Niacinamide is a beneficial ingredient in moisturizers. It can help improve skin hydration, reduce redness, and minimize the appearance of pores, making it a popular choice for various skin types.

Avoid using high concentrations of vitamin C (L-Ascorbic Acid) at the same time as niacinamide, as they can potentially neutralize each other. If using both, apply them at different times of the day, such as vitamin C in the morning and niacinamide at night.

Hyaluronic acid and niacinamide serve different purposes and are both beneficial. Hyaluronic acid primarily focuses on hydration, while niacinamide offers a broader range of benefits like oil control and reduced redness. They can be used together for enhanced skin benefits.

Some individuals may experience mild irritation, redness, or dryness when first using niacinamide, especially at higher concentrations. It's recommended to start with a low concentration and gradually increase it as tolerated, and to patch test before full application.
