Good nutrition will help your skin health, but as we age everyone's skin tends to sag.
The only other thing you can do is fill in the space with tricep muscle. Hypertrophy usually means high resistance. You can do it with body weight by making the lever longer, using gravity, etc.
Push-ups work the triceps most when you keep your hands right under your shoulders and your elbows tickling your ribs. Increase the resistance by doing them in decline position (put your feet up on a step, e.g.). For dips, first make sure your back is straight so you're working your triceps and not your legs - then you can lengthen your lever by fully extending your legs. Then if you need more resistance, you can put something heavy in your lap.
Do all of them slow and emphasize the eccentric (lengthening) phase.
@TSPoet, the only "suicide" drills I know are sprints with side squats ... what's the exercise that works the triceps??
