The Ordinary Niacinamide 10% + Zinc 1% is one of the most famous budget serums ever made. It’s cheap, it’s everywhere, and it promises to reduce the look of blemishes, congestion and oiliness.
Niacinamide (vitamin B3) is a well-studied ingredient that helps with oil control, redness, uneven tone and barrier function. Zinc PCA is added to help balance oil. But is it right for you? Here’s what to expect.

What it does well
- Reduces the look of oiliness over several weeks of consistent use
- Helps pores look smaller by keeping them clearer
- Fades post-acne marks and evens out skin tone over time
- Very affordable, especially compared with similar serums
The downsides
- Pilling: it can ball up under some moisturizers and sunscreens, especially silicone-heavy ones. Use a small amount and let it dry fully.
- Irritation: 10% is a high concentration. Some people get redness, itching or breakouts. If that happens, try a lower-strength niacinamide.
- Tacky feel: it dries a little sticky before your moisturizer goes on.
How to use it
- Cleanse your face and pat dry.
- Apply 2 to 3 drops and press into your skin.
- Wait a minute until it’s absorbed.
- Follow with moisturizer, and sunscreen in the morning.
It plays well with most ingredients, including retinol and hyaluronic acid. If you use a strong vitamin C serum, many people prefer to use niacinamide at night to keep their routine simple.
Alternatives
- Gentler: a 5% niacinamide product, such as The Ordinary’s Niacinamide 5% Face and Body Emulsion or The Inkey List Niacinamide.
- In a moisturizer: CeraVe PM Facial Moisturizing Lotion contains niacinamide, so you get the benefits in one step.

FAQ
How long does niacinamide take to work?
Most people notice less shine within two to four weeks, and more even tone after eight to twelve weeks.
Can niacinamide cause breakouts?
It’s not known to clog pores, but some people react to high concentrations with redness or bumps. If you break out after starting it, stop and try a lower strength.

The bottom line
For oily and blemish-prone skin, The Ordinary Niacinamide 10% + Zinc 1% is an excellent, affordable serum. Use a small amount to avoid pilling, and switch to a 5% option if your skin is sensitive.
