I spent a month putting Odacité’s Caïa serum on my chin every single night. Not because I love routine — because those tiny blackheads refused to leave after a decade of trying.
The real test? My chin is oily but flakes in winter. Most pore stuff turns me into a lizard.
It’s a $48 serum concentrate — you mix a few drops into your moisturizer or toner. Not a stand-alone product. The brand claims it “visibly reduces blackheads in 7 days.” I rolled my eyes so hard.
Powder + Liquid Format
You activate the powder under the cap by pressing down — feels like a science experiment for adults
Use Within 30 Days
Once mixed, it expires fast. Forces you to actually commit.
Targeted Application
Not a full-face thing. You dab it on problem zones only.

Three actives doing actual work. No trendy filler oils that clog your pores while claiming to unclog them. The blackhead-fighting lineup is lean and mean.
- Salicylic Acid: Exfoliates inside the pore — not just the surface
- Green Tea Extract: Calms the redness that salicylic acid causes
- Kaolin Clay: Sucks out oil without stripping your moisture barrier dry

First touch: watery, slightly gritty from the clay. Dries in maybe 15 seconds. No sticky residue — I forgot I applied it after a minute.
Week 2: My chin looked… worse. More tiny bumps surfaced. I almost quit. Week 3 is when they actually flattened. Week 4? Chin is smoother than it’s been since I was 15. The surprise — it didn’t dry out the flaky patches around my mouth.

Chin blackheads reduced by maybe 70%. The deep, stubborn ones shrank but didn’t vanish. The surface ones? Gone by week 3. I still get new ones forming, just smaller and less angry.

I’d buy it again for maintenance, but I wouldn’t expect miracles. It’s a solid tool, not a magic eraser.
