Is there any way to reduce future stretch marks?

Avoid weight gain: Stretch marks come from rapid weight gain, hormones, pregnancy, and are dermal tears that cause discoloration. They occur wherever you accumulate fat including upper arms, abdomen, buttocks, thighs, shoulders and back. They have loss of elastin and collagen. Stay at a normal weight, stay fit, and keep your hormones balanced by not taking steroids when you work out.
