26 overweight, will marionette lines caused by chubby cheeks go away if I lose weight? (Photos)

Hello, hope you are well. It's never a bad idea to allow your weight to stabilize prior to considering treatment options. You are young and can be expected to have good skin elasticity. So, when you lose weight, and the facial fat pads shrink in size, the skin should conform back to that shape. In other words, if you didn't see the problem just a few years ago at a healthy weight, you probably won't see it if you return to that weight again today. Fillers don't make a lot of sense in this context--you would be adding even more material and volume to a face you have already decided appears 'chubby'. Instead, if your skin continues to appear lax after weight loss, consider a minimally invasive skin tightening procedure like Morpheus8 (radiofrequency microneedling).
Best,Dr. Tower

Thank you for your question and photos. Achieving a desirable weight is likely to reduce facial lines caused by excess volume. You may also consider RF microneedling treatments to boost your body’s collagen production, restore your skin’s elasticity, and minimize the appearance of fine lines. I recommend scheduling an in-person consultation with an experienced, board-certified facial plastic surgeon. They will be able to discuss your concerns with you, answer any questions you have, and help you decide on the best course of action.

I recommend fillers to soften the nasolabial folds themselves and also lift around the mouth and cheeks to build underlying anatomical support. In our practice we combine Sculptra with other fillers "layered" on top and lasers, skin tightening treatments such as Thermage, Fractora, and Renuvion (J Plasma), thread lifting, and peels to get the most conservative, natural look. I suggest seeing a facial sculpting expert for a formal consultation. Best, Dr. Emer
