How to mix niacinamide powder with cleanser

Can you add niacinamide to your usual cleanser?

Niacinamide is available in cleansers, but choosing a finished formula is different from adding powder to your existing face wash. A cleanser can contain niacinamide, but an ingredient list is not an invitation to finish the formulation yourself. An exact mixing amount needs directions for your particular powder, not a general recommendation for the ingredient.12

How to use niacinamide without changing your cleanser

1. 1Wash with a mild cleanser before applying your treatment products.
2. 2Apply a finished niacinamide product using its own directions. For example, The Ordinary's morning routine places Niacinamide 10% + Zinc 1% serum after cleansing.
3. 3Apply moisturizer, then finish your morning routine with sunscreen.

Using a finished niacinamide serum keeps cleansing and treatment separate, without giving your bathroom a formulation department.2

What strength should you choose?

Most niacinamide skincare products contain 5% or less, although concentrations vary. Start slowly with a low concentration if your skin is sensitive. General guidance allows niacinamide once or twice daily after gentle cleansing; your finished product's directions should determine its place in the routine. Avoid stacking several niacinamide products at once.1

What results can you expect?

Niacinamide can support the skin barrier, which helps skin retain moisture, and reduce facial oil production. A 2% niacinamide moisturizer reduced oiliness over four to six weeks. Separately, a 5% topical niacinamide treatment used twice daily improved freckles and sun spots in as little as four weeks. These are useful expectations for finished topical treatments, not a timetable for homemade cleanser mixtures.34

For acne, niacinamide is a possible supporting ingredient rather than a reason to replace prescribed treatment. Clinical support for niacinamide is less robust than for benzoyl peroxide or azelaic acid.5

How do you mix niacinamide powder with serum?

Use the powder's specific instructions to choose the serum and mixing amount. General advice to use niacinamide alongside hyaluronic acid or other skincare ingredients is not a powder recipe. A finished niacinamide serum avoids having to choose the amount yourself.12

How do you mix niacinamide powder with cream?

A finished niacinamide serum can be combined with moisturizer and applied to the face and neck. That is not a measurement guide for loose powder. For powder, use its own directions; otherwise, choose a cream that already contains niacinamide.1

How do you mix niacinamide powder with water?

Niacinamide is water soluble, meaning it dissolves in water. That property alone does not give you an application strength or a mixing amount. Follow a powder product's directions rather than treating plain water as a complete skincare recipe.26

What if niacinamide irritates your skin?

Niacinamide is generally gentle, but itching, mild burning, redness and allergic reactions can occur. Patch test a small amount on your forearm and wait 24 hours before wider use. Stop using a product that causes irritation. Seek medical care for a suspected allergic reaction or an ongoing medical skin concern.14
