Sorry, but, since you added the gel stain, it will have to be all stripped to be able to get back to a decent finish.

Were the cabinets factory-finished? Do you have more photos showing the damage and a dime or finger for scale?

If the areas are tiny and the gel stain is quite opaque, you can have a semi-gloss paint (not stain) mixed at a paint store (take a door in for a computer match) to use with a tiny brush and a delicate touch. Test first on the back of a cabinet door from someplace unobtrusive like over the fridge. You may need to overcoat it with clear poly to even up the sheen. It's very important to test first to avoid making things worse. The current finish and the new paint have to be compatible to keep the paint from just flaking off. There are lots of how-to videos from pro furniture restorers on youtube.

Or do a very good cleaning, sanding, and prime it all with a good quality bonding sealing primer, and repaint from scratch.

Did you coat clear finished cabinets with gel stain?

Or touch up factory espresso finish with gel stain?

Where did the cabinets come from. IMO most espresso cabinets were from China since there they use many different woods when doing cabinets and hence the espresso stain to blend in all the different materials. No matter what the gel stain needs to be removed . IMO you strip and paint them A huge job made worse by now needing to strip the gel too but the only way. I however suggest getting this done professionally and no matter how many you tubes show you DIY unless you have stripped and sanded and sparyed and apinted many cabinets DIY does not stand up likre afactory finish and very often does not look great. I guess since they are bathroom cabinets you could try in the smallest one to try DIY but no way in a kitchen. To have them done right will not be cheap so check out the cost of replacement too .

If you do decide to sand them all down, and then repaint them, make sure you do proper prep work, and cleaning and sanding, and use a good quality sealing bonding primer, and use the correct paint for painting cabinets and follow the instructions on the can for drying times to recoat. Painting cabinets is a lot of work, but, it can be done.

Thanks for all the comments and tips. These are pre-finished cabinets from the builder. I hate them! Not the style, they are simple shakers but the fact the finish is wearing so poorly. Between the wear around the knobs and in the bathrooms from water I would have a large investment in refinishing them all as they are in all 5 bathrooms, butlers pantry, built ins and command center. I used Gel stain as a touch up not over the entire cabinets. Is anyone familiar w/the product in the photo attached. Someone recommended this to me but I am skeptical based on my other recommendation. Thanks for all the feedback!

That will not work on your cabinets. It does work well, on regular stained furniture, that is walnut oil based stain, etc. Your cabinets appear to be painted, and not stained. Since you put the gel stain on them, to get them decent, you will have to strip them, and redo.

Did you lightly sand before using the gel stain? And did you apply it to the whole face or just worn spots? I’ve used gel stain on old furniture and it turned out great. It supposedly doesn’t absorb into the wood. If you got streaks there might have been something wrong about your prep work.

I’ve also used Restor a finish... worked great on an old dresser, didn’t work at all on bathroom cabinets.

I’ve had your kitchen! You can do many things to bandaid - but the issue may not resolve to your satisfaction. I suggest you save time and frustration and replace the cabinets as soon as your budget allows. Until then, if these are uppers, just take them down and replace with shelves.
