Whilst the scar is still recent, start by using the Calendula Remedy (or Calendula Concentrate or both, always the concentrate before the balm). Always make sure to massage into the scar and its surrounding area at least 4-5 times a day - the important thing is to keep the area moisturized and supple and not to let it dry out. The earlier you can start doing this, the better!
Once the scar is completely healed, the best product to continue with is the Mother's Intensive Oil which is excellent in helping with skin renewal in the area and to lessen the effects of the stitches. Again, the best way to use this is to massage into the area regularly (at least 3-4 times a day).
