The photos were reviewed and show shallow lower/outer buttock depressions with some skin texture and a defined gluteal crease; photos alone cannot tell whether this is mainly natural anatomy, cellulite-type tethering, muscle tone, or a small volume deficit. Chronic glute clenching can contribute to tightness and posture patterns, but it usually does not permanently reshape the buttocks by itself. If you want to avoid a BBL and injections, the options are limited but not zero. Glute-focused strength training, hip mobility work, and physical therapy can help if you habitually clench, have pelvic floor tension, or have underactive glute muscles. These can improve tone and shape gradually, but they will not release a true tethered dimple or fill a hollow the way fat grafting or filler would. For dents caused by fibrous bands or cellulite, treatments such as subcision, radiofrequency, or cellulite devices may soften the contour, but the improvement is usually modest and sometimes works best when combined with filler or fat. Liposuction alone is usually not the answer for this type of indentation and can make depressions look worse if volume is removed around them. I would see a board-certified plastic surgeon or dermatologist who treats cellulite and gluteal contouring so they can examine the area standing, flexing, and relaxed, then tell you whether this is a muscle/tension issue, cellulite tethering, or a volume issue.
