What can I do about the bags / wrinkles under my eyes when I smile? (photos)

Thank you for your question and photos you provided. You are a beautiful woman and do not need any treatment to your face at this time! Enjoy your youth and re-consider facial treatments in 5 -10 years.

For puffiness and sagging under the eyes, we often use Renuvion helium plasma radiofrequency energy to achieve incredible results and take years off of your appearance. Combining RF energy and cool helium plasma, the signs of aging (wrinkles, pigmentation, skin laxity) are improved in a ‘Nonsurgical Eyelid Lift.' The focused heating tightens and peels the upper layers of skin with extreme precision, leaving the surrounding area undamaged, smoothing and tightening the periorbital skin, and improving the overall skin quality around the eyes. It's an aggressive treatment, and the recovery time is longer than with other nonsurgical procedures, but the results can be life-changing.​ See an expert to determine if this is the best solution for you. Best, Dr. Emer

Thank you for your pictures and questions. In general this part of the anatomy appears overall normal. However, there might be some treatments you could attempt to soften the appearance. Neuromodulators (Botox) can help soften the muscle activity in this area and also laser treatments might also help.
Good luck!
