Real Barrier Control-T Acid Pore Clay Pack

Ingredient analysis and how the ad lines read

Read on 2026-09-21

What is this product?

A fast wash-off clay pack built on kaolin, diatomaceous earth and red bean powder with trace-level acids, aimed at oily pores and short 2 to 5 minute use. The acids are present at very low concentrations, so this works mainly as a clay absorbent rather than a chemical exfoliant.

What makes it different?

The formula puts kaolin at position 4 and diatomaceous earth at position 6, with red bean powder at position 8, so the absorbent clay base genuinely leads the list. Citric acid and gluconolactone are each disclosed at 500 ppm and salicylic acid at only 1,000 ppb, which is far below typical leave-on exfoliant levels. Hyaluronic acid variants and amino acids sit in the later half, softening the drying feel of the clay. Patchouli and Artemisia Vulgaris oils are present, which sensitive or fragrance-avoiding users may want to note.
