Plum's 5% Niacinamide Face Serum is a lightweight, fragrance-free formula designed to target blemishes, uneven skin tone, and rough texture with three active ingredients working together. On Flash AI, this serum earns a score of 80/100, built on 991 verified reviews across 5 platforms. It scores particularly well for skin texture improvement (85) and hydration (80), with consistent reviewer feedback pointing to smoother, more balanced skin after regular use. The formula is 100% vegan and cruelty-free, with a country of origin listed as India and a 24-month shelf life.
Niacinamide at 5% leads this formula, a concentration that dermatological consensus links to blemish reduction, improved skin tone, and greater skin clarity. Rice Water contributes lightweight hydration and supports smoother skin texture over time. The Amino Acid Complex works to maintain the skin's moisture barrier, keeping it resilient and supple after application. The three ingredients come together in a fragrance-free base, making the formula appropriate for daily use by men and women across all skin types, morning and evening.
Users with oily and combination skin benefit most from this serum, thanks to its non-greasy, fast-absorbing texture that layers well under sunscreen and makeup. Beginners to niacinamide actives will find the 5% concentration a gentle entry point, and many reviewers report no irritation even with sensitive skin. Results, however, take time. Reviewers note that consistent use over several weeks is needed before visible improvements in texture and blemish reduction become apparent. A small number of sensitive skin users have reported mild reactions, so a patch test before full application is advisable. If you are targeting deep acne scars, note that reviewers flag limited impact on deeper scarring, though surface blemishes and minor spots do respond with continued use.
Priced between ₹497 and ₹599 across 17 sellers, this serum sits at the accessible end of the niacinamide market without cutting corners on formulation. Flash AI recommends it for users targeting blemishes, uneven tone, and texture concerns, particularly those new to actives or building a budget-conscious routine. The fragrance-free, vegan, and cruelty-free credentials make it a low-risk daily option for both morning and evening routines. If you need faster or more intensive results, or are addressing deep acne scarring specifically, a higher-strength formula may serve you better. For consistent daily niacinamide treatment under ₹600, this serum delivers on its core claims.
"With a Flash AI Score of 80/100, Plum 5% Niacinamide Face Serum With Rice Water & Amino Acid Complex, 30 ml earns its ranking through demonstrated, cross-platform results."

"I just finished using this niacinamide serum, and I have to say, I'm really impressed! The texture is lightweight and absorbs quickly into the skin, which I love. After using it consistently, I've noticed my skin feels smoother, and my pores appear smaller. The scent is very mild, which is a nice touch. I didn't experience any irritation, which is great since I have sensitive skin. Here's an updated review that includes your thoughts on Plum products: "I just finished using this niacinamide serum, and I have to say, I'm really impressed! The texture is lightweight and absorbs quickly into the skin, which I love. After using it consistently, I've noticed my skin feels smoother, and my pores appear smaller. It has also helped with some redness and uneven skin tone I was experiencing."
"I've been using the Plum 5% Niacinamide Face Serum for about 5 months now. Gotta say, it's been a bit of a mixed bag for me. When I first started using it, I noticed that my face would become darker when I used it twice a day. But then I switched to using it only once at night, and thankfully, it doesn't make my skin look dark anymore. In terms of results, it does help in removing blemishes, but not completely. And unfortunately, it didn't live up to its claim of removing acne scars. On t..."
"I was skeptical at first, but this serum has exceeded my expectations. My pores look smaller and my skin tone is more even."
This serum contains 5% Niacinamide, as specified in its formulation. Dermatological consensus considers this concentration effective for targeting blemishes, uneven skin tone, and texture irregularities without being overly aggressive. Reviewers confirm visible improvements in skin smoothness and clarity with consistent use, making the 5% level a practical choice for daily application across most skin types.
Apply this serum after cleansing and toning, before heavier moisturisers or sunscreen, following the general principle of thinnest to thickest consistency. Niacinamide fits into most layering routines without issue. If you use exfoliating acids or other treatment products in the same routine, allow each layer to absorb fully before applying the next. The fragrance-free base reduces the likelihood of irritation when layering.
Yes. The product specifies Day and Night use. Niacinamide does not cause photosensitivity, so morning application is safe when followed by a broad-spectrum sunscreen. Evening use is equally appropriate. Reviewers use it as part of both AM and PM routines without reported issues related to timing.
The serum is formulated for all skin types. Users with oily and combination skin particularly note its non-greasy, fast-absorbing finish that sits well under sunscreen and makeup. The fragrance-free formulation removes a common irritant. While many sensitive skin users find it gentle, a small number have reported mild reactions, so a patch test before full-face application is advisable for reactive skin.
Based on reviewer feedback, consistent use over several weeks is typically needed before visible improvements in skin texture and blemish reduction appear. Some reviewers report noticing a difference within two weeks of regular use, though most accounts point to a longer commitment for meaningful change. Daily application sustained over time delivers better outcomes than intermittent use.
Yes. Reviewers specifically describe this as a beginner-friendly product, citing the 5% concentration as a comfortable starting point for those new to the ingredient. Many users, including those with sensitive skin, report that it is gentle from the first application. As with any new active, a patch test before full-face use is sensible practice.
Niacinamide is not a chemical exfoliant, so it does not trigger the purging phase associated with ingredients like retinols or acids. If you notice new breakouts after introducing this serum, it is more likely a reaction or adjustment response than classic purging. Any persistent skin reaction after continued use should prompt you to reassess your full routine or consult a dermatologist.
The product's specifications and reviewer insights do not address interactions with retinol, vitamin C, or AHA actives specifically. Niacinamide appears in many multi-active routines, but this product's available data does not confirm or test specific combinations. If you use multiple actives, introduce them one at a time to monitor your skin's response, and consult a dermatologist for personalised guidance.
This serum is available across 17 sellers, with prices starting from ₹497. Platforms such as Amazon India, Flipkart, and Nykaa are common retail options, and prices vary by seller and offer.

Rice Water is a key ingredient in this serum, listed alongside Niacinamide and the Amino Acid Complex in the formulation. It contributes lightweight hydration and supports smoother skin texture over time. Reviewers note that the serum hydrates without leaving a greasy or sticky residue, which aligns with rice water's lightweight, non-heavy nature. It works alongside the other ingredients to support overall skin smoothness rather than acting as the primary active.
