What a face oil can and cannot do.
Argan, and the thing about oils that almost nobody says out loud: they do not hydrate skin, and using them as though they do is why yours still feels tight.
Let me start with the correction that changes results fastest, because I have had this conversation several hundred times. An oil does not hydrate your skin. Hydration means water. Oils contain no water. What an oil does is seal, softening the surface and slowing the rate at which the water already in your skin evaporates away. That is genuinely valuable, and it is a different job from the one most people think they are buying.
It matters because perimenopause takes both things at once. Falling estrogen means less oil production and less water-holding capacity, so skin is short of lipids and short of water together. Put oil onto dry skin and you seal in the dryness. Put it onto damp skin, or over a water-phase serum carrying humectants like glycerin or hyaluronic acid, and you have given the skin water and then closed the lid on it. Same bottle, same few drops, completely different outcome. This is the single most common mistake I see.
“Oil on dry skin seals in the dryness. The oil was never the problem; the order was.”
As for argan specifically. It is roughly 80% unsaturated fatty acids, dominated by oleic acid at around 45% and linoleic at around 35%, and it is unusually rich in tocopherols, the vitamin E family. That linoleic content is the part worth caring about: linoleic acid is a building block of ceramides, so a linoleic-rich oil is not only sitting on the surface, it is contributing raw material to the barrier. The tocopherols are an antioxidant load and also what keeps the oil itself from going rancid quickly.
Two things worth knowing when you buy it. Real cold-pressed argan smells faintly nutty and looks pale gold; a completely odourless argan has usually been deodorised or refined, which costs some of the tocopherols along with the smell. And oils do expire. Store it away from light and heat, and if it ever smells like old crayons or putty, it has oxidised and belongs in the bin, because a rancid oil is a pro-oxidant applied to your face.
Two claims I want to take apart. First, no oil tightens skin. You will see argan, rosehip and half a dozen others sold for skin tightening, and the effect people report is a temporary surface film, gone by the next wash. Skin laxity is collagen and elastin and fat pads, none of which an oil reaches. Second, comedogenic ratings. Those numbers you see, the zero-to-five scale, came from a 1970s assay on rabbit ears, applied at concentrations no product uses. They are not a reliable guide to what an oil does on a human face, and treating them as gospel rules out perfectly good oils. Your own skin over two weeks is better evidence than a table.
How I use it, and how I ask clients to. A few drops as the genuine last step at night, over serums, on skin that is still slightly damp. Warm it between your palms first so it spreads rather than drags. Nights when skin feels tight, not necessarily every night. And if you are using bakuchiol, argan sits happily over it; the two were made for the same job.
The honest summary: a good oil is a finishing step that makes skin more comfortable and slows water loss, and it is not a treatment. If your skin is dry in this decade, the oil is the last quarter of the answer. The barrier step underneath it is the other three quarters.
