Tetra Oleum™ Cleansing Oil

OIL-TO-MILK · WHOLE BODY · REMOVES MAKEUP
The oil that turns to milk and takes the day off.

Most cleansers get skin clean by stripping it. Tetra Oleum goes on as an oil, turns to a light milk when water hits it, and rinses clean — makeup, sunscreen, sweat and the day's grime gone, your skin's own lipids left where they belong. One cleanser, face to feet. Step 1 of the routine.

Fragrance Free

How this supports longevity: cleanses with oils so the barrier — skin's first job — stays intact from day one.

Is it for your skin?

Anyone whose skin feels tight after a shower. Anyone who wants one cleanser for face and body — including taking off makeup and sunscreen. Dry arms and legs. Skin that reacts to foaming washes.

The science

Sulfate cleansers remove dirt by removing lipids — including yours. Tetra Oleum is an oil-to-milk cleanser: a four-oil complex (grape seed, MCT, apricot kernel, squalane) dissolves makeup, sunscreen and sebum on contact, and a mild, sulfate-free emulsifier turns it to a milk when water hits so it all rinses away without taking the barrier with it. Less post-wash dryness, no residue.

Key ingredients

Grape seed oil · Caprylic/capric triglyceride (MCT) · Apricot kernel oil · Squalane · Sodium lauroyl lactylate (mild, sulfate-free cleanser) · Tocopherol (vitamin E)

Full ingredients

Vitis Vinifera (Grape) Seed Oil, Caprylic/Capric Triglyceride, Prunus Armeniaca (Apricot) Kernel Oil, Sodium Lauroyl Lactylate, Isoamyl Laurate, Pentylene Glycol, Polyglyceryl-3 Oleate, Squalane, Fragrance, Tocopherol.

How to use

Face: massage onto dry skin to dissolve makeup and sunscreen, then wet your hands — it turns to a milk — and rinse. Body: apply to wet skin with your hands or a washcloth, massage, rinse with warm water. Follow with your step 4 oil or balm while skin is still damp.

NOW

FEEL IT

Glides on as an oil, turns milky as you add water, rinses with none of the tight, squeaky feeling. Makeup and sunscreen come off in one pass.

NEXT

BARRIER INTACT

Washing with oils instead of sulfates leaves your skin's own lipids where they belong, so post-shower dryness has less to work with.

OVER TIME

SKIN'S FIRST JOB

The barrier is the foundation every other step builds on. Keeping it intact every day is how the rest of the routine gets to do its work.

WHAT'S IN IT. WHAT THE RESEARCH FOUND.

KEY ACTIVES.
DOSED RIGHT.

Four oils on one sulfate-free base. Here is what published research says about the three doing the most work — studies on the ingredients, not on this bottle.

01 / 03
SQUALANE
≈13%
Squalene makes up roughly 13% of your skin's own surface lipids. Squalane is its stable form — a lipid your skin already recognises, so it conditions while you cleanse instead of stripping.
In cultured human skin cells, squalane at 0.005–0.015% restored a UV-suppressed collagen-recycling enzyme from 54% back to 94–98% of normal. Lab study, not a hydration trial.
02 / 03
GRAPE SEED OIL
12 WEEKS
66–75% linoleic acid plus vitamin E. The lightweight lipid that reinforces the barrier and comforts skin without heaviness.
Split-face, placebo-controlled study, 15 volunteers, 12 weeks: skin moisture and elasticity significantly increased on the grape seed oil side versus placebo (p<0.05). Leave-on gel, small study.
03 / 03
MCT OIL
2 HOURS
Caprylic/capric triglyceride from coconut. The silky, non-greasy oil that gives Tetra its slip and leaves a light conditioning film behind.
In 18 volunteers, a 15% caprylic/capric triglyceride emulsion significantly lowered water loss (p=0.005) and raised skin hydration (p<0.001) within 2 hours, and skin held almost twice the natural moisturising factor. Leave-on emulsion.

Study results describe research on the individual ingredient, not clinical testing of this finished formula. Individual results vary.

HOW TO USE

OIL ON. MILK OFF.

Face: massage onto dry skin to dissolve makeup and sunscreen, then wet your hands — it turns to a milk — and rinse. Body: apply to wet skin with your hands or a washcloth, massage, rinse with warm water. Follow with your step 4 oil or balm while skin is still damp.

It's oil-based, so the shower floor gets slippery. Mind your step.
