I put this clean, no-pore-clogging serum to a month-long test against stubborn chin blackheads — here’s what actually happened week by week.

1.🔬Chin Check, 30 Days Later

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.

2.📸What’s In The Dropper

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.

1

Powder + Liquid Format

You activate the powder under the cap by pressing down — feels like a science experiment for adults

2

Use Within 30 Days

Once mixed, it expires fast. Forces you to actually commit.

3

Targeted Application

Not a full-face thing. You dab it on problem zones only.

3.🧴The Ingredient Nerd List

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

4.📉Week By Week Reality

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.

💡

One Thing: Mix it into a water-based gel moisturizer, not cream. Creams buffer the active ingredients too much and you lose the punch.

5.💡The Honest Verdict

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.

Worth it?
$48 for a month’s supply. Cheaper than a facial, but you have to be consistent.

6.👩‍🔬Final Call

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

7.5/10
Good for maintenance, not miracles
