Description
La Roche-Posay Pure Niacinamide Serum is a concentrated gel serum designed to care for skin suffering from hyperpigmentation, dark spots, acne marks, uneven skin tone, and dullness.

- Massage or gently pat until the serum is absorbed.
- Follow with a suitable moisturizing cream for your skin type.
- Can be used morning and/or evening.
- A small amount can be used on spots on the hands when needed.
- In the morning, complete the routine with a broad-spectrum sunscreen.
Usage Tips from Beauty Time:
- The Beauty Time team recommends applying the serum after cleansing and before moisturizing cream so the skin can benefit from its high concentration of Niacinamide.
- For dark spots, apply the serum over the entire area instead of only on the spot to help improve overall tone evenness.
- If your skin is sensitive or not used to exfoliating formulas, start with once in the evening or every other day, then gradually increase use according to tolerance.
- Although HEPES provides gentle exfoliation, avoid overusing several strong exfoliants in the same routine if signs of dryness or irritation appear.
- If you use retinol or strong acids, they can be applied at different times of the day or on different days when the skin is sensitive.
- For dry skin, follow the serum immediately with a cream that supports the skin barrier to help lock in moisture.
- For oily skin and skin prone to breakouts, choose a lightweight, non-heavy moisturizer after the serum.
- Avoid relying on pigmentation serum without sun protection; daily sunscreen is one of the most important steps to help prevent the appearance of spots from increasing.
- On the hands, reapply sunscreen during continuous sun exposure to help maintain the results of the tone-evening routine.
- If persistent stinging, redness, or noticeable dryness appears, reduce the frequency of use and temporarily focus on hydration and supporting the skin barrier.
