Trying to choose a non surgical skin tightening procedure for face and neck. Does skin thickness really matter?

Before jumping into more expensive, light and other energy-based gizmo treatments, you should be aware that the hard science to back up the use of these often "here-today-gone-tomorrow," bells and whistles devices lags woefully behind the heavy marketing hype and social media buzz to promote their use. So, before pursuing this route any further, a heavy dose of "buyer beware" might be in order.
On the other hand, robust HA fillers have been successfully used for nonsurgical cheek augmentations, nonsurgical temple augmentation and browlifting, as well as for defining and straightening the jawline, diminishing jowls and for achieving a nonsurgical filler necklift. The aforementioned are all advanced injection techniques, so not to be left to the hands of novice, inexperienced injectors familiar mostly with filling simple smile lines with ordinary Juvederm or plain Restylane.
Before wasting any more time and money, you would be wise to make sure to consult an experienced, board certified cosmetic dermatologist. In the hands of experienced injector, if you wished, ALL of the aforementioned could be done in one approximately 45 minute treatment session. What's more, the results are typically immediate and the treatment usually engenders little to no significant downtime.
Hope this helps and best of luck.

When considering non-surgical skin tightening procedures for the face and neck, skin thickness can indeed play a role in determining the most appropriate treatment, but it's not the only factor to consider. Here's a breakdown of the different options and considerations:

Skin Thickness:

Skin thickness can influence how well certain treatments work. Thicker skin may respond better to deeper treatments, while thinner skin might benefit from more surface-level approaches. However, a skilled provider can often adjust treatment settings to accommodate different skin types.
Morpheus8:

This treatment combines microneedling with radiofrequency energy to stimulate collagen production. It typically requires multiple sessions to see significant results. If you haven't noticed changes yet, it may be worth continuing with additional sessions as results can be cumulative.
Ultherapy:

Uses ultrasound technology to target deeper layers of the skin, promoting collagen production. It's often recommended for lifting and tightening, particularly in areas like the brow and jowls. It can be effective for individuals with mild to moderate skin laxity.
Sofwave:

This is another ultrasound-based treatment, similar to Ultherapy, but it targets the mid-dermis. It is designed to improve skin laxity and fine lines and may be a good option if you're looking for a less intense treatment than Ultherapy.
Consultation and Assessment:

It's important to consult with a qualified dermatologist or cosmetic surgeon who can assess your skin's unique characteristics, including thickness, elasticity, and overall condition. They can help you determine the most suitable procedure based on your specific needs and goals.
Combination Treatments:

Sometimes, a combination of treatments can yield the best results. Discuss with your provider the possibility of combining different modalities to address various concerns like jowling and brow drooping.
Ultimately, the choice of treatment should be based on a comprehensive evaluation by a professional who can tailor the approach to your skin type and desired outcomes.
