How Does The Ordinary Niacinamide 10% + Zinc 1% Serum Work?

The Ordinary Niacinamide 10% + Zinc 1% Serum aims to improve the skin’s appearance through a combination of niacinamide and zinc PCA. These ingredients are said to help balance sebum production, refine skin texture, and reduce visible congestion. The serum’s water-based formula allows for easy absorption, supporting a smoother surface and a more even tone over time ^[1].

Niacinamide is known to support the skin’s natural barrier and may reduce the appearance of enlarged pores and discoloration. Zinc PCA, on the other hand, is used to help calm the skin and maintain oil balance, making it suitable for those prone to excess shine.

According to findings in Scientific Reports, consistent use of niacinamide may improve hydration and strengthen the skin’s defense against external stressors. Together, these effects may contribute to a clearer and more balanced complexion with continued use ^[2].

The Ordinary Niacinamide 10% + Zinc 1% Serum Ingredients

The Ordinary Niacinamide 10% + Zinc 1% Serum contains a combination of key actives designed to help balance oil production, improve texture, and support skin clarity. Below is a closer look at its main ingredients:

Niacinamide (Vitamin B3)

Niacinamide is a form of vitamin B3 that supports the skin barrier, helps reduce moisture loss, and may minimize the appearance of enlarged pores. It is often used in skincare formulations targeting dullness, discoloration, and excess oil. Our WOWMD 10% Niacinamide Serum Review also notes that niacinamide can improve elasticity and even out tone through regular use.

A review in the MDPI Antioxidants Journal explained that topical niacinamide can decrease redness, fine lines, and blotchiness while strengthening the skin barrier and improving hydration levels. This makes it a versatile component in skincare designed to maintain balance and resilience ^[3].

Zinc PCA

Zinc PCA combines zinc, a trace mineral, with pyrrolidone carboxylic acid. It is included in formulations to help regulate sebum production and limit surface bacteria that may contribute to blemishes. This ingredient may also have a soothing effect, helping calm areas prone to irritation or excess shine.

Research published in Current Issues in Molecular Biology reported that zinc-based skincare products may reduce oil buildup and support clearer-looking skin. However, evidence is mixed on its long-term effectiveness for severe acne, suggesting results can differ depending on skin condition ^[4].

Worth Buying

Used this for a year, all my post acne marks are gone. I could see the result within 6 months only. — Stuti

Bad

I’m sorry The Ordinary, I was hoping to love your product, but I just can’t. It made me break out so much and made my skin dry (yes, I used it with a moisturizer). Unfortunately, it’s a no for me. — Rox

Sticky and Flakes

Very bad texture, sticky and it is like soap. As I spread, it becomes white. After absorption and a few layer after, it always flakes, with just 2 drops for my face. So I can’t use it in the morning and go outside with these flakes. I regret my purchase. — Kermahe
