Niacinamide: The One Ingredient Indian Skin Has Been Waiting For

Niacinamide works on pigmentation, pores, sebum and barrier — simultaneously, gently, and with remarkable evidence behind it. Here is everything you need to know.

In the last decade, niacinamide has become one of the most discussed skincare ingredients in the world — and for good reason. Unlike many trend ingredients that arrive with bold claims and depart with lawsuits, niacinamide has remained because the evidence for it keeps accumulating.

What is Niacinamide?

Niacinamide is a form of Vitamin B3 (niacin). It is water-soluble, stable in formulation, and has a broad range of mechanisms that make it unusually effective across multiple skin concerns simultaneously. It is not an acid. It does not exfoliate. It works through cellular pathways.

Niacinamide is one of the few ingredients that is both a treatment and a barrier support agent — it works on the concern while protecting the skin from the inside.

The Five Things Niacinamide Does

• Reduces melanin transfer between melanocytes and keratinocytes — resulting in gradual, even lightening of dark spots

• Regulates sebaceous activity — producing less surface oil without triggering rebound oiliness

• Increases ceramide synthesis — strengthening the skin's lipid barrier over time

• Reduces inflammatory markers — useful for acne-prone and sensitive skin

• Minimises the appearance of pores — by supporting skin structure around follicles

What Concentration Should You Use?

5% is the evidence-backed concentration for sebum regulation and brightening. 10% is increasingly used for acne and faster pigmentation results. Some dermatologists recommend starting at 5% and moving to 10% once tolerance is established. Above 10%, the risk of redness and sensitivity increases without proportional benefit.

The Vitamin C Myth

For years, the internet insisted that Niacinamide and Vitamin C should never be used together — the claim being that they form nicotinic acid which causes flushing. This has been thoroughly debunked. The reaction requires high temperatures well above what skin ever reaches, and the quantities involved would need to be far higher than any skincare formulation delivers. Use both confidently, ideally with Vitamin C in the morning and Niacinamide in your full routine.

Who Should Use It?

Almost everyone. Niacinamide is one of the most universally well-tolerated actives in skincare. It is appropriate for dry, oily, combination, and sensitive skin. It is safe in pregnancy (check with your doctor, but the general consensus supports it). It is non-photosensitising, meaning you do not need to restrict it to evenings.
