The Ordinary Niacinamide 10% + Zinc 1% Serum 30ml – High-Strength Vitamin & Mineral Blemish Formula

The Ordinary Niacinamide 10% + Zinc 1% Serum 30ml – High-Strength Vitamin & Mineral Blemish Formula | Pores, Oil Control & Even Skin Tone

Some products change the skincare industry. The Ordinary Niacinamide 10% + Zinc 1% is one of them. When DECIEM launched The Ordinary with the explicit mission of making high-quality, clinical skincare ingredients accessible to everyone at honest prices, this serum became the product that defined the brand — and arguably shifted the direction of the entire mainstream skincare market.

What makes it so effective and so endlessly recommended is not complexity. It is exactly the opposite: a focused, high-concentration, two-ingredient formula that does what it says on the label.

💊 Niacinamide 10% — High-Strength Vitamin B3 at Proven Concentration

At 10% concentration, Niacinamide is at the upper boundary of what dermatologists consider clinically effective for topical application — delivering the full range of its well-documented cosmetic benefits at meaningful potency.

Pore appearance: Niacinamide at 10% has been shown in multiple clinical studies to help visibly reduce the appearance of enlarged pores with consistent daily use — particularly in individuals with oily and combination skin where sebum overproduction leads to pore dilation.

Skin tone evening: Niacinamide inhibits the transfer of melanin-containing vesicles (melanosomes) from melanocytes to keratinocytes — the cellular mechanism responsible for surface pigmentation. By disrupting this transfer process, Niacinamide helps visibly reduce dark spots, post-acne marks, and hyperpigmentation over time.

Sebum regulation: sebum overproduction is the root cause of oily skin, congested pores, and acne breakouts. Niacinamide has been shown to help normalize sebum production — reducing surface shine and the likelihood of pore blockage.

Barrier support: Niacinamide stimulates ceramide synthesis in the skin — strengthening the moisture barrier, reducing transepidermal water loss, and improving the skin’s overall tolerance and resilience.

🔬 Zinc 1% (Zinc PCA) — The Perfect Partner

Zinc PCA (pyrrolidone carboxylic acid) is the specific form of zinc used in The Ordinary’s formula — a highly skin-compatible zinc salt with superior absorption characteristics compared to standard zinc compounds.

Zinc PCA is associated with supporting normal sebaceous gland activity, contributing to the serum’s oil-regulating effect alongside Niacinamide. The combination of both actives in a single formula creates a synergistic effect on sebum control and skin clarity that neither ingredient delivers quite as effectively alone.
