How to prevent the appearance of stretch marks. First of all, in addition to irresistible genetic factors, like dry epidermis and excessive weight gain are important factors that lead to the appearance of stretch marks. Pregnant women can start with the following two situations: 1. Epidermal dryness: pregnant women can use emollient creams for application to keep the epidermal skin moisturized and resist epidermal tension, thus sharing the tension of the dermis. Once the stretch marks of pregnant women are formed, any products used externally will have no effect on it, so pregnant women should do a good job of comprehensive protection to prevent stretch marks before they are formed; 2, strengthen exercise and reasonable diet: prevent excessive weight growth, protect the integrity of the epidermis and resist the tension brought by the dermis. Through the above two conditions, pregnant women can effectively prevent the appearance of stretch marks.
