Pictures of over 60 explants without lift pictures. Is that because they look bad?

If you would like to have your implants out, you can do so at any time.  Your look after healing will be based on the amount of natural tissue you have, the elasticity of your skin, the size of the implants, and the length of time they were in place.  Your surgeon should be able to give you an idea of what to expect and if a lift is recommended.

Following explant, there is bound to be some degree of deflation and skin laxity. Some of the skin will recoil, but, depending upon the volume lost, some of the skin will not snap back and remain lax. Often times, these patients will need a lift/mastopexy, if they chose not to replace the volume lost.
With regards to your specific question, I would expect some skin laxity post explantation, at least initially. Some will recoil with time and, sadly, some will not. Age does play a role as well. Ultimately, this often a function of the degree to which the skin was initially stretched with augmentation. This may take several months to settle.The procedures are commonly performed simultaneously, however, they may be staged. Post explant lifts are fairly common and have similar outcomes to other lifts.
With regards to your specific question, the lack of available post explant lift photos may, as you said, be a function of age. Older patients (who often undergo explant) tend to shy away from making their before and after photos available on the internet (likely a generational phenomenon). I would encourage you to seek out consultation as many of these result photos are available in the setting of consultation. 
As always, discuss your concerns with a board certified plastic surgeon (ABPS).

Good day!
Generally speaking, our skin will stretch overtime and it will largely
depend upon the patient's age, weight, and other factors prior
to explantation, such as implant size, pregnancy or breastfeeding. However, it is hard to assess without an in-person examination or at least photos. It is best to consult your plastic surgeon
regarding this concern and discuss detailed information and realistic
expectations. Best of luck! #RealSelf100

There are several factors that determine the result of a breast implant removal. Your skin could stretch back under several conditions: (1) if your breast tissue did not decrease over the period from your original breasts; (2) if your pectorals major muscle maintained its bulk; (3) if your pectorals major was not cut during insertion; (4) or if it was cut during insertion, it was repaired successfully after explantation; (5) if your rib contour was not altered by the implants. In other words, your skin has to be supported by adequate volume in the breast. In general, breasts with sub pectoral implants tend to do better than sub glandular implants after explantation, because the breast tissue is less stretched by the implants. Breasts that had no contracture tend to do better.Your question is a good one but complicated to answer without more information. I hope this helps.

It is not so much your age but the shape of your breasts and amount of breast tissue you have that dictates the result. The link below includes a number of patients with removal in patients over 50 without lift.
