A very concentrated formula that encourages the healing of open wounds and grazed skin (calendula is a rapid tissue granulator and heals skin very quickly). Avoid application to infected or dirty wounds because it encourages fast healing which can 'lock' things in. If using this concentrate to treat acne scaring ensure it is applied to flat scars only. For deeper scars, use this concentrate until skin granulation forms over the injury, then use the Calendula Blossom Cream on top of the concentrate for at least two weeks. Then follow with the cream for the last four weeks.
