I want to have a more slimmer snatched face, what could I do to help achieve that? One side of my face is bigger/uneven. (photo)

First, it's important to know that facial asymmetry is extremely common - almost everyone has some degree of it! Most people's faces aren't perfectly symmetrical, and often we're much more aware of our own asymmetries than others are.Since you've already had success with masseter Botox, that's a great foundation. Here are some treatments that can help achieve a slimmer, more contoured facial appearance:
1. Masseter Botox refinement:You can have more Botox injected on the side that protrudes more to create better balanceThis can be fine-tuned over multiple sessions to achieve optimal symmetry
2. Facial contouring with dermal fillers:Strategic filler placement can help balance asymmetries and create more defined contoursAreas like the chin, jawline, and cheeks can be enhanced to create a more "snatched" appearanceFillers can also be used to build up the smaller side of your face for better symmetry
3. Lower face liposuction with subdermal skin tightening:Liposuction can be done to sculpt/define the lower face. The subdermal tightening component helps with skin laxity and creates a more defined jawline- this is particularly effective for overall facial slimming
I'd recommend consulting with a board-certified plastic surgeon or dermatologist who specializes in facial contouring. They can assess your specific anatomy and create a treatment plan that addresses your asymmetry while achieving the sleeker facial profile you're looking for.

Achieving a slimmer, more balanced facial appearance can involve a combination of treatments, depending on the underlying causes of asymmetry and fullness. Since you've had success with masseter Botox, which reduces muscle size and can help contour the jawline, here are additional options to consider:

Dermal Fillers:

Purpose: Fillers can be used to enhance facial symmetry by adding volume to areas that appear smaller or less defined. They can also help contour the cheeks and jawline for a more balanced appearance.
Recovery: Minimal downtime, with possible swelling or bruising.
Duration: Results typically last 6-18 months, depending on the type of filler used.
Buccal Fat Removal:

Purpose: A surgical procedure to remove excess fat from the cheeks, which can help create a more defined, slimmer face.
Recovery: Swelling and bruising are common, with downtime of about 1-2 weeks.
Considerations: Best suited for individuals with fuller cheeks who desire a more contoured look.
Ultherapy or Radiofrequency Treatments:

Purpose: Non-invasive treatments that use ultrasound or radiofrequency energy to tighten and lift the skin by stimulating collagen production.
Recovery: Minimal to no downtime, though some redness or swelling may occur.
Results: Gradual improvement over several months, lasting up to a year or more.
Facial Contouring Surgery:

Purpose: Surgical options such as chin augmentation or cheek implants can address structural asymmetries for a more balanced facial appearance.
Recovery: Involves more significant downtime and recovery compared to non-surgical options.
Continued Masseter Botox:

Purpose: Regular treatments can maintain a slimmer jawline, especially if muscle size is a significant factor in facial fullness.
Frequency: Typically every 3-6 months, depending on individual response.
It's essential to consult with a board-certified dermatologist or plastic surgeon to discuss your concerns and goals. They can evaluate your facial structure, provide personalized recommendations, and develop a treatment plan tailored to your needs. Photos and an in-person examination will help them determine the best approach for achieving the desired results.

You will likely have the best results from a combination of treatments. Botox can help to slim the masseters, help with dynamic wrinkles, improve brow asymmetry, and create a lip flip. Fillers can also create balance with volume discrepancies and improve contours. Morpheus8 treatments combine RF technology with microneedling to improve overall skin tone and texture.

Every single individual on this planet has facial asymmetry where one side of the face is quite a bit fuller and rounder than the other. In the majority of people it’s the left side. If having had Botox in the masseter helped you, then continue with the procedure. On the other hand, you have to realize that a lot of fullness is related to your being still young as well as the hereditary factors. Keeping a healthy weight is the most important thing you can do for yourself and your face. A Plastic Surgeon who specializes in micro cannular liposuction can also reduce the size of your face if absolutely desire to do so.
