In aromatherapy it is saidthat certain essential oils can be a big help to someone with stretchmarks.  They suggest the essential oils of lavender and myrrh to treat the stretchmarks.   To make an anti stretch mark treatment oil mix three drops of frankincense and three drops of myrrh along with six drops of lavender, four drops of geranium and two fluid ounces of calendula carrier oil.  You need to apply this oil to the breasts, thighs, stomach and back side regularly.  Use it every morning and every night.  The best time to start using this oil is about the forth month of your pregnancy.   Remember when mixing essential oils it is best to keep them in a dark glass bottle.  Most of them are brown or blue and usual come with a dropper.  You can use either the brown or the blue bottles but somewhere I read that the brown bottle is better.  I believe the reason for using the dark bottles is because it blocks more of the lite from the oil.   It stays fresher in the dark bottles.   The dropper are very important when you are using essential oils.  They are the way the oil is measured.  It is important to be accurate with the measurements when using essential oils if you are looking for a particular effect.
