Photos are not the ideal way to diagnose, but from what can be seen the appearance, size, shape and distribution of the bumps is very consistent with papular acne scars, which are typically seen on the chin and nose, but can be on the back and chest, as well. They are much like small hypertrophic scars. Intralesional anti-inflammatory injections, Scalpel Sculpting and light electrocautery all may be used to treat this condition, and I typically try a test area of each type of treatment to see which works best for a particular patient. Most often, in my experience, light electrocautery excels as the treatment of choice and numerous sites can be treated in one treatment session. Overall, there is typically a sixty to eighty percent overall improvement in appearance. No doubt in your quest for treatment you will be hawked all kinds of expensive, light and energy-based gizmos. But, you would be wise to keep in mind that the reality is that the hard science to support the use of these "bells and whistles" devices lags woefully behind the heavy marketing and social media buzz that surrounds them. You would therefore also be wise to consult with a board certified cosmetic dermatology expert. And, one final word to the wise; don't go into any consultation requesting any particular treatment that Dr TikTok or your favorite skinfluencer has been pushing because to your later disappointment, frustration, and financial loss, you were likely to get what you asked for. Hope this helps and best of luck.
