- What it does
- Thickeners & film
- Our take
- Topically it's a texture ingredient with no benefit worth defending, and it's on the pore-clogging lists. The separate food-safety argument about degraded carrageenan and gut inflammation isn't our lane, but it's why you'll see it flagged elsewhere.
- Can it clog pores
- High. We flag it for anyone whose skin congests easily. This flag is for the face only, it does not apply to body, hair or home care.
