It is suitable for all skin types according to current product documentation.

The serum is designed for topical facial use and is normally applied after cleansing and before heavier creams or oils. The manufacturer permits morning and evening use and advises applying only a few drops at a time. Patch testing is recommended before regular use.

Maintenance and Care

Keep the container securely closed when the serum is not being used. Store it under normal cosmetic-storage conditions away from excessive heat and direct sunlight.

Keep the dropper and bottle opening clean to reduce contamination. Avoid touching the dropper directly against the skin or other surfaces when dispensing the serum.

Use the product only on intact skin. The manufacturer recommends applying a few drops rather than dispensing large quantities, which also reduces unnecessary product buildup when layering other skincare products.

Before disposing of the packaging, empty the container and separate the dropper or closure where local recycling requirements call for separation. Packaging recyclability varies by local collection program.

Safety Information

• Use only as directed on unbroken skin.
• Patch testing before regular use is advised.
• If redness, burning, itching, blistering, or significant irritation develops during patch testing, do not use the product.
• If irritation develops during normal use, rinse the product off and discontinue use.
• Keep the product out of reach of children.
• Avoid direct contact with the eyes.
• The manufacturer currently advises against using the serum in the same routine as direct or indirect vitamin C formulations.
• The serum is a cosmetic skincare product and is not an acne medication.

Technical Specifications

Ingredients

The current manufacturer ingredient list includes water, niacinamide, pentylene glycol, zinc PCA, dimethyl isosorbide, tamarind seed gum, xanthan gum, Isoceteth-20, ethoxydiglycol, phenoxyethanol, and chlorphenesin.

Cosmetic formulations can be revised over time or vary by region. The ingredient list printed on the physical package should therefore be checked when ingredient sensitivity or allergy information is important.

Product History

Niacinamide 10% + Zinc 1% has been part of The Ordinary’s ingredient-focused skincare range since the brand’s early years. The formulation became one of the brand’s established water-based facial serums and has remained available in multiple bottle sizes.

The product is currently offered in 30 mL and 60 mL formats. Its core naming continues to emphasize the concentrations of its two highlighted ingredients: 10% niacinamide and 1% zinc.

The manufacturer periodically updates formulation information, packaging, testing claims, and compatibility guidance. Older packaging or regional versions may therefore differ slightly from current documentation even when the product name remains unchanged.

Compatibility

The serum is intended to fit into a conventional facial skincare routine after cleansing. Water-based serums are normally applied before heavier creams, oils, and similar occlusive products.

The manufacturer currently recommends separating Niacinamide 10% + Zinc 1% from direct and indirect vitamin C formulations rather than applying them within the same skincare routine.

Compatibility with other skincare products can depend on formulation strength, skin sensitivity, and the number of active products being layered. Introducing several new active formulations simultaneously can make it harder to identify the cause of irritation.

The serum does not require electrical equipment, applicators, cartridges, batteries, or proprietary accessories. It is applied directly from the bottle using the supplied dropper.

• Review the physical ingredient list if allergies or ingredient sensitivities are a concern.
• Patch testing is advised before routine facial application.
• The 10% niacinamide concentration may feel stronger than lower-concentration niacinamide formulas for some users.
• The product should be applied only to intact skin.
• Current manufacturer guidance separates this serum from direct and indirect vitamin C products in the same routine.

Customer Feedback Summary

This section summarizes recurring themes reported in publicly available customer reviews and skincare discussions. These observations are subjective user experiences rather than verified technical specifications or medical evidence.

Oil control is one of the most frequently reported positive themes. Many users with combination or oily skin describe reduced visible shine and consider the serum easy to incorporate into a basic daily routine.

Texture and pore appearance are also commonly discussed. Some users report that their skin looks smoother or more even after continued use, while others notice little visible change.

The water-based texture receives mixed feedback. Many users describe the serum as lightweight, but pilling is a recurring limitation when too much product is applied or when it is layered beneath several other formulations.

Skin tolerance varies. Some users report comfortable daily use, while others describe temporary dryness, stinging, redness, small bumps, or breakouts after introducing the serum. These reactions do not occur uniformly and should not be interpreted as expected results for every user.

Some customers reduce application frequency when the 10% niacinamide concentration feels too strong. Others report using the serum consistently in both morning and evening routines without notable irritation.

Overall public feedback shows substantial variation based on skin type, sensitivity, application amount, and the other products used in the same routine.
