Sacral dimple, hip dips, roundness, crease definition - What procedures would you recommend? Any noninvasive options?

Based on these photos it appears that best option would be liposuction of torso with fat grafting of buttock/hips. In person or teleconference consultation with a board certified plastic surgeon with good reputation in BBL is recommended. Good luck.

Allow me to answer your question as best i can based upon your photos. However, please keep in mind that an in-person, or at least a virtual, consultation with physical exam is first necessary before any legitimate evaluation or final surgical recommendations can be made.

Let me first start off by saying, anything “noninvasive“ will be a complete and total waste of money, period!

There are currently only two FDA approved surgical options for augmenting/enhancing the buttock/hip area: 1) Buttock and cosmetic Hip Implants (which are soft semi-solid silicone rubber implants that cannot rupture &/or leak) and 2) Brazilian Butt Lift (aka BBL) - which utilizes the patients own fat from liposuction then transfers this fat into the buttock. On the other hand, BBL using fillers such as hyaluronic acids, Sculptra, etc… is a dangerous, guaranteed waste of money, and is NOT FDA approved. So what it comes down to, like any surgery, is proper patient selection and long-term results. Implants provide the only guarantee for a sustained permanent result and tend to be ideal for perking up not only lean or deflated buttocks but also providing substantial projection to any butt, which is what every single patient wants. Typically a combination of sculpting the waistline with liposuction and augmenting the buttock with implants +/- the hips with implants provides the best chance for a long lasting and desirable "hour-glass" figure. Based upon your photos, a Stanton Anatomic®️ shape buttock implant may serve you best.

Unfortunately, fat typically melts away leaving disappointing results after 12 months, often sooner. Unless your BBL surgeon is injecting only 200 to 300 ccs of fat into each buttock cheek, a large percentage of that fat is going to die. Dead fat leads to dents and dimpling like cellulite, unevenness, loss of projection, and fatty necrotic oil cysts which are hard marbles and can be very tender
Unfortunately, because ~80+ % of the fat transferred will melt away within a year or two, most patients, like yourself, are not good candidates for BBL because they lack an adequate amount of fat to harvest. Beware, if a surgeon asks you to purposely gain weight (i.e. fat) before BBL, know that the fat you lose first as you get back to your baseline weight after surgery is that very same fat that was transferred into your buttock, hence your new buttock shrinks first, the fastest, and the most...so please do not fall victim to this recommendation. Even those patients that had adequate amounts of fat pre-operatively, still end up seeking buttock implants after a year or so because most of the fat transferred melted away leaving them with minimal result. Fillers such as Sculptra are cost prohibitive, provided enough volume is injected (i.e. at least 400 cc of active ingredient costing over $300,000) and last only 12 - 18 months. Additionally, any physician promoting “biostimulators” for buttock enhancement is just a joke, and any board certified plastic surgeon promoting such, should not be trusted with your butt. So, if you're looking for a reliable, predictable, and long-term permanent option that also provides projection in the central buttock and hips, buttock and hip implants are your solution. Please note that an extremely few number of board certified plastic surgeons specialize in buttock or hip implants, so you may need to travel far and away from home to find this particular surgeon. Getting it done right the first time around is not only the best chance for success, but also will save you from a lot of headaches and money in the future. Glad to help.

It’s a little bit difficult to make a quality assessments for the pictures you’ve included.
Based on what you’ve included, your body is fine and you should probably consider not having surgical intervention.
If you want more projection of your hips, then adding a fat with the BBL could help.
I recommend strongly against creating a gluteal crease if you don’t have one. Doing so tends to lead to a disfigured look.
Personally, I think bottoms without the crease look better.
If you’re not born with a crease, then you shouldn’t try to create one.
Liposuction of that area only leads to problems.
Avoid surgery unless you really need it.
Your sacral dimple is also most likely best left alone.
I think you’re being overly self-conscious.
This is not to say that surgical intervention couldn’t make you look better.
There is however, enough risk and issues that go along with these procedures let choosing to have cosmetic surgery needs to be done carefully.
This includes meticulous work in regards to provider selection.
Personally, I think you look great and should probably stay away from plastic surgeons.
Best,
