Ingrown Hair Oil

The bumps that keep coming back.

You know the ones. The red dots along the bikini line three days after a wax. The angry patch on your neck that turns up in every work photo. The thing you've quietly organised weekends around.

This is the oil for those.

What is it? An anhydrous ingrown hair oil — no water, no alcohol, no preservative system, nine ingredients — formulated by a cosmetic chemist in New Zealand for ingrown hairs and razor bumps.

What does it do? Softens the hair shaft so it grows out instead of curling back into your skin, and keeps the follicle clear so it has somewhere to go. That's most of what this oil does. No mystery complex, no proprietary blend with a trademark symbol.

Why is it an oil? Because its hero active is an oil-phase lipid and can't be carried any other way. Not because oil is what this category looks like. A follicle is a lipid-rich environment, and an anhydrous base delivers oil-loving actives into it better than a water-based one does.

What's the active? Biome Oléoactif — a COSMOS-certified lipid active carried in oat oil, built from fatty acids captured from a wild extremophilic microorganism. The whole category reaches for antibacterials, tea tree almost always. This one goes the other way: it's chosen to support the follicle's existing microbial ecology rather than attack it. That description comes from the supplier's own data, and we've asked to see the study design and haven't got it yet — so we can't tell you whether people were involved, and we're not going to imply it. There's also mandelic acid at 0.3%, in for its antibacterial contribution, which is well established against bacteria in a dish. 0.3% is not an exfoliating dose and we'd rather say so than let you assume.

What does it feel like? It sinks in. It's anhydrous and alcohol-free, which is the reason it's designed to be comfortable on skin you shaved ten minutes ago or waxed this morning. It won't wreck your sheets.

How long does it take? Two to three weeks of daily use before you can fairly judge it. Some people see it sooner. We're telling you the real number because the alternative is you giving up on Thursday.

Where can you use it? Bikini line. Underarms. Legs. Neck. Jawline. Anywhere hair comes back angry. Same bottle whoever you are.

What this oil has not been shown to do

We have not tested this formula on people for efficacy. There is no consumer assessment behind it, no instrumental measure and no clinical trial, so you won't see the words "clinically proven" here.

It hasn't been shown to prevent ingrown hairs from forming. It won't clear an infected lesion. It isn't a hair removal product and it has nothing to do with how much hair you grow.

What sits behind it is the reasoning for every ingredient, published in full, with the evidence level attached. Read that here. A consumer assessment on the finished oil is the first study we intend to run, and it would change this paragraph.

50 ml — the one that lasts. Roller ball, amber glass. $49
10 ml — the one that fits in a bag. $19

How to use

Roll it on clean, dry skin once a day — best straight after a shower, while your skin's still warm. Use it on shave days and the days between; consistency is the entire trick. Exfoliate twice a week if you can. A flannel is fine. You don't need to buy anything else.

When not to use it

If a bump is hot, swollen, spreading or painful, that's not an ingrown hair having a bad day — that's something for a doctor. Go see one. We'll be here.

Not on broken skin. External use only.
