It is very common and completely normal to get stretch marks during a rapid growth spurt. As your body grows, the skin stretches quickly, leaving these harmless marks. While they cannot be completely erased, they naturally fade from red or purple to faint, silvery lines over time. For newer marks, prescription generic tretinoin cream (a retinoid) can help rebuild collagen and improve their appearance. Over-the-counter creams containing hyaluronic acid or centella asiatica can also support skin elasticity. Keeping the area well-moisturised is key. I highly recommend consulting a dermatologist to discuss these options safely.
