Good question. Tension across the wound is perhaps the worst thing for a healing wound. Keeping tape or a steri-strip or silicone sheeting probably help the best during the initial healing phase. Some women will use their special ointment, vitamin E, etc to improve the scar. If the ointment or cream can penetrate the skin, then it may be of some limited benefit. Keeping the tape over the incision for a month really works the best. Unfortunately, most women prefer to remove the tape for comfort. Then apply the ointments, etc.
