Ingredient Intelligence

The Ingredient Dermatologists Recommend More Than Any Other

Niacinamide (Vitamin B3) has decades of clinical literature supporting its multi-function skin benefits — yet most formulas contain 2–5% because it's cheaper. We give you the clinically effective 10% concentration, paired with Zinc PCA for sebum control and Panthenol for deep barrier repair.

Niacinamide 10%
Vitamin B3 — The Multi-Tasker
The most studied dermatologist-recommended skin active. At 10%, it simultaneously refines pores, evens tone, regulates oil, builds the barrier, and reduces inflammation.
Zinc PCA 1%
The Sebum Calibrator
Communicates directly with sebaceous glands, normalising oil production without over-drying — results last all day. Prevents acne-causing bacterial growth.
Hyaluronic Acid 1%
Multi-Weight Hydration
Holds 1,000× its weight in water. Large molecules hydrate the surface; smaller fragments penetrate deeper layers for lasting plumpness and comfort.
D-Panthenol 2%
Vitamin B5 — The Soother
Penetrates deep into the skin to soothe, repair, and lock in moisture. Particularly valuable for post-acne skin and rosacea-prone skin types.
10%
Clinical studies confirm that 10% Niacinamide delivers statistically significant pore reduction and oil control results

My pores around my nose were my biggest insecurity. After 3 weeks of using this, they've visibly shrunk. My skin looks smoother, less oily, and I don't need to blot by midday anymore. Absolutely love it!

I have combination skin with really oily T-zone. This serum has genuinely changed my skin texture. Pores look tighter, oil is under control, and my post-acne marks are fading week by week. The 50ml bottle is amazing value too!

Been using with the Vitamin C serum — Niacinamide at night, Vitamin C in the morning. My skin has never looked this good. Pores refined, tone evened out, and my barrier feels so much stronger. Best combo ever!

What Makes Eternal Bright Different

In a market flooded with watered-down serums and inflated claims, here's why thousands of Indians trust Eternal Bright.

🎯
Clinically Active Concentrations
We use actives at concentrations that clinical studies show actually work — Niacinamide 10% + Zinc PCA 1% — not 2% token amounts that look good on labels.
🧪
Dermatologist-Designed Formulas
Our serums are formulated with dermatologists who understand Indian skin types, humidity, and UV exposure — not generic recipes.
📏
50ml — India's Best Value
Most brands give you 30ml. We give you 50ml. That's 3–4 months of daily use — 40% more product for a fraction of premium brand pricing.
🌱
Clean, Conscious Formulation
No parabens, no sulfates, no harmful fillers. Cruelty-free. Every ingredient has a reason to be there — and we can tell you exactly why.

Frequently Asked Questions

Yes — it's one of the most well-tolerated actives in skincare. Daily AM and PM use is not only safe but recommended for best results. Its non-irritating profile makes it ideal for twice-daily use on all skin types.
Yes to both. The old claim that Niacinamide cancels Vitamin C has been scientifically disproven. For AM: apply Vitamin C first, then layer Niacinamide after 60 seconds. For PM: Niacinamide can be used alongside Retinol to reduce retinol-induced redness.
This is arguably the most important serum for oily, acne-prone skin. The Niacinamide 10% + Zinc PCA combination directly addresses root causes — excess sebum production and bacterial inflammation — while fading the post-acne marks they leave behind.
No — this formula is completely non-comedogenic. The entire formulation is specifically designed to unclog and refine pores, not block them. Every ingredient has a confirmed comedogenic rating of zero.
Our 50ml bottle lasts 3–4 months with twice-daily use (3–4 drops per application AM + PM). That's nearly double what most brands offer at the same price point.
