
Primary Category: Fragrance component – acyclic monoterpene alcohol
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.001%–1%
SOURCING & ETHICS
Vegan Status: Yes – from rose, geranium, palmarosa oils
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Eu cosmetics regulation: declared fragrance allergen. ifra guidelines apply.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Geraniol's isomers (geraniol, nerol, citronellol) provide subtly different scent characters despite identical molecular formulae (c10h18o): geraniol provides the sweet, fresh rose note while its z-isomer nerol has a more delicate, neroli-like character. these isomeric scent differences arise from different spatial presentation of the hydroxyl and double bond groups to the olfactory receptor – demonstrating the extraordinary structural sensitivity of olfactory perception.

Limonene
Common Name(s): D-limonene,(r)-limonene,dipentene
CAS Number: 5989-27-5
DESCRIPTION
What It Does: Provides the defining fresh citrus fragrance note alongside solvent and antimicrobial properties.
Why It's Used: The citrus industry's primary fragrance compound and the most abundant terpene in essential oils – limonene provides the clean, universally appealing fresh citrus scent character.
How It Works: D-limonene activates trpv1 mildly at high concentrations. antimicrobial via membrane disruption. solvent for oils and lipophilic compounds. cleaning via emulsification of lipid soils.
Typically Found In: Citrus-scented products,cleaning products,fragrance compounds
TECHNICAL DETAILS
Primary Category: Fragrance component – cyclic monoterpene
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.001%–3%
SOURCING & ETHICS
Vegan Status: Yes – from citrus peel essential oils
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Eu cosmetics regulation: declared fragrance allergen. oxidises to sensitising compounds (limonene hydroperoxides) on air exposure – use with antioxidant stabilisers. ifra guidelines apply.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Limonene's sensitisation risk arises not from limonene itself but from its autooxidation products (limonene-1,2-epoxide and limonene hydroperoxides) formed on air exposure. fresh limonene has low sensitisation potential, but air-oxidised limonene's hydroperoxide products are potent skin sensitisers. this explains why oxidation-stabilised formulations (with bht or other antioxidants) are required to manage limonene safety.

Linalool
Common Name(s): 3,7-dimethyl-1,6-octadien-3-ol,linalyl alcohol
CAS Number: 78-70-6
DESCRIPTION
What It Does: Provides the most common natural floral-citrus fragrance note with additional anti-inflammatory properties.
Why It's Used: The most abundant fragrance terpene in nature – linalool forms the primary scent character of lavender, responsible for lavender's documented aromatherapy calming effects.
How It Works: Monoterpene alcohol activates gaba-a receptors for anti-anxiety activity (same receptor as benzodiazepines). inhibits glutamate-induced excitotoxicity. antimicrobial via membrane disruption. anti-inflammatory via nf-kb inhibition.
Typically Found In: Virtually all fragranced cosmetics
TECHNICAL DETAILS
Primary Category: Fragrance component – tertiary terpene alcohol
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.001%–3%
SOURCING & ETHICS
Vegan Status: Yes – from lavender, coriander, bergamot
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Eu cosmetics regulation: declared fragrance allergen on label when >0.001% (leave-on) or >0.01% (rinse-off). ifra guidelines apply.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Linalool's gaba-a receptor activation provides a pharmacological basis for lavender aromatherapy's documented anxiolytic effects. the same receptor modulation used by benzodiazepine drugs (such as diazepam) is activated by inhaled linalool vapor, providing receptor-mediated calming without the tolerance and dependence associated with pharmaceutical gaba-a modulators.
