The Complete Argan Oil Guide: From Argan Tree to Your Skin

In the semi-arid landscape of Morocco's Souss valley, a thorny, gnarled tree produces one of the most nutritionally dense oils in the natural world. The argan tree — Argania spinosa — has been growing here for 25 million years, long before modern cosmetics, long before the concept of skincare as an industry.

Berber women have cold-pressed its kernels for centuries. They used it to cook, to heal, and to protect skin and hair against the harsh desert climate. Today, that same oil is sold in luxury boutiques worldwide. But not all argan oil is the same — not even close.

This guide will tell you everything: the biology of the tree, the difference between cosmetic and culinary grades, how to spot genuine cold-pressed oil, and exactly how to use it in your daily routine.

1. Where argan oil comes from

The argan tree grows exclusively in a UNESCO biosphere reserve covering roughly 2.5 million hectares in southwestern Morocco. It's adapted to arid conditions that would kill most trees — it can survive droughts lasting years, and its roots extend deep enough to prevent soil erosion across entire hillsides.

Each tree produces between 30 and 100 kilograms of fruit per year. The fruit resembles a small olive — a fleshy outer pulp surrounding a hard nut, inside which sit two or three almond-shaped kernels. Those kernels are the source of argan oil.

2. How it's made: cold-press vs solvent extraction

Traditional argan oil production is almost entirely done by women's cooperatives using stone mills. Once the outer pulp is removed and the hard nuts cracked open (by hand, on flat stones), the raw kernels are ground into a paste and water is added. The oil is then extracted by kneading the paste — a process that can take several hours per batch.

Cold-pressing maintains temperatures below 50°C throughout, which preserves the full nutritional profile: vitamin E (tocopherols), squalene, plant sterols, and the delicate phenolic compounds that contribute to argan's anti-inflammatory properties.

Solvent extraction — used in industrial production — uses hexane or other chemical solvents to strip oil from the kernels at scale. The resulting oil must be refined, bleached, and deodorised, destroying most of its active compounds in the process. The end product has a longer shelf life and lower cost, but it's a nutritionally inferior oil.

Our argan oil is always cold-pressed, always from certified cooperatives, and always tested for purity before bottling.

5. Argan oil for your face

Apply 2–3 drops to clean, slightly damp skin. Press gently into the face — do not rub. Use as the final step of your morning routine, after serum and before SPF. At night, it works beautifully as a facial oil or mixed with a moisturiser for extra nourishment. It's non-comedogenic for most skin types, though if you have very oily or congested skin, use it only at night initially.

6. Argan oil for your hair

Pre-shampoo treatment: apply generously from mid-lengths to ends, leave for 30 minutes (or overnight with a towel), then shampoo as normal. As a leave-in: warm 1–2 drops between palms and smooth over dry hair ends to control frizz and add shine. Avoid the roots to prevent greasiness.

7. Argan oil for nails & cuticles

Massage a single drop into each cuticle before bed. The high vitamin E content and linoleic acid significantly improve cuticle condition and brittleness within 2–3 weeks of consistent use. It also works as a nail-strengthening treatment when applied to the nail plate itself.
