Does Restylane Thicken Earlobe Skin So I Can Keep Stretching/Dauging my Ears?

Hi sfo.  It's unlikely that Restylane or any other filler will help you achieve your goal of continuing to stretch your earlobe further.  

Although dermal fillers can be used to augment tissue that has lost volume, the primary purpose is not to strengthen the tissue, which is what you are looking for.  We would suggest you stop stretching the earlobe vs. trying to use a filler to strengthen it.

Yes, fillers such as restylane and juvederm are excellent choices for augmenting earlobes.  They typically last 9 - 15 months and are easy to use.  While this will not actually increase the amount of skin, it will expand it and therefore give you a nice result.

The other option to look at is the size of the other earlobe - that is, it may in fact need to reduced.

Sure, Restylane is great for plumping up the earlobe.  The reason your earlobe split is that you are abusing the earlobe and stressing the blood supply to this tissue.  Eventually the earlobe at its most dependent part will give away as there is not enough blood circulating in this location to sustain the tissue where it is being stressed by your manipulation.  In fact filling this thin spot with Restylane may choke off the last little bit of circulation in this tissue and hasten its breakdown.  I predict that you will figure this out and ultimately realize that your earlobe cant support what you are trying to accomplish.
