Supplement:
I think we must wear some auxiliary things. I used Vichy products before, which were especially suitable for people who lost weight, but I didn't go on a special diet at that time, so my skin didn't feel very loose, but it really felt tight.
I just found a description, you can refer to it:
At the same time, aiming at the loss of skin elasticity, Vichy also launched the Vichy body firming elastic repair milk-Lipo Stretch. Especially for the skin with repeated weight changes, the compactness and extensibility of the body skin gradually decrease, and the skin loses elasticity, so it can be used on the whole body skin. Restore skin compactness and figure curve from three aspects: skin elasticity, skin compactness and contour line. It contains innovative elastic repair essence Fylastine, which activates elastic fiber synthesis and creates firm and elastic skin. Stimulate the synthesis of collagen fibers in skin tissue and make the skin structure more compact; Rebuild skin tissue connection and reshape body curve. There is no seasonality, and it is suitable for use all year round, especially after dieting and losing weight.
