My boobs are saggy and have stretch marks, I'm 30 years old. How can I have better looking boobs? (Photo)

You may well be a candidate for a mastopexy (breast lift).  If you require a larger size, implants may also be an option.  You have an asymmetry between your breasts, so your case is more difficult than a straightforward breast lift.  Experience in your surgeon is a must!

Thank you for your photos. There are three surgical options for you to consider and the correct one for youdepends on your desired breast appearance. As you age the volume of the breast above the nipple decreases and the skin relaxes. The majority of breast volume remains below the nipple giving the characteristic appearance of sagging.A breast lift can place the nipple back to a higher position and remove the tissue that is extending below the fold. This will not alter the overall volume of the breast and will not restore fullness to the breast above the nipple. Volume can be added to the upper pole only with fat grafting or to the entire breast with a breast implant. Fat is more subtle and with one operation will not yield the same projection as an implant. Implants come in multiple profiles and the exact upper pole fullness can be reliably achieved with these devices.The combination of skin reduction and volume augmentation will improve the appearance of stretch marks which are present on the breast.Seek out a board certified plastic surgeon to evaluate you and discuss these options in more detail.Good luck and I hope this was helpful.
