On The Ordinary, ingredient transparency, and what niacinamide actually does

Looking for it? The Ordinary Niacinamide 10% + Zinc 1%

Beauty

the serum i tell literally everyone about

Someone whose skin I admired mentioned this serum almost as an afterthought. Not a recommendation, just something she used. That was enough for me to try it.

The first two weeks were quiet. Skin looked slightly less congested. Not dramatically, not overnight, but in the way you notice on a Tuesday morning that something is different and you cannot immediately name it. The texture had evened out. The oiliness through the afternoon had calmed.

The Ordinary Niacinamide 10% + Zinc 1% is built on a simple premise. High concentration of a well-studied ingredient, no fragrance, no filler, transparent label. Niacinamide at 10% regulates sebum, minimizes pore appearance, brightens uneven tone, and strengthens the skin barrier. The zinc PCA controls oil specifically. It is a water-based serum that absorbs in seconds and layers under anything.

By month two, I had given the link to four people unprompted. Over 100,000 units move through Amazon in a single month. That number is not marketing. It is the product working.

This is the niacinamide serum I use → The Ordinary Niacinamide 10% + Zinc 1%

The Ordinary Niacinamide 10% + Zinc 1% — under $10, 100,000 units sold monthly, and the one skincare product I would tell anyone to start with before spending more on anything else.
