Argan Oil

What it is

Argan oil is obtained from the kernels of the argan tree, Argania Spinosa. Its standard cosmetic ingredient name is Argania Spinosa Kernel Oil. It is used in facial oils, creams, balms and hair products, where it contributes a plant-oil texture. The oil’s color, scent and feel depend on how it is processed and on the other ingredients in the formula. A label listing argan oil does not reveal its percentage, and products that contain it can feel very different from one another.

What it does

• Softens dry-feeling skin. Argan oil is an emollient that helps make the surface feel smoother and more flexible.
• Adds richness and slip. It can make a moisturizer spread more easily and leave a conditioned finish.
• Helps reduce moisture loss. Like other oils, it can provide some occlusion when left on skin, especially as part of a cream or face oil.

Who it suits

Argan oil may suit you if you enjoy facial oils or want a richer layer over a moisturizer. It can also be a useful part of a body or hair product, though those formulas are made for different uses. If you have oily or combination skin, the finished formula and how much you apply matter more than the ingredient name alone. Some people prefer a light lotion and others like the cushion of an oil; neither choice is more virtuous. Plant oils can be unsuitable for some individuals, so review the full ingredient list and patch-test a new leave-on product if you are concerned. If irritation persists or you have a skin condition, get advice from a dermatologist instead of relying on an oil.

What to pair it with, and what not to

You can use argan oil after water-based products or over a moisturizer containing glycerin or ceramides. It can also fit into a routine with retinol or exfoliating acids; just add one new item at a time, and do not use the oil as insurance against a strong active. Follow each product’s directions, and consider using the oil only where you want extra emollience. If it leaves a finish you dislike, switch to a lighter moisturizer. Apply sunscreen in the daytime as directed.

Skin Realist check: A face oil is a texture choice, not a membership card for people with good skincare habits. Pick the finish you will actually enjoy using.
