Insight Cosmetics 10% Niacinamide Vitamin C Face Serum, 30ml

If your skin is oily, your pores are visible, and your face looks shiny by 11 AM, you need Niacinamide. It is the one skincare active that Indian oily skin responds to almost immediately. The Insight 10% Niacinamide + Vitamin C Serum combines a potent 10 percent Niacinamide concentration with Vitamin C for a serum that controls oil, shrinks the appearance of pores, and brightens your complexion all in one step. Insight Cosmetics, one of India's fastest growing affordable beauty brands, formulated this specifically for Indian oily skin that battles shine, large pores, and dullness simultaneously.

Niacinamide (Vitamin B3) at 10% is the clinical sweet spot where oil control and pore reduction are most effective without irritation. The added Vitamin C provides antioxidant protection and brightening that Niacinamide alone cannot deliver. Together, they give you skin that is less oily, less porous, and more even toned. This is the best niacinamide serum for oily skin India has at this price because it combines two power actives in the right concentrations. Most competing niacinamide serums use 5% or lower, which takes much longer to show visible pore reduction. The 10 percent concentration here means faster results. Among niacinamide serums in India, this niacinamide vitamin c combination addresses the three most common oily skin complaints in one bottle. Free from parabens, ethically made. Prime your skin before foundation with a pore minimizing primer over this serum for a double pore-blurring effect that lasts all day.

Skin Concern Guide

How this serum addresses different oily skin problems.

Excess Oil and Shine: The 10% Niacinamide regulates sebum at the source. Most users notice reduced shine within 1 to 2 weeks of consistent use.

Large Visible Pores: Niacinamide tightens pore appearance by improving skin elasticity. Visible pore reduction typically starts at week 2 to 3.

Dull, Uneven Tone: The Vitamin C component brightens and evens out the complexion. Improvement in skin brightness is usually noticeable within 2 to 3 weeks.

1. Is this the best niacinamide serum for oily skin in India?

At serum with a potent 10% Niacinamide concentration plus added Vitamin C, it is among the most effective niacinamide serums for oily skin in India. Most competing serums use 5% or lower Niacinamide, which takes significantly longer to show visible oil control and pore reduction results. Build on the oil control results with a translucent setting powder for oily skin to lock in matteness across the full face after the serum absorbs.

2. What does 10 percent niacinamide actually do for pores?

At 10%, Niacinamide regulates your skin's oil production and improves the elasticity of the pore walls. When your skin produces less oil, pores are no longer stretched by excess sebum and appear smaller. The elasticity improvement means pores hold their tighter shape better. Most users see visible pore reduction within 2 to 3 weeks of consistent daily use. Visually blur pores on the surface with a pore filling primer while the serum works long term underneath.

3. Can I use this niacinamide serum with retinol or salicylic acid?

Niacinamide is one of the most compatible actives in skincare. You can safely use it alongside retinol, salicylic acid, hyaluronic acid, and most other actives. If using with the retinol anti ageing serum, apply Niacinamide in the morning and Retinol at night for the best results without overwhelming your skin.

4. Will this make my oily skin less oily?

Yes, and this is the primary benefit of Niacinamide for oily skin. At 10% concentration, it regulates sebum production at the cellular level. Within 1 to 2 weeks, most users notice their T zone is less shiny and their skin feels less greasy by midday. The effect builds with continued use. Apply over a hydrating alpha arbutin serum at night to add moisture back to skin that oily skin treatments can sometimes over-dry.

5. Does the Vitamin C in this serum cause any sensitivity to sunlight?

The small amount of Vitamin C in this formula works primarily as an antioxidant and brightener. While sunscreen is always recommended with any active skincare, the Vitamin C concentration here is not high enough to cause significant photosensitivity. That said, daily SPF 30 or higher is good practice regardless. Use an invisible daily sunscreen every morning as your non-negotiable final skincare step over this serum.
