We recommend building up your skin's tolerance before gradually increasing the niacinamide concentration of your product.Q: What is the difference in concentration? Which concentration is more suitable?A: Niacinamide at 5% is the optimal concentration for effectiveness and safety for most consumers. At concentrations higher than 5%, niacinamide is not fully absorbed by the skin. Concentrations lower than 5% have the same skincare benefits, but are more gentle.Q: Can I use it during the day and at night, and do I need to avoid light?A: Niacinamide is a water-soluble vitamin that is stable in light and air, so there is no need to avoid light, and it is more effective when used in the morning and evening.
