Simple's 10% Niacinamide Booster Serum is a transparently formulated product with good evidence for its carefully worded claims, but consumers should be aware of amplified promises made by third-party retailers.
₹799 • Analysed 18 July 2026
Actives like this can raise sun sensitivity, which India's high year-round UV makes significant, so pairing with a daytime SPF is important; the lighter the vehicle, the better it tends to wear in heat and humidity. The MRP of Rs.799 is consistent across all major platforms. However, the product is frequently available at significant discounts (around 30%) on e-commerce sites like Nykaa and Amazon, making its effective price lower and offering good value for a 10% Niacinamide serum. 4 marketing claims could draw ASCI scrutiny under India's advertising code; the ingredient list is the more reliable guide.
