Stretch marks have a lot to do with genetics and physique. Your uterus expands when the fetus grows along the pregnancy journey.  Your abdominal circumference is getting bigger too. When the skin pulled tight, the connective tissue, like collagen and elastic fiber, will be stretched to beyond its elasticity limit. Another possible reason is the increased level of epinephrine and steroid during pregnancy may weaken the expansion ability of the connective tissue. Stretch marks are more likely to develop in multiple-pregnancy than single-pregnancy. They often develop in areas like belly, breasts, buttocks, and thighs. Often starts as reddish wavy stripes, but after pregnancy, the marks gradually fade to white or grey lines. Unfortunately, once the stretch marks has developed, there is almost no way to get rid of them.

Therefore, it is recommended to start with prevention by managing weight gain during pregnancy. Keep the weight gain within the normal range by gaining no more than 2kg per month. The total weight gain should be around 11-14kg throughout the pregnancy. At the beginning of pregnancy, you can apply the maternity moisturizer and massage gently on tights, belly, and chests twice daily, morning and night. It helps to reduce skin tension and increase the elasticity of epidermis and dermis. It also helps reduce the opportunity of stretch marks development by stretching the skin further. Besides, applying lotion and massage helps to moisturize the skin depending on the skin condition, and carry out the touch stimulation and fetal education at the same time.
