Botox for Poor Skin Texture from Pores, Oil, and Scars?

A small study by A Shah published in the Journal of Drugs and Dermatolgy in 2008 entitled "Use of intradermal botulinum toxin to reduce sebum production and facial pore size" suggests that Botox may help wth pore size and sebum production. The study was small so larger studies are needed to see if other doctors get similar results.
Botox should have no effect on scarred tissue. Subcision may help for scarred tissue.
Retin A or Accutane (not if you are pregnant) may be better for reducing sebum producition, and less costly.
I would encourage a skin care conslt with a good dermatologist or plastic surgeon.
You should be able to bring up these findings in your consult.
Good luck!

Botox is not FDA approved for use in treatment of skin pores and acne scarring. I would recommend seeing a board certified dermatologist who will have a variety of treatments to offer, both pharmaceutical and lasers.

There is no physiologic reason why this should work, and probably doesn't! Accutane--low dose, intermittant, and long term can help reduce sebum (oil). The SmoothBeam laser definitely reduces sebaceous gland activity, hence reduced oil and acne. Fraxel Laser resurfacing can improve scars, and may help shrink pore size due to adjacent collagen remodelling.

There isn't a well-established method or standard for Botox to help in skin texture, pore size, oil, or scarring. There have been some reports by dermatologist & plastic surgeons that Botox cosmetic has helped not only facial wrinkles, but also skin quality. Keep in mind, Botox cosmetic is not FDA approved for intradermal treatment. Any positive results would be delayed, and there may yet be unknown risks to this method.
Speak with a cosmetic physician who provides Botox, and determine if Botox cosmetic is appropriate for you.
