The structures you are referring to in the image are normal oil (sebaceous) glands of the skin. They can be more visible at areas of thin skin such as eyelid or lip regions. Tretinoin is not likely to help as there is no blockage of their pores. If troublesome, light cautery may be helpful.
Hope this is useful to you.

I would recommend volume correction using fillers - they can address your concerns and provide rapid improvement.
An expert injector can provide filler enhancment by:
1) strategic placement to areas of tissue shrinkage contributing to your areas of concern and
2)technical and safety optimization (eg. knowledge of relevant anatomy, use of cannulas and prior evaluation of regional blood vessels using skin ultrasound)
Seek a board certified plastic surgeon or dermatologist with experience to optimize your outcomes.
Hope this helps!

The clench muscles of the face (masseters have their greatest bulk at the side of the cheeks just above the jawline. If you clench, you will feel this muscle tighten and you can follow it's course from the angle of the jaw up towards your cheekbone.

Botox injections for TMJ pain should be done at the third of that muscle which is lower on the cheek and toward the angle of the jaw. That location is well away from the smile muscles of the face - zygomaticus and risorius. If injected toward the upper third, there is a risk of affecting zygomaticus. I suspect that may have been the case in your situation.

Given the amounts injected, full recovery of your smile is expected at 3-4 mths.

I typically don't need to inject temporalis to achieve TMJ pain relief.

Dermatologists learn about the management of hyperhidrosis during their training. Currently, there are multiple options available including lotions/gels, injectables and oral medications. You may want to consider calling the office of local dermatologists in your area to determine who can help in a convenient location to you.

Botox in the upper face  is a reliable was to weaken over used facial expression muscles to provide a more youthful and relaxed (ie less stressed and tired) appearance. While Botox costs can vary (average CDN$10/unit) - an essential element is the expertise/experience of the injector. For individual patients, the size and strength of muscles to be treated must be considered to provide the desired effect. In the frown line area for example, the frown muscles can be much larger and stronger in men than women - requiring larger doses (25-35 units). The size of foreheads also vary between individuals - so this needs to be considered along with strength of underlying muscles (typically 10-20 units). Over-treatment of this area can lead brow droop or heaviness in those who have lower brows to begin with. Often, I recommend a Botox lid elevation treatment to avoid this issue (20 units). Crows feet lines can improve with standard treatments of 20 units and we often add 10 units below the lower lid to provide  more curvature to the lid lower margin.
