Expert Analysis · Honest Reviews · Real Results
1.🔍The Great Primer Divide

The new formula dropped — and the beauty internet is at war. Five-star raves vs. one-star rants. What’s the real story?

The original was a blurring legend. This reformulation? It’s a different beast entirely — and the texture is the first dead giveaway.

2.🧲The Magnet Claim

One/Size‘s Secure the Blur is $38. The promise? A “magnetizing” primer that grips makeup for 16 hours. Bold.

3.⚗️What’s Inside Now

They swapped out silicones for more skincare ingredients. It’s a hybrid now. The hero is a tri-peptide complex for “lifting.”

  • Tri-Peptide Complex: For a tightened, ‘snatched’ feel
  • Niacinamide: For oil control and smoothing
  • Squalane: A hint of hydration
  • Kaolin Clay: Absorbs excess sebum

4.💬Skin Feel Test

Old one: silky silicone slip. New one: a thicker, putty-like texture. It tugs — you have to press and pat, not glide.

Week 3: My makeup definitely lasted. But that “snatched” peptide feeling? It’s real. Felt like a light workout for my cheeks.

💡

One Thing: Warm a pea-sized amount between your fingers first. Applies way smoother.

5.📊The Real Results

Blurring? Still excellent — pores vanished. The 16-hour hold? My makeup looked fresh for a full workday. But the finish is less matte, more natural.

6.So, Is It Worth It?

It’s not the same primer. But for a long-wearing, pore-blurring grip, it’s still a top contender — just for a different crowd.

Where to Buy: Sephora. Try the travel size first — the texture is polarizing.
