How does AIScored compare niacinamide serums?

What should you look for when buying niacinamide serums?
Choosing the right niacinamide serums can be overwhelming with hundreds of options on the UK market. Here are the key factors we analyse when scoring each product:
Active Ingredient Concentration
Position on the INCI list matters. We check whether key actives like retinol, niacinamide, or vitamin C appear high enough in the formula to be effective at clinical concentrations.
Skin Type Compatibility
Not every product suits every skin type. We analyse user reviews for reports of irritation, breakouts, and sensitivity, and flag products that work best for specific skin concerns.
Texture & Formulation
How a product feels on the skin affects daily compliance. We evaluate texture, absorption speed, fragrance, and packaging stability based on real user feedback.
Value per ml
We compare price per millilitre alongside ingredient quality and concentration. A cheaper product with diluted actives may cost more in the long run than a concentrated formula.
How Our Scoring Works
Each product is scored 0-100 across evidence-based categories. An overall score of 80+ indicates a product we'd recommend to most people. Scores of 60-79 are solid choices with some trade-offs, while anything below 60 has significant drawbacks reported by users. Our scores are recalculated regularly as new reviews and ingredient data come in.
Frequently Asked Questions
Where do you get your reviews?
We aggregate publicly available review and product data from retailer pages, communities, and specialist sources. We do not use manufacturer-provided testimonials as evidence.
