How to Treat Keloid or Hypertrophic Scarring in Incision Scars

Typically scars improve with time, and take about a year to get to their final situation.  They typically look their "angriest" between 1 and 4 months.

Scar massage helps.  Silicone scar products help.  Sometimes a little Kenalog injection is useful.  Sometimes IPL is helpful if the scar is very red in color.

Speak with your surgeon about your concerns.  

Good day! Three months is too soon for scars to be flat because your surgical incision sites will go through a maturation
process. For the first few months they will be red and possibly raised and/or
firm. As the scar matures, after 6-12 months, it becomes soft, pale, flat, and
much less noticeable. Some people are prone to keloids, which is an abnormal scar that becomes prominent. If you or a blood relative has a tendency to
keloid formation, please inform the doctor. Do not hesitate to contact your doctor regarding your concern and other aftercare solutions for your scar. Best of luck! #RealSelf100

Unfortunately, scarring is a
part of any surgical procedure.Whenever
possible, plastic surgeons place scars where they are well hidden by anatomic
structures.When breast augmentation is
performed, every effort is made to hide the incision.For this reason, they’re often placed in the
armpit, at the border of the areola with surrounding structures, or in the
inframammary fold region.It’s normal for scars to be red, raised, hard, and bumpy
three months following surgery. Over the
course of time, this should improve significantly. Scars generally take about 12 to 18 months to
reach maximum improvement. In six
months, the redness should be significantly improved.In the meantime, this keloid can be treated with massage
and the use of topical agents.In some
cases, silastic sheeting can be used and rarely, steroid injections may be
helpful as well.If scarring fails to
improve with these steps, a scar revision or skin resurfacing procedure may be
necessary.It’s important to maintain good communication with your
plastic surgeon.It’s still very early
in the post-operative period and significant improvement will probably
occur.Be patient,you may ultimately be very happy with your
result.

You may want to consider the injection of steroids into the incisions to help with healing.  Pressure and massage are also very good.

I treat my scars with silicone and steroids but a half mm scar is likely a knot.  Keep massaging it as you have been and it will likely go away.
