Myth Busted

We put the viral serum to the test to see if the dreaded ‘purge’ is a myth or a must-endure reality.

Expert Analysis · Honest Reviews · Real Results

1.🧪The Purge Panic

My skin looked worse. Tiny bumps everywhere. Was this the infamous niacinamide purge?

It’s not a real thing. Purging only happens with actives that increase cell turnover — like retinoids or acids. Niacinamide isn’t one of them.

2.🤔The Viral Bottle

The Ordinary’s Niacinamide 10% + Zinc 1%. $5.90. The claim? Clearer, balanced skin. The reality? A masterclass in managing expectations.

Almost suspiciously cheap.

TikTok made it a breakout star — literally.

No-frills, borderline clinical.

3.⚠️What’s Inside

It’s a simple, potent list. The 10% niacinamide is high — most studies use 5%. That’s the key.

4.🔍Skin Feel Test

Texture is slick — like a thin glue. Dries down fast. Leaves a faint, tacky film. Not silky.

Week 2: The tiny bumps? That was irritation. My skin was throwing a fit. I dialed back to every other day. It listened.

💡

One Thing: Apply to bone-dry skin. Damp skin makes it pill like crazy.

5.✅The Real Results

After a month, my T-zone was noticeably less shiny by 2 PM. Pores looked tighter. Zero effect on existing breakouts.
