I want a treatment for my penis because it is a very small in size. I want to increase in length and width. (photo)

I have written a few papers about penis enlargement and evidence-based outcomes.
Penis enlargement surgery can offer modest improvements in both length and girth, but there are risks and limitations that should be carefully considered.
Lengthening Surgery: The most common method involves cutting the suspensory ligament that attaches the penis to the pubic bone, which can result in an increase of about 1 inch in flaccid length. However, this may not significantly affect erect length. Additionally, some men experience a "drooping" effect where the penis no longer rises in erection, but instead points downward.
Girth Enhancement: This can be achieved through fat grafting (using the patient’s own fat) or the insertion of dermal fillers or collagen-based materials. These techniques can add circumference, though fat grafts may have issues with uneven absorption, and synthetic fillers can lead to complications like infection, ulceration, or extrusion. The use of Alloderm (a type of cadaveric tissue) has been controversial due to risks of tissue reabsorption or complications.
Minimally Invasive Alternatives: Non-surgical treatments, like platelet-rich plasma (PRP) injections or fillers, are also options for improving penis girth and overall appearance. These methods generally have shorter recovery times and lower complication risks compared to surgery.
While surgery can lead to some visible improvements, the results may not meet all expectations, and the risks of complications are significant. For those seeking a modest increase in size, non-surgical options may offer safer alternatives. Consulting with an experienced surgeon is essential to determine the best course of action.

BellaFill is a semi-permanent filler that increases the girth of the penis. It lasts 5 years or more. I tell patients the only gain in length happens when the penis is flaccid. this is primarily due to gravty and the weight of the filler itself.

Both can be done with minimal surgery under local anesthesia as an outpatient in my clinic.
There are many ways to do it. You have to be seen and examined to determine what is best for you. Also important is your expectation and whether it can be met.
You have to be seen by a plastic surgeon or an urologist who specialize in male enhancement.
