Hello Kalpna,

What an interesting question. I'm no expert and will be interested in the answers of other ResearchGate members, but I think that sebum production is more hormone regulated (dihydrotestosterone - DHT).

This website gives a simplistic view of  this:

Search for DHT.

. . . and this paper gives greater detail - again search for DHT:

Makrantonaki, E., Ganceviciene, R., & Zouboulis, C. C. (2011). An update on the role of the sebaceous gland in the pathogenesis of acne. Dermato-endocrinology, 3(1), 41-49.

See Jojoba on p.991 in this paper:

Aburjai, T., & Natsheh, F. M. (2003). Plants used in cosmetics. Phytotherapy research, 17(9), 987-1000.

https://www.researchgate.net/publication/9027603

This mentions its function as a humectant and its ability to form a protective film.

So I don't think this gives a biofeedback effect to reduce sebum production, but I might be wrong, and would be really interested to find out.

As Aburjai and Natsheh are ResearchGate members, perhaps you could ask them through RG?

Very best wishes,

Mary 

Article Plants Used in Cosmetics

Hi Mary 

Thank you so much for your informative reply. I will read the attachments with interest. Yes it will be very interesting to see if anyone had done any studies to demonstrate if skincare creams and emollients can give a bio-feedback mechanism to increase / reduce sebum.

Best wishes, Kalpna 

Jojoba oil can be good for dry skin used on its own as a natural skincare product or added to your normal cream. Jojoba oil’s moisturizing, healing and anti microbial benefits for skin make it a valuable natural oil for both oily and dry skin.

A jojoba oil benefit is that it plays the role of sebum and moisturizes our skin and hair when our body stops doing it naturally. On the other hand, too much sebum, which happens during puberty or when hormone levels are high, can result in oilyskin and acne.
