The idea is that your skin tries to maintain an equilibrium. If you put oil on it, then more receptors for whatever oil it is will be activated, and the genes that produce oil will be turned off. I can say that the jojoba oil certainly made my skin less oily. But, if your body is producing more oil than it should for a separate reason, your oil production set point might be shifted enough so that applying oil wouldn't help.

It might be worth mentioning that sebum is made of a bunch of different molecules. Receptors are usually specific for just one molecule. So if you apply an oil that is similar to one of the many compounds in sebum, it could still very easily have an effect on gene regulation.

My skin is super oily as well and nothing other than Accutane helps. Jojoba oil doesn't do a thing for me in regard to oil production. I know some people feel it does help, but for me it doesn't. My skin is consistently oily no matter what.

I think for people with dry skin, jojoba oil can be wonderful and make a huge difference though.

Wow not many posters here on the oily skin forum anymore.

Anyway, the only thing that affects oil production is androgens binding to the sebaceous glands. Unless putting oil on your face somehow interferes with this process, I don't see how it could actually reduce oil production. My guess is that people who say it does are experiencing the placebo effect or it just makes their skin look less oily. I would also assume that the people who say it works didn't have very oily skin in the first place. Like how people say proactive works for acne, but they only had 3 pimples to start with.

The idea that the skin produces excess oil because it is dry has always been broscience as far as I know.

From what I have tried, accutane works amazing for oily skin, and vitamin A works a little bit, but you have to overdose for it to work. It's safer to just take a low dose of accutane. Spiro is also supposed to work really well, but guys shouldn't take it.

^ this.

Oils that contain high amounts of linoleic acid are supposed to actually inhibit androgen binding as described above. When applied topically. So this would slow oil production. At least according to another poster's research on this forum. Oils with high linoleic acid content are safflower, grape seed, and hemp.

According to this site, jojoba is only 1% linoelic acid.

Jojoba gives me clogged pores that I don't normally get from anything else...so yeah it didn't work for me either.
