I discussed in my book “The Fine Art of Looking Younger” that the essence of facial aging is a combination of volume loss and sagging. As a specialist having offices in Manhattan and Long Island, this type of question comes up a lot. A lot of people who underwent illness unfortunately lose a lot of fat in their face more than any other part in their body. That is why a lot of my patients are fit people who chose liposculpture to help them get rid of problem areas in their bodies. In addition, physical and emotional stress accelerates aging. However, I would advise against gaining weight to fill your face. In a country where there is a high rate of obesity, being overweight is never to someone’s advantage. Adding weight to your face is also sacrificing the appearance of your body and there are also medical consequences. Before you pursue surgical procedures, it is very important to restore some of the foundation of your physical by having a healthy lifestyle. You can choose to get fillers, but before doing that, find the right group of professionals such as a fitness instructor and go to the gym, exercise and have a healthy diet. I also advocate supplements such as omega 3, fatty acids and antioxidants. In terms of lifestyle, I also do in my own personal life the same things I tell my patients that if you live a healthier lifestyle then the quality of your skin and facial appearance will improve. In terms of addressing the areas the you feel will benefit by you gaining weight, there are fillers such as Radiesse, Sculptra, hyaluronic acid like Restylane, and Botox to lax some of the muscles. If you’re not quite ready for a facelift and you just want to fill out the areas then by all means consider the less invasive option. Consider doing that in conjunction with adopting a healthy lifestyle and doing things that are good for your heart and lungs. In addition, most of our patients feel real wonderful from just straightforward skincare. In our practice, we have a medical spa and we’ll do something called Hydrafacial. Hydrafacial is using water technology to work like the crystals do in microdermabrasion. This helps make the skin glow and this ultimately helps patients feel wonderful about their appearance. I’m not negating any benefit of a lifting procedure but if you want to push off that lifting procedure for a while you can try all these things. If you feel that you want to improve your jawline and neck skin, then a lift will be appropriate. I hope that was helpful, I wish you the best of luck, and thank you for your question.
