I had a breast augmentation and I've been told these scars are a reaction from my body to the dissolvable sutures? (Photo)

You have what is referred to as a train track scar. Usually this is from skin growing down along holes in the skin where sutures are placed on the surface. It can happen from leaving permanent sutures too long or from dissolvable sutures that take longer than 7-10 days to dissolve. It's rare for the body to react to buried (under the skin) sutures in this exact pattern. Also, dissolvable sutures are usually clear or tan and are not usually black. Either way, you can use scar cream to improve the scar quality in general, and after 3 months, laser can be used to smooth them further. If you were to "redo" the scar (meaning cut it out to get rid of the dots), it would end up noticeable longer. 

Your scar is not due to a reaction to dissolving sutures but rather because of the external sutures used to close the wound. External sutures should be removed within 10 days to limit the risk of scarring.
I do not use external sutures for breast augmentation. I use an internally woven technique to eliminate the risk of this concern. I would talk to your plastic surgeon to discuss options to improve the scar which could include topical scar creams as well as revision.

Your suture marks are from the nylon sutures. You need to reexcise the scar with the dots next to it and close with deep absorbing sutures and sub cuticular sutures. No exterior nylon sutures. It will then heal without the marks next to the line. Thanks

This appears to be the result of permanent sutures in the skin, not dissolvable sutures beneath the skin. The only way to really improve it would be scar revision.

What you have are train track or railroad scars.  This occurs from leaving sutures in for too long.  Typically black sutures that are removed are not dissolvable.  It would be rare to have a "reaction" to the sutures.  

dissolving sutures, even if they were the sutures were left in place too long, that is why you have "track" marks on both sides of the incision. The marks will fade with time, but will be there forever

Based on your description and photo it appears as though external nylon sutures were used to close your incision. This are not dissolvable and tend to leave "railroad track" scars if left in too long.  

Hello, it's hard to speculate whether the sutures were a cause or contributor to your scars, since there are many potential causes such as genetics, surgical technique, postop complications, etc.  In my experience it is very uncommon for a person to have an adverse reaction to the suture material.

Without examining you and knowing exactly what sutures were used its difficult to be 100% certain with online advice. Based on the photos it looks like train-tracking from sutures that were left in too long, or from absorbable sutures that were used externally. If you are seeing black sutures though then it sounds a bit odd for absorbable as most absorbable are clear, yellow, white or (less commonly) purple. Black sutures are usually nylon, which is not absorbable. I personally only use clear, absorbable sutures all hidden within the skin so there is never a visible suture nor a visible suture mark but there are lots of surgeons who use nylon and get great results. I would strongly suggest you get a second opinion from board-certified plastic surgeon with expertise in breast surgery to see if there are any options to improve the scar. Hope that helps! 

Your hash marks on either side of your main scar are due to a non-absorbable suture being used for the closure of your skin.  If it was black in color it was a non-absorbable suture and may have been left in place a bit too long before it was removed. We always use all absorbable sutures that are placed entirely under the skin.  Therefore, no sutures ever need to be removed, and this "rail road track" appearing scar that you have been left with can't occur. You could certainly consider having these scars revised to rid your skin of the small scars on either side of the main scar. Best of luck to you!
