That’s *La Roche-Posay Pure Niacinamide 10 Serum*, 30 mL/1 fl oz dropper bottle. *Short summary:* - *Use*: Anti-dark spot, repairing serum for face - *Key actives*: 10% Pure Niacinamide + Hyaluronic Acid + Thermal Spring Water - *Claim*: Targets pigment spots, post-acne marks, and uneven skin tone. Repairing and balancing concentrate - *Texture*: Lightweight, watery-gel serum. Absorbs fast with no stickiness or pilling - *Best for*: All skin types with dark spots, redness, or compromised barrier. Especially good for sensitive or acne-prone skin This is LRP’s answer to niacinamide, but at 10% instead of the 15% in The Ordinary’s version. 10% is the sweet spot clinically shown to fade hyperpigmentation, regulate oil, and calm redness without the irritation risk some people get from 15%. The added hyaluronic acid gives light hydration, and Thermal Spring Water soothes. No fragrance, no alcohol. *How to use*: AM or PM, 3-4 drops on clean skin after toner. It plays well with most actives. Safe to use with the La Roche-Posay Vitamin C10 in the AM if your skin tolerates it, but separate them if you’re sensitive. It’s perfect to buffer your retinol nights: Vitamin C10 in AM, this niacinamide in PM under your retinol or on off nights. *Why this vs The Ordinary Niacinamide 15%*: This is gentler and more elegant. The Ordinary’s 15% is stronger but can sting or cause flushing for some people. If 15% feels too intense, this 10% version is the safer daily driver. If you want maximum brightening and your skin tolerates it, stick with 15%. This won’t pill under your Anthelios UVMune 400 SPF. Great for fading sun spots and post-acne marks in Kampala’s sun without irritating your barrier. You’re building a solid LRP duo: Vitamin C10 for AM antioxidant glow, Niacinamide 10 for PM repair and pigment control.
