FAQs
Q1. What makes Peltos Niacinamide Sleep Mask different from a standard niacinamide serum?
A1. Where a Niacinamide serum delivers one primary brightening mechanism, the Peltos Niacinamide Sleep Mask combines Niacinamide with Tranexamic Acid, Curcumin, and Gwhite VCE — a four-pathway brightening approach in a single overnight treatment. Niacinamide blocks melanosome transfer between melanocytes and keratinocytes; Tranexamic Acid inhibits UV-triggered melanin production upstream; Curcumin provides antioxidant and anti-inflammatory activity that reduces inflammation-driven PIH; and Gwhite VCE (a stable Vitamin C ether) directly inhibits tyrosinase to reduce melanin synthesis at the enzyme level. The sleep mask format maintains this four-ingredient complex in contact with the skin for 6–8 hours overnight, dramatically outperforming the shorter absorption window of a rinse-off product or thin serum.
Q2. What is Curcumin doing in the Peltos Niacinamide Sleep Mask?
A2. Curcumin — the primary polyphenol from Curcuma longa (turmeric) — has documented anti-inflammatory activity via inhibition of the NF-κB signalling pathway, which is one of the primary drivers of Post-Inflammatory Hyperpigmentation (PIH). When skin is inflamed due to acne, friction, or UV exposure, NF-κB triggers cytokine release that stimulates melanocyte activity — Curcumin suppresses this inflammatory cascade before it reaches the pigmentation response. Modern formulations use stabilised or micro-encapsulated curcumin to overcome the poor water solubility and chemical instability of raw turmeric extract, enabling effective cosmetic delivery.
Q3. What is Gwhite VCE and how does it work in the Niacinamide Sleep Mask?
A3. Gwhite VCE contains a stabilised Vitamin C ether derivative — most likely 3-O-Ethyl Ascorbic Acid (Ethyl Ascorbate), which is significantly more stable than pure Ascorbic Acid and penetrates the skin more efficiently due to its partially lipophilic structure. Like all Vitamin C forms, it inhibits tyrosinase (the rate-limiting enzyme in melanin synthesis) and neutralises UV-generated reactive oxygen species that would otherwise drive oxidative melanin formation. Its inclusion alongside the three other brightening actives means the Sleep Mask addresses melanin production through enzyme inhibition, inflammatory suppression, transfer blockade, and UV-response prevention simultaneously.
Q4. Is Peltos Niacinamide Sleep Mask specifically formulated for PIH-prone Indian skin?
A4. The combination of Niacinamide, Tranexamic Acid, Curcumin, and Vitamin C ether in the Niacinamide Sleep Mask maps directly to the most common causes of PIH in Indian skin (Fitzpatrick types III–VI): acne-related PIH, sun-triggered melasma, and friction-induced dark patches. Indian skin tones have a higher inherent melanocyte activity that amplifies the PIH response to any skin insult. Multi-pathway brightening — which this formula provides — is the clinical approach recommended for PIH in darker skin tones, where aggressive single-ingredient approaches can ironically worsen pigmentation through irritation-triggered melanocyte activation.
Q5. How do I incorporate Peltos Niacinamide Sleep Mask into a routine that already includes Vitamin C and exfoliants?
A5. Apply Niacinamide Sleep Mask as the final step in your evening routine. If you are using a daytime Vitamin C serum (which you should be, for antioxidant protection), continue applying it in the morning — there is no contraindication. If you use a chemical exfoliant (AHA or BHA) in the evening, apply it first, allow it to absorb, and then layer the Sleep Mask over it; the Niacinamide and soothing actives will buffer the post-exfoliation sensitivity. On nights when you apply a prescription retinoid, use the Sleep Mask on alternating nights rather than on top of it.
