This serum is highly effective for managing oily skin, with multiple users reporting a significant reduction in midday shine and overall oil production, making it a go-to for those with combination or oily complexions.
Users find this serum to be a reliable and cost-effective option for improving skin texture, reducing the appearance of blemishes, and brightening the overall complexion, with some noticing positive changes within a week of consistent use.
The serum's lightweight, water-based texture absorbs quickly into the skin, making it suitable for daily routines and layering with other products without feeling heavy or greasy.
The product is praised for its high concentration of active ingredients, particularly niacinamide, at an affordable price point, making it an accessible option for many users seeking effective skincare.
Some users report experiencing a tacky or slightly sticky residue after application, which can sometimes lead to pilling when layering with other skincare products or makeup.
While generally well-tolerated, some users, particularly those with sensitive skin, may experience initial irritation, redness, stinging, or even breakouts when first introducing this high-concentration niacinamide serum into their routine.
The product's claim to treat acne is nuanced; while it can help manage oil and reduce the appearance of blemishes, it is not a direct acne treatment and may not be sufficient for severe acne concerns.

The Ordinary Niacinamide 10% + Zinc 1% is a daily brightening and smoothing serum for blemish-prone skin. It earns an AI Score of 80/100, drawing on 218,630 verified reviews across 5 platforms, making it one of the most extensively reviewed active skincare serums in India. That volume of feedback reflects consistent, long-term use across a wide range of skin types and routines. Reviewers highlight oil control, improved texture, and reduced blemish visibility as the standout results of sustained daily application.
The formula brings together two key actives. Niacinamide at 10% supports pore minimization, brightening, and skin smoothing, while zinc at 1% targets blemishes, blackheads, whiteheads, and acne scars. The texture is lightweight and water-based, absorbing quickly without leaving a greasy residue, which makes layering with other skincare products and SPF straightforward. The serum carries no alcohol, oil, or fragrance, and holds vegan and animal cruelty-free certifications. The 30 ml size suits twice-daily use across a full month without running short.
This serum works best for oily and combination skin types. Reviewers with these skin types report significant reductions in midday shine and overall oil production with regular use, and some notice improvements in blemish appearance within a week of starting. That said, the 10% niacinamide concentration does not suit all skin equally. Users with sensitive skin have reported initial stinging, redness, and in some cases breakouts during the first weeks of use. The serum can also feel slightly tacky after application and may pill under heavy moisturisers or dense sunscreen formulas. It targets blemishes and pore appearance, but it does not function as a direct acne treatment. For severe or persistent acne, it works better as a supporting step alongside other targeted products rather than as a standalone solution.
Prices for this serum run from ₹600 to ₹1002 across 9 sellers in India. At that price point, the combination of a 10% niacinamide concentration, a clean ingredient deck, and an alcohol-free, oil-free, fragrance-free formulation in a 30 ml size delivers strong value for a daily active serum. Flash AI recommends it for anyone with oily, combination, or blemish-prone skin who wants an affordable, well-evidenced option for oil management, pore appearance, and blemish control. Start with once-daily evening use if your skin is on the sensitive side, then build to twice daily. Expect the most reliable results after four or more weeks of consistent application.

Apply this serum morning and evening after cleansing and toning, and before your moisturiser. A few drops cover the full face. Reviewers who used it consistently over several weeks reported the most noticeable improvements in oil control and blemish appearance, so daily use without gaps matters more than frequency alone.
Yes. The product specs list it as suitable for all skin types, and reviewers with oily and combination skin report the most consistent results, including significant reductions in midday shine and overall oil production. Those with dry or normal skin also use it for brightening and texture improvement, though oil control tends to be the most frequently cited benefit.
Niacinamide is the primary active in this serum, listed in the specs at 10% concentration. At this level it supports pore minimization, brightening, and skin smoothing. It works alongside zinc at 1% to address blemishes, blackheads, whiteheads, and acne scars, making it a targeted option for multiple blemish-related concerns within a single daily-use formula.
Some reviewers report noticing positive changes in skin texture and blemish appearance within a week of consistent use. For sustained improvements to pore appearance and oil control, most reviewers who cited specific results had been using the product for four weeks or more. Results vary by skin type, routine, and how consistently the serum is applied.
It can, particularly during the initial introduction period. Some users with sensitive skin have reported stinging, redness, or breakouts when first using this serum. If your skin is reactive, start with once-daily evening application and monitor your skin's response before building to twice-daily use. The formula is free from alcohol, oil, and fragrance, which reduces some of the most common irritant triggers, but the 10% niacinamide concentration is high enough to cause reactions in some users.
Standard moisturisers focus on hydration and do not typically deliver high concentrations of targeted actives. This serum provides niacinamide at 10% and zinc at 1%, both specifically included to address pore appearance, oil control, blemishes, and skin brightness. It works as a treatment step applied before your moisturiser, not as a replacement for it.
This serum sells across 9 sellers in India, with prices starting from ₹600 and reaching up to ₹1002. Comparing prices across multiple retail platforms before purchasing gives you the best chance of finding it at the lower end of that range. The 30 ml size is the standard format.
The serum has a lightweight, water-based texture that absorbs quickly without leaving a greasy residue. Some users report a slightly tacky finish after application, and pilling can occur when layering under heavy moisturisers or certain sunscreen formulas. Applying a thin layer and allowing it to absorb fully before the next product step helps minimise this.
The brand specifies daily morning and evening use, and the product suits all skin types according to its specs. Most reviewers tolerate it well with sustained application. Users with sensitive skin have reported occasional irritation at this concentration, so a gradual introduction starting with once-daily use is a sensible approach. The formula contains no alcohol, oil, or fragrance, which removes several common irritant sources.
The pH of this serum does not appear in the product's publicly available specifications. If pH compatibility matters for your routine, for example when layering with vitamin C or AHA/BHA products, check with the seller or refer to the brand's official documentation before use to confirm compatibility.
