Generally speaking, the scar formed by this operation needs to be removed by physical means, that is, photonics and other operations. If it is flat, such as a small wound and a small scar left after healing, lavender essential oil should be used for a long time as soon as possible, and a small amount should be applied several times. Lavender essential oil was originally thought to be used to remove burn scars and promote wound healing. Therefore, when there is a wound, the earlier you use it, the better the effect will be. If the wound heals for too long, it will basically have no effect.
